1. Coding Guide: Elm St 1–100 → A; Elm St 101–200 → B; Pine Rd 1–50 → C; all other addresses → D. Which code applies to 75 Elm St?
- A.A✓ Answer
- B.B
- C.C
- D.D
The number 75 falls within the 1–100 range listed for Elm St, which the guide assigns to Route A. Each address is matched to the single range that contains both its street name and its number.

2. Coding Guide: Elm St 1–100 → A; Elm St 101–200 → B; Pine Rd 1–50 → C; all other addresses → D. Which code applies to 150 Elm St?
- A.A
- B.B✓ Answer
- C.C
- D.D
The number 150 lies between 101 and 200 on Elm St, the range the guide maps to Route B. It falls above the 1–100 (A) band but within the 101–200 (B) band, so B is the only correct code.

3. Coding Guide: Elm St 1–100 → A; Elm St 101–200 → B; Pine Rd 1–50 → C; all other addresses → D. Which code applies to 25 Pine Rd?
- A.A
- B.B
- C.C✓ Answer
- D.D
The street name must match before the number: 25 is on Pine Rd, whose 1–50 range is assigned to Route C. The Elm St ranges do not apply because the street name differs.

4. Coding Guide: Elm St 1–100 → A; Elm St 101–200 → B; Pine Rd 1–50 → C; all other addresses → D. Which code applies to 320 Elm St?
- A.A
- B.B
- C.C
- D.D✓ Answer
The highest Elm St range in the guide ends at 200, so 320 is not contained in any listed range. Any address that falls outside every listed range defaults to Route D.

5. Coding Guide: Elm St 1–100 → A; Elm St 101–200 → B; Pine Rd 1–50 → C; all other addresses → D. Which code applies to 60 Pine Rd?
- A.A
- B.B
- C.C
- D.D✓ Answer
Pine Rd is listed only for 1–50, and 60 is above that range, so no listed range contains it. A number outside the listed range for its own street still defaults to Route D.

6. Coding Guide: Sunset Blvd 5000–5999 → A; Sunset Blvd 6000–6999 → B; Grand Ave 1–999 → C; all other addresses → D. Which code applies to 5400 Sunset Blvd?
- A.A✓ Answer
- B.B
- C.C
- D.D
The number 5400 sits inside the 5000–5999 band for Sunset Blvd, which the guide codes as Route A. It is below the 6000 start of the B band, so A is correct.

7. Coding Guide: Sunset Blvd 5000–5999 → A; Sunset Blvd 6000–6999 → B; Grand Ave 1–999 → C; all other addresses → D. Which code applies to 6500 Sunset Blvd?
- A.A
- B.B✓ Answer
- C.C
- D.D
The number 6500 is within the 6000–6999 Sunset Blvd band assigned to Route B. It is above the 5999 ceiling of the A band, so it moves to the next-higher range, B.

8. Coding Guide: Sunset Blvd 5000–5999 → A; Sunset Blvd 6000–6999 → B; Grand Ave 1–999 → C; all other addresses → D. Which code applies to 500 Grand Ave?
- A.A
- B.B
- C.C✓ Answer
- D.D
The number 500 falls in the 1–999 range for Grand Ave, coded as Route C. The Sunset Blvd bands are irrelevant because the street name is different.

9. Coding Guide: Sunset Blvd 5000–5999 → A; Sunset Blvd 6000–6999 → B; Grand Ave 1–999 → C; all other addresses → D. Which code applies to 7200 Sunset Blvd?
- A.A
- B.B
- C.C
- D.D✓ Answer
The highest Sunset Blvd range ends at 6999, so 7200 exceeds every listed range for that street. Addresses above all listed ranges default to Route D.

10. Coding Guide: King St 10–40 → A; King St 41–80 → B; Queen St 100–150 → C; all other addresses → D. Which code applies to 40 King St?
- A.A✓ Answer
- B.B
- C.C
- D.D
Range endpoints are inclusive, so 40 is the last number in the 10–40 band and belongs to Route A. It has not yet reached 41, the start of the B band.

