40 Paragraph Comprehension (PC) Practice Questions & Answers

1. 1. Passage: A lighthouse keeper's most tedious duty was not tending the lamp but cleaning it. Soot from the burning oil settled on the glass lenses every night, and a film too thin to notice from inside could shorten the beam's reach by miles. Keepers therefore polished the lenses each morning, in any weather, before allowing themselves to sleep. According to the passage, why did keepers polish the lenses every morning?

   • A.Cleaning the lamp was the most tedious of all the duties a lighthouse keeper had to perform.
   • B.Keepers were not permitted to sleep until after sunrise.
   • C.Even a layer of soot too thin to notice could cut how far the light reached.✓ Answer
   • D.Oil lamps stopped burning unless their glass was kept clean.

   Detail (stated and reworded fact). The passage supplies the reason outright: a film 'too thin to notice' could 'shorten the beam's reach by miles,' which the choice saying even an unnoticeable layer of soot could cut how far the light reached restates in different words. On ASVAB PC detail items the key is normally a paraphrase, not a verbatim copy. The choice saying cleaning the lamp was the most tedious duty is genuinely stated in the passage but answers a different question (what was most tedious) — the single most common miss on this test. The choices claiming keepers could not sleep until after sunrise and that oil lamps went out unless the glass was clean introduce facts the passage never gives.

2. 2. Passage: Cast iron cookware is prized less for how quickly it heats than for how steadily it holds heat once hot. The metal is thick and dense, so it warms slowly and unevenly over a burner; but after several minutes it stores enough energy to keep its temperature nearly constant when cold food is dropped into it. Cooks who sear meat depend on that steadiness. The passage states that cooks who sear meat rely on cast iron because it:

   • A.spreads heat unevenly across the burner
   • B.is thicker and denser than other cookware
   • C.heats faster than thinner pans do
   • D.barely loses temperature when cold food is added✓ Answer

   Detail (reworded fact). The last two sentences link 'keep its temperature nearly constant when cold food is dropped into it' to what searing cooks depend on, and the choice saying it barely loses temperature when cold food is added is that idea in other words. The claim that it heats faster than thinner pans is contradicted (the passage says it warms slowly). The choices about spreading heat unevenly and being thicker and denser are both true statements from the passage, but they are causes or drawbacks, not the benefit the question asks about — partially-true, true-but-irrelevant options are planted deliberately.

3. 3. Passage: The apprentice was told to arrive at the workshop at six, though the master rarely appeared before nine. In those three hours the apprentice swept the floor, sharpened every chisel, and laid out the day's timber. When the master did arrive, he began cutting at once and did not stop to hunt for a tool all morning. It can be inferred from the passage that:

   • A.the apprentice hoped that by arriving early he would one day become a master himself
   • B.the workshop's main product was furniture built from the timber laid out each day
   • C.the apprentice's early hours existed so that the master's own work would not be interrupted✓ Answer
   • D.the master was lazy and left the genuinely hard work of the shop to the apprentice

   Inference. A valid ASVAB inference is a small, necessary step from the text: the apprentice's three tasks (sweeping, sharpening, laying out timber) are exactly what lets the master cut 'at once' without hunting for a tool, so the early start serves the master's uninterrupted work. A over-infers a judgment the passage never licenses; B and C import information that simply is not there. Under-inferring (rejecting D because it is not stated word for word) is the other common error.

4. 4. Passage: Visitors who expect the marsh to be silent are corrected within a minute of stepping onto the boardwalk. Frogs start up in ragged waves, insects hum at a pitch that seems to come from every direction at once, and unseen birds rattle the reeds. Only in the coldest weeks of the year does the place approach the stillness people imagine. The passage indicates that the marsh is NOT:

   • A.home to frogs
   • B.quiet during most of the year✓ Answer
   • C.reachable on foot
   • D.colder at some times of year than at others

   Inference with a negative stem. NOT/EXCEPT/LEAST stems invert the task: three options are supported and you pick the odd one out. Frogs are named, a boardwalk means foot access, and 'the coldest weeks of the year' implies seasonal variation — so B, C and D are all supported. Only A is denied: the marsh approaches stillness solely in the coldest weeks, so it is noisy most of the year. Missing the word NOT is one of the most common ways strong readers lose points.

