Correct answer: Option D — 72 minutes fast. Total gain = rate × elapsed time = 6 × 12 = 72 minutes. Because the clock gains time, it is 72 minutes fast, not slow. Option A (72 minutes slow) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option B (66 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (78 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Correct answer: Option C — 45 minutes fast. Total gain = rate × elapsed time = 5 × 9 = 45 minutes. Because the clock gains time, it is 45 minutes fast, not slow. Option A (45 minutes slow) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option B (40 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (50 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Correct answer: Option B — 24 minutes fast. Total gain = rate × elapsed time = 4 × 6 = 24 minutes. Because the clock gains time, it is 24 minutes fast, not slow. Option A (24 minutes slow) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (20 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (28 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Correct answer: Option A — 45 minutes fast. Total gain = rate × elapsed time = 3 × 15 = 45 minutes. Because the clock gains time, it is 45 minutes fast, not slow. Option B (45 minutes slow) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (42 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (48 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Correct answer: Option D — 24 minutes fast. Total gain = rate × elapsed time = 2 × 12 = 24 minutes. Because the clock gains time, it is 24 minutes fast, not slow. Option A (24 minutes slow) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option B (22 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (26 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Correct answer: Option C — 54 minutes fast. Total gain = rate × elapsed time = 6 × 9 = 54 minutes. Because the clock gains time, it is 54 minutes fast, not slow. Option A (54 minutes slow) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option B (48 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (60 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Correct answer: Option B — 30 minutes fast. Total gain = rate × elapsed time = 5 × 6 = 30 minutes. Because the clock gains time, it is 30 minutes fast, not slow. Option A (30 minutes slow) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (25 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (35 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Correct answer: Option A — 40 seconds. 6 strikes contain 5 intervals, so one interval lasts 25/(5) = 5 seconds. 9 strikes contain 8 intervals, taking 40 seconds. Option B (41 seconds) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (39 seconds) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (42 seconds) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Correct answer: Option D — 24 seconds. 5 strikes contain 4 intervals, so one interval lasts 16/(4) = 4 seconds. 7 strikes contain 6 intervals, taking 24 seconds. Option A (25 seconds) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option B (23 seconds) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (26 seconds) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.

Correct answer: Option C — 12 seconds. 10 strikes contain 9 intervals, so one interval lasts 27/(9) = 3 seconds. 5 strikes contain 4 intervals, taking 12 seconds. Option A (13 seconds) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option B (11 seconds) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (14 seconds) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.