11. Coding Guide: King St 10–40 → A; King St 41–80 → B; Queen St 100–150 → C; all other addresses → D. Which code applies to 41 King St?
- A.A
- B.B✓ Answer
- C.C
- D.D
41 is the inclusive lower endpoint of the 41–80 band, so it belongs to Route B, not to the 10–40 (A) band that ends at 40. Adjacent ranges never overlap, so the boundary number goes to exactly one route.

12. Coding Guide: King St 10–40 → A; King St 41–80 → B; Queen St 100–150 → C; all other addresses → D. Which code applies to 120 Queen St?
- A.A
- B.B
- C.C✓ Answer
- D.D
120 is on Queen St and falls inside its 100–150 range, which the guide codes as Route C. The King St bands do not apply because the street name is different.

13. Coding Guide: King St 10–40 → A; King St 41–80 → B; Queen St 100–150 → C; all other addresses → D. Which code applies to 90 Queen St?
- A.A
- B.B
- C.C
- D.D✓ Answer
Queen St is listed only for 100–150, and 90 is below that range, so no listed range contains it. A number below its street's listed range still defaults to Route D.

14. Memory section — memorize this guide: Route A = Baker St 200–400; Route B = Baker St 401–600; Route C = Cedar Ln 1–75; Route D = all mail not covered above. From memory, which route handles 350 Baker St?
- A.A✓ Answer
- B.B
- C.C
- D.D
350 lies inside the Baker St 200–400 range, which is memorized as Route A. In the memory section you must recall the mapping without the guide in view, but the matching rule is identical to the coding section.

15. Memory section — memorize this guide: Route A = Baker St 200–400; Route B = Baker St 401–600; Route C = Cedar Ln 1–75; Route D = all mail not covered above. From memory, which route handles 500 Baker St?
- A.A
- B.B✓ Answer
- C.C
- D.D
500 falls in the Baker St 401–600 range, memorized as Route B. It is above the 400 ceiling of Route A, so it belongs to the next Baker St band, B.

16. Memory section — memorize this guide: Route A = Baker St 200–400; Route B = Baker St 401–600; Route C = Cedar Ln 1–75; Route D = all mail not covered above. From memory, which route handles 50 Cedar Ln?
- A.A
- B.B
- C.C✓ Answer
- D.D
50 is on Cedar Ln and sits within its 1–75 range, memorized as Route C. The street name must be recalled first, which rules out the Baker St routes.

17. Memory section — memorize this guide: Route A = Baker St 200–400; Route B = Baker St 401–600; Route C = Cedar Ln 1–75; Route D = all mail not covered above. From memory, which route handles 90 Cedar Ln?
- A.A
- B.B
- C.C
- D.D✓ Answer
Cedar Ln is covered only through 75, so 90 exceeds its range and matches no memorized band. Route D is the catch-all for any address not covered by A, B, or C.

18. Memory section — memorize this guide: Route A = Baker St 200–400; Route B = Baker St 401–600; Route C = Cedar Ln 1–75; Route D = all mail not covered above. Which address range is assigned to Route B?
- A.Baker St 200–400
- B.Baker St 401–600✓ Answer
- C.Cedar Ln 1–75
- D.Cedar Ln 76–150
The guide defines Route B as Baker St 401–600. This reverse-recall question tests remembering the range for a given route, the core skill of the memory section. Baker St 200–400 is Route A and Cedar Ln 76–150 appears nowhere in the guide.

19. Memory section — memorize this guide: Route A = Baker St 200–400; Route B = Baker St 401–600; Route C = Cedar Ln 1–75; Route D = all mail not covered above. Which address range is assigned to Route A?
- A.Cedar Ln 1–75
- B.Baker St 200–400✓ Answer
- C.Baker St 401–600
- D.all uncovered mail
The guide assigns Route A to Baker St 200–400. Cedar Ln 1–75 is Route C, Baker St 401–600 is Route B, and 'all uncovered mail' describes Route D — so only Baker St 200–400 matches Route A.

20. Memory section — memorize this guide: Route A = Baker St 200–400; Route B = Baker St 401–600; Route C = Cedar Ln 1–75; Route D = all mail not covered above. From memory, which route handles 700 Baker St?
- A.A
- B.B
- C.C
- D.D✓ Answer
Baker St is memorized only through 600 (Routes A and B combined), so 700 falls above every Baker St band and matches no listed range. It therefore routes to the catch-all, Route D.