5. 5. Passage: The inspector called the crack in the beam 'superficial,' and the crew relaxed. It ran along the painted face only, stopping well short of the timber's core, and a coat of filler would hide it. Had the split reached deeper, the whole span would have had to come down. As used in the passage, the word 'superficial' most nearly means:

   • A.certain to spread over time
   • B.careless or shallow in thinking
   • C.affecting only the outer layer✓ Answer
   • D.too small to be seen at all

   Word-in-context. PC vocabulary items are decided by the surrounding sentences, not by a word's most familiar dictionary sense. Here the next sentence defines it: the crack 'ran along the painted face only, stopping well short of the timber's core' — that is D. A is the common figurative sense applied to people and is the planted trap; B is contradicted by the crew's relief; C is refuted because the inspector saw the crack.

6. 6. Passage: Early clocks were set by the sun, so noon in one town differed from noon in the next. Stagecoaches could tolerate the difference; trains could not. The railways forced the adoption of a single shared time, because a timetable means nothing if every station keeps its own hour. Stations that resisted hung two sets of hands on one dial, local and railway, before abandoning local time altogether. The main idea of this passage is that:

   • A.railway timetables made a single shared standard of time necessary✓ Answer
   • B.early clocks were inaccurate because they depended on the sun
   • C.some clock faces once carried two sets of hands
   • D.coach travel was slower and less demanding than rail travel

   Main idea. The correct choice must cover the whole paragraph, and here the topic sentence is buried in the middle ('The railways forced the adoption of a single shared time'); every other sentence sets it up or illustrates it. A is a background detail and misstates it (sun time was not inaccurate, just local). B is a passing contrast. D is a single illustration — too narrow, the classic wrong main-idea answer.

7. 7. Passage: A sourdough starter is nothing but flour, water, and patience. Left in a warm place, the mixture attracts wild yeasts and bacteria from the air and from the grain itself; fed daily, the colony grows strong enough to raise a loaf. Neglected, it sours past use. The baker does not so much create the leavening as keep a household of living organisms fed. The best title for this passage would be:

   • A.Wild Yeasts in the Air
   • B.Why Bread Goes Stale
   • C.Feeding a Living Starter✓ Answer
   • D.The Chemistry of Wheat Flour

   Main idea stated as a best title. A title must fit the whole passage and nothing beyond it. Every sentence here is about tending the starter — feed it and it thrives, neglect it and it dies — which is C, and the last sentence states it outright. A is too broad and off-topic; B is never discussed; D names one supporting detail only, making it too narrow.

8. 8. Passage: Before lifting a load, set your feet shoulder-width apart and square to the object. Bend at the knees, not the waist, and keep the load close to your body as you rise. If the object shifts or your grip slips, lower it rather than trying to correct midway. A load dropped from waist height damages far less than a back strained at full extension. The author's main purpose in this passage is to:

   • A.persuade employers to ban manual lifting
   • B.trace the history of workplace safety rules
   • C.entertain the reader with a story about an injury
   • D.instruct the reader in a safe procedure✓ Answer

   Author's purpose. Purpose answers turn on the verb, and the text is written in the imperative ('set your feet,' 'bend at the knees,' 'lower it') with each step justified — that is instruction, A. B misreads the final sentence: it explains why to drop a load, not an argument for banning lifting. C and D describe writing types (historical, narrative) that never appear here.

9. 9. Passage: The new filing system arrived with some fanfare. Staff were assured it would save each of them an hour a week; the training alone consumed three. Documents that once sat in a drawer now sit in a drawer and in two databases, and the office keeps a paper index of where the digital copies live. The author's attitude toward the new filing system is best described as:

   • A.dryly skeptical✓ Answer
   • B.sorrowful and nostalgic
   • C.enthusiastic and admiring
   • D.openly outraged

   Tone. Tone is carried by word choice and by contrast: 'some fanfare' hedges the launch, the promised one hour is set against three hours of training, and the paper index of digital files is quiet irony. That is understated skepticism, D. A reverses the tone. B and C are extreme or emotional labels; on the ASVAB, strong tone words are almost always wrong unless the passage is openly emotional, and nothing here is angry or mournful.

10. 10. Passage: Maple syrup begins as sap collected in late winter, when nights freeze and days thaw. The sap is strained to remove bark and insects, then boiled for hours until most of its water has evaporated. Only after boiling is the syrup graded by color and sealed in containers. Tapping the trees, of course, must come before any of this. According to the passage, which step happens LAST?

    • A.The sap is boiled.
    • B.The trees are tapped for their sap.
    • C.The syrup is graded by color.✓ Answer
    • D.The sap is strained.

    Sequence of events. Order words fix the chain: strained, 'then' boiled, and 'only after boiling' is it graded and sealed — so grading is last, D. The trap is that tapping is mentioned last in the paragraph but the passage explicitly places it 'before any of this'; on ASVAB sequence items the order of mention often differs from the order of occurrence, so read the time words rather than the line order.

11. 11. Passage: Rust and rot look like different problems, but both are slow fires. A rusting hinge and a decaying log are each combining with oxygen and giving off heat, only so gradually that no flame appears. Burning is simply the same reaction hurried along until the heat becomes visible. The author develops this point mainly by:

    • A.quoting the published opinions of recognized authorities on the subject
    • B.comparing familiar processes to show they share one reaction✓ Answer
    • C.presenting numerical measurements as evidence
    • D.arranging the events described in chronological order

    Style and technique (passage organization). The paragraph names three familiar things — rust, rot, fire — and argues they are one reaction at different speeds; that structure is comparison by analogy, C. No dates or sequence appear (A), no source is quoted (B), and no figures are given (D). Style/technique is an officially listed PC concept and asks how the writing is built, not what it says.

12. 12. Passage: A carpenter's hand plane cuts by holding a blade at a fixed angle just beneath a flat sole. The sole is what makes the tool useful: it rides on the high points of a board and stops the blade from dropping into the hollows. A blade held in the hand alone would follow every dip in the surface it was meant to remove. According to the passage, the sole of the plane:

    • A.keeps the blade from dropping into hollows in the board✓ Answer
    • B.sharpens the blade as the tool moves
    • C.is the part of the tool that holds the blade at its fixed angle
    • D.adds weight so the blade cuts more deeply

    Detail (reworded fact). Sentence 2 assigns the sole exactly one job — riding the high points so the blade cannot drop into hollows — which is B. C is the seductive half-truth: the passage says the plane holds the blade at a fixed angle 'just beneath a flat sole,' not that the sole does the holding. A and D add mechanisms the text never mentions, the outside-knowledge trap.

13. 13. Passage: Desert shrubs are often spaced with a regularity that looks planted. Each stands well apart from its neighbors, with bare ground between. Where rain is scarce, a shrub's roots reach far wider than its canopy, and any seedling that sprouts inside that circle finds the water already spoken for. It can be inferred from the passage that:

    • A.the shrubs were deliberately planted in evenly spaced rows
    • B.the bare ground between shrubs results from competition for water✓ Answer
    • C.a shrub's canopy spreads wider than its root system does
    • D.desert soil is simply too poor in nutrients ever to support a new seedling

    Inference. The passage supplies the mechanism without naming the conclusion: roots reach beyond the canopy and take the water, so seedlings inside that radius fail — which is exactly why the ground between shrubs stays bare, C. A is contradicted by 'looks planted.' B reverses the stated relationship. D uses the absolute 'never'; the passage limits the effect to seedlings inside the root circle, and absolute qualifiers are usually planted wrong answers.

14. 14. Passage: The ledger's entries were fair in both senses. The clerk's hand was even and unhurried, each column aligned, so that a stranger could read the page at a glance; and the sums themselves favored no one, the shopkeeper's own debts recorded as plainly as his customers'. As used in the passage, 'fair in both senses' means the entries were:

    • A.beautiful and profitable
    • B.pale in color and pleasant to look at
    • C.easy to read and impartial✓ Answer
    • D.ordinary and merely acceptable

    Word-in-context. The passage defines both senses in order: the handwriting is even and legible ('a stranger could read the page at a glance') and the accounting favors no one — that is B. A and C are real dictionary senses of 'fair' (light-colored; merely adequate) that the context rules out, and choosing a familiar-but-wrong sense is the standard error here. D adds profit, which the passage never mentions.

15. 15. Passage: Sand dunes move. Wind rolls grains up the gentle windward slope and drops them over the crest, where they slide down the steep far face. No single grain travels far, but the dune as a whole creeps downwind, sometimes burying fences and roads. What looks like a fixed hill is really a slow river of sand. This passage is primarily about:

    • A.the damage moving dunes do when they bury fences and roads in their path
    • B.the fact that a dune is a slowly moving accumulation rather than a fixed hill✓ Answer
    • C.how much harder the wind blows on a dune's windward slope than on its sheltered face
    • D.the idea that wind is responsible for every desert landform

    Main idea. The first and last sentences frame the whole paragraph — 'Sand dunes move' and 'a slow river of sand' — and the middle explains the mechanism; C captures that. A is not even stated (the passage contrasts slope shapes, not wind strength). B is one consequence, too narrow. D reaches past the passage to a claim about all desert landforms, the too-broad trap.

16. 16. Passage: A good workplace checklist is short, ordered, and read aloud. Short, because a list longer than a page is skipped under pressure. Ordered, because steps that depend on one another must be confirmed in sequence. Read aloud, because a silent check is easily imagined rather than performed. Nothing on a checklist should be a task the reader has never done. The passage names all of the following as features of a good checklist EXCEPT:

    • A.It is read aloud rather than checked silently.
    • B.It is brief enough to fit on a single page.
    • C.It includes tasks the reader has never performed.✓ Answer
    • D.Its steps are confirmed in a fixed order.

    Detail with an EXCEPT stem. The first sentence lists three features — short, ordered, read aloud — so A, B and C are all supported and cannot be the answer. The final sentence says the opposite of D: nothing on the list should be a task the reader has never done. With EXCEPT/NOT stems, verify each option against the text and pick the one the passage contradicts or omits.

17. 17. Passage: The museum keeps its oldest manuscripts in a room without windows, lit only when a visitor enters and never above a certain dimness. Guides answer the same complaint every day: yes, the room is too dark to read comfortably, and no, the lights will not be turned up. The reader can conclude from the passage that:

    • A.exposure to light damages the manuscripts✓ Answer
    • B.the manuscripts are written in a language few visitors can read
    • C.the museum cannot afford better lighting
    • D.visitors are not allowed into the room

    Inference. Three deliberate measures — no windows, light only when someone is present, and a hard ceiling on brightness — are all restrictions on light, and the museum keeps them even though visitors object. The only conclusion that explains all three is that light harms the manuscripts, B. C invents a financial motive the passage never raises; A is unrelated; D is contradicted, since visitors enter and complain.

18. 18. Passage: Readers are often told that a spider's web is a trap, as if the spider had only to wait. In truth the web is rebuilt constantly, sometimes nightly, at real cost in silk and energy. Considering the labor involved, the web is less a trap than a tool the spider must maintain, and calling it anything else hides how much work goes into it. The author's chief purpose in this passage is to:

    • A.compare several species of spider
    • B.correct a common misunderstanding✓ Answer
    • C.warn readers about the danger of spiders
    • D.explain the chemistry of silk production

    Author's purpose. The structure gives it away: a widely held belief is stated ('Readers are often told...'), then reversed ('In truth...'), then replaced with a better description. That is correction, A. B misjudges the tone — nothing here is cautionary about danger. C and D name topics the passage never takes up; picking them means importing what a spider passage 'usually' contains instead of reading this one.

19. 19. Passage: The captain ordered the crew to secure the deck. Loose crates were lashed to the rail, hatches were dogged shut, and anything that could roll was carried below. Within twenty minutes nothing on deck could shift, whatever the sea did. As used in the passage, 'secure' most nearly means:

    • A.fasten things firmly in place✓ Answer
    • B.obtain or acquire something needed
    • C.clear of all people
    • D.guard against theft

    Word-in-context. The sentences after the order define it by example — lashing, dogging shut, carrying below, until 'nothing on deck could shift' — so the sense is fastening things down, B. A and C are ordinary dictionary meanings of 'secure' that the context rules out, and C in particular is the sense most readers reach for first. D describes clearing the deck of people, which the passage never says.

20. 20. Passage: Concrete does not dry; it cures. The water in the mix is not merely evaporating but reacting with cement to form crystals that lock together. That is why fresh slabs are kept damp, sometimes covered for days: a slab that loses its water too fast ends up weaker, not stronger, however hard the surface feels. According to the passage, fresh slabs are kept damp because:

    • A.the crystals form only in cold weather
    • B.covered concrete dries faster than uncovered concrete
    • C.a damp surface feels harder than a dry one
    • D.the water must react with the cement instead of escaping✓ Answer

    Detail (reworded fact) resting on a stated cause. The passage says the water reacts with cement to form interlocking crystals and that losing water too fast makes the slab weaker; A restates that causal chain. B contradicts the point of covering. C twists the last clause, which says the surface can feel hard even when the slab is weak. D adds a temperature condition the passage never mentions — the outside-knowledge trap.

21. 21. An aluminum beverage can is one of the most recycled containers in the world. Melting used cans takes about 95 percent less energy than making new aluminum from ore. Because the process is so quick, a can dropped in a recycling bin may return to a store shelf as a new can in as little as 60 days. According to the passage, how soon may a recycled can return to a store shelf?

    • A.About 60 days✓ Answer
    • B.About six months
    • C.About 6 days
    • D.About one year

    This is a stated-detail question: the final sentence says a can 'may return to a store shelf as a new can in as little as 60 days.'

22. 22. Roof vents are a simple way to keep a greenhouse healthy. Opening them on warm afternoons lowers the air temperature before plants overheat. Moving air also carries away excess humidity, which discourages mold, and the gentle motion helps seedlings grow sturdier stems. The passage mentions all of the following benefits of roof vents EXCEPT—

    • A.strengthening seedling stems
    • B.lowering the air temperature
    • C.keeping insect pests out✓ Answer
    • D.reducing excess humidity

    In a NOT/EXCEPT item you must find the one choice absent from the text: the passage names cooling, humidity removal, and sturdier stems, but never mentions insects. Pest control is true of greenhouses in real life, which is exactly the trap — an answer must be provable from the passage alone, and skipping the word EXCEPT is the most-reported cause of misses on this question type.

23. 23. You can estimate how far away a thunderstorm is without any instruments. When you see a flash of lightning, count the seconds until you hear the thunder. Sound travels about one mile every 5 seconds, so dividing your count by 5 gives the storm's distance in miles. According to the passage, to find the storm's distance in miles you should—

    • A.divide the seconds counted by 3
    • B.divide the seconds counted by 5✓ Answer
    • C.count one mile for every second heard
    • D.multiply the seconds counted by 5

    The rule is stated word for word in the last sentence: because sound covers a mile every 5 seconds, you divide the counted seconds by 5. The distractors reverse the operation or change the divisor — the standard PC trap of keeping the topic but flipping one qualifier — so the only provable choice is the division by 5.

24. 24. The harbor ferry runs every 40 minutes on weekdays. On Saturdays and Sundays, it switches to one departure per hour. Foot passengers board first, followed by riders with bicycles, and the crossing itself takes about 15 minutes. According to the passage, how often does the ferry depart on weekends?

    • A.Once per hour✓ Answer
    • B.Every 40 minutes
    • C.Every 15 minutes
    • D.Twice per hour

    The second sentence states that on Saturdays and Sundays the ferry 'switches to one departure per hour.' The 40-minute figure is the weekday schedule and 15 minutes is the crossing time — both are details pulled from the wrong part of the passage, the most common distractor pattern in detail questions.

25. 25. A few simple habits extend the life of car tires. Check the air pressure once a month, because underinflated tires wear quickly along their edges. Rotate the tires at the mileage interval listed in the owner's manual, and inspect the tread depth regularly with an inexpensive gauge. Which of the following is NOT mentioned in the passage as a tire-care habit?

    • A.Having the wheels aligned✓ Answer
    • B.Checking the air pressure
    • C.Rotating tires on schedule
    • D.Inspecting the tread depth

    The passage lists exactly three habits — pressure checks, rotation, and tread inspection — and wheel alignment never appears. Alignment is genuine real-world tire care, which is the signature PC trap: a choice can be true in life yet wrong on the test because only what the passage itself states can be credited, especially under a NOT stem.

26. 26. Books borrowed through the library's interlibrary loan service follow special rules. Because they belong to another library, they cannot be renewed. They must also be handed to a staff member at the front desk instead of being dropped in the outdoor return slot. According to the passage, an interlibrary loan book must—

    • A.be renewed before its due date
    • B.be mailed back to its owner
    • C.be returned at the front desk✓ Answer
    • D.be dropped in the return slot

    The last sentence directly requires handing the book to a staff member at the front desk. The return slot is explicitly forbidden, renewal is explicitly impossible, and mailing is never mentioned — two distractors contradict the passage and one adds information, so only the front-desk answer can be pointed to in the text.

27. 27. City trees do far more than decorate the sidewalk. Their canopies shade pavement that would otherwise radiate heat all evening, and their roots soak up stormwater that would flood the drains. Studies even link tree-lined blocks to higher property values and calmer traffic. Which of the following best states the main idea of the passage?

    • A.Shaded pavement raises property values
    • B.Tree roots are what stop street flooding
    • C.Trees mainly make sidewalks look nicer
    • D.City trees offer many practical benefits✓ Answer

    The first sentence announces the main idea — trees do 'far more than decorate' — and every later sentence supplies one supporting benefit. Shade, flood control, and property values are each too narrow because they cover only one detail, and 'mainly decorate' contradicts the opening line; the credited main idea must cover the whole passage without exceeding it.

    • A.urge readers to take a first aid class✓ Answer
    • B.explain how chest compressions are done
    • C.compare ambulance times across counties
    • D.tell the story of a dramatic rescue

    The closing command 'sign up for one this month' reveals a persuasive purpose: the facts about bystanders and survival odds are marshaled to push the reader toward action. A passage that merely explained compressions or compared response times would lack that direct appeal, and no rescue story is told — purpose questions turn on what the text does, not what it mentions.

30. 30. An octopus at one aquarium learned to unscrew jar lids to reach the crab inside. Another slipped out of its tank at night, crossed the floor, and raided a neighboring exhibit. In the wild, some carry coconut shells to use later as portable shelters. Taken as a whole, the passage suggests that octopuses are—

    • A.stronger than most sea animals
    • B.unable to survive in captivity
    • C.clever and resourceful animals✓ Answer
    • D.dangerous to aquarium staff

    The main idea here is implied rather than stated: opening jars, planning a nighttime raid, and carrying shelters for future use are three examples that all point to intelligence and resourcefulness. Nothing in the text mentions danger to people, strength, or dying in captivity — an implied main idea must synthesize what every example shares, not import outside claims.

31. 31. Budget airlines keep fares low through a strict formula. They fly a single aircraft model to simplify training and repairs, turn planes around at the gate in under 30 minutes, and often use smaller airports that charge lower landing fees. Every saved minute and fee shows up in the ticket price. This passage is mainly about—

    • A.how budget airlines keep ticket prices low✓ Answer
    • B.how gate delays raise landing fees
    • C.why flying one plane model is safest
    • D.why smaller airports charge lower fees

    The opening sentence states the controlling idea — a formula for keeping fares low — and the three practices that follow are its supporting details. Each wrong choice inflates one supporting detail into the whole topic or distorts it (the passage links one model to simpler training, not to safety), the standard too-narrow distractor pattern on main-idea items.

32. 32. The mechanic listened to the rough idle for less than a minute, then reached for a single wrench without opening the repair manual. By closing time the engine ran smoothly again. From this passage, it is reasonable to conclude that the mechanic—

    • A.replaced the entire engine that same day
    • B.never consults manuals for any repair
    • C.had seen this problem many times before✓ Answer
    • D.guessed and simply happened to be lucky

    Diagnosing by sound in under a minute, choosing the right tool immediately, and finishing the fix all point to prior experience with this exact problem — a small inferential step the text supports. 'Never consults manuals' overreaches from one instance to an absolute, luck contradicts the quick confident diagnosis, and an engine swap is stated nowhere; on PC items the credited inference is the moderate one.

33. 33. When the river bridge closed for repairs in March, drivers between the two towns faced a 30-mile detour. A café on the far side, popular with commuters, soon cut its weekday hours. Its owner said she hoped the repair crews would finish ahead of schedule. It is reasonable to conclude that the café—

    • A.raised its prices to offset the detour
    • B.moved to the other side of the river
    • C.lost commuter business after the closure✓ Answer
    • D.shut down permanently during March

    The chain is laid out in the text: the café depended on commuters, the detour cut commuter traffic, and the café then reduced its weekday hours while its owner waited for the bridge to reopen. Losing commuter business is the one-step conclusion; permanent closure overstates 'cut its hours,' and price increases or relocation appear nowhere in the passage.

34. 34. On clear, calm nights, cold air drains downhill like water and settles in valley bottoms. Growers call these low spots frost pockets. That is why many orchards are planted partway up a hillside, above the layer where the coldest air collects. It can be inferred that fruit trees planted on a valley floor—

    • A.grow sweeter fruit than hillside trees
    • B.need no protection on calm nights
    • C.face a greater risk of frost damage✓ Answer
    • D.always die during their first winter

    If the coldest air pools on the valley floor and orchards are deliberately placed above that layer to escape frost, then trees left in the bottom must face higher frost risk — the inference follows directly from the stated mechanism. 'Always die' and 'need no protection' fail the absolute-language test, and fruit sweetness is never discussed.

35. 35. By dawn the wind had died completely. Where whitecaps had pounded the breakwater all night, the harbor was now a mirror, and the fishing crews hurried down the dock to load their boats. The statement that "the harbor was now a mirror" means that—

    • A.boats could see their reflections
    • B.the docks gleamed with new paint
    • C.the water was now smooth and calm✓ Answer
    • D.the harbor had frozen overnight

    The mirror is a figure of speech: paired with 'the wind had died completely' and contrasted with the night's whitecaps, it conveys that the water's surface became flat and still. Reading it literally — actual reflections, ice, or shine — misses that figurative language on the ASVAB is interpreted by the surrounding context, which here is entirely about wind and waves subsiding.

36. 36. Seasoned travelers rarely trust memory on the morning of a flight. They keep a printed packing list and check off each item the night before. A list costs nothing, while a forgotten passport can cost the whole trip. The author of this passage would most likely agree that—

    • A.packing lists remove every travel risk
    • B.experienced travelers never forget items
    • C.memory alone is unreliable when rushed✓ Answer
    • D.passports should always be packed first

    The author's whole argument rests on one premise: on a rushed flight morning, memory fails, which is why even seasoned travelers use written lists. That premise is the view the author must hold. The other choices all break the moderation rule — 'every,' 'always,' and 'never' claim more than the passage supports, and the packing order of the passport is never addressed.

37. 37. The planning board met for three hours without reaching agreement. Rather than force a vote, the chairwoman chose to table the rezoning proposal until traffic data could be collected. Members will take the matter up again at the spring session. As used in this passage, the word "table" most nearly means—

    • A.approve
    • B.postpone✓ Answer
    • C.display
    • D.reject

    Context decides the sense: the proposal is set aside 'until traffic data could be collected' and will be 'taken up again' in spring, so the board delayed the decision rather than deciding it. In parliamentary use, to table a motion is to postpone it; the familiar furniture sense (put on display) is the trap, and approve or reject would contradict the stated lack of agreement.

38. 38. The hikers had planned to reach the shelter before dark. When the light failed sooner than expected under the heavy clouds, they stopped, set up their tent, and waited for morning. As used in this passage, the word "failed" most nearly means—

    • A.let them down
    • B.quit working
    • C.made an error
    • D.faded away✓ Answer

    The subject of 'failed' is daylight under heavy clouds, so the word takes its dimming sense: the light gradually faded before nightfall. The most familiar meanings of fail — making an error, breaking down, disappointing someone — are the trap here, because none can describe natural light; vocabulary-in-context items reward the sense the sentence forces, not the dictionary's first entry.

39. 39. The renovation crew worried that a century of storms had weakened the old barn. After probing the beams and testing every joint, however, the engineer pronounced the frame sound and cleared the project to continue. As used in this passage, the word "sound" most nearly means—

    • A.hollow
    • B.sturdy✓ Answer
    • C.noisy
    • D.audible

    The context runs from a fear that the barn was 'weakened' to an engineer's approval after structural testing, so 'sound' must mean the opposite of weakened: solid and in good condition. The noise-related senses are the familiar-meaning trap — they cannot follow from beam testing — and 'hollow' would justify stopping the project, not clearing it.

40. 40. To patch a leaking bicycle tube, first find the hole by submerging the inflated tube and watching for bubbles. Dry and mark the spot, then roughen it with sandpaper. Spread a thin layer of glue, wait until it turns tacky, and only then press the patch firmly in place. According to the passage, what should you do immediately after spreading the glue?

    • A.Press the patch on right away
    • B.Submerge the tube to test it
    • C.Roughen the spot with sandpaper
    • D.Wait for the glue to turn tacky✓ Answer

    Sequence questions are answered by the order the passage itself gives: glue is spread, then you 'wait until it turns tacky, and only then press the patch.' Pressing immediately skips the mandated wait that the phrase 'only then' guards against, while sanding and submerging are earlier steps pulled from the wrong point in the procedure.
