LEAB Deductive & Inductive Reasoning 2 — Questions and Answers
Question 1: All armed robbery suspects must be photographed and fingerprinted. Marcus is a suspect in an armed robbery. Which conclusion is definitely true?
- Marcus will be released after questioning
- Marcus must be photographed and fingerprinted (Correct answer)
- Marcus will be charged with a felony
- Marcus will be placed in a lineup
Correct answer: Marcus must be photographed and fingerprinted
The rule applies universally to all armed robbery suspects, so it must apply to Marcus.
Question 2: Officer Reyes notices that the last four burglaries in the district all occurred between 2 AM and 4 AM on weekdays. What is the most reasonable inductive conclusion?
- All future burglaries will happen on weekdays
- The burglar works a day job and strikes at night on workdays (Correct answer)
- Weekend patrols should be increased immediately
- The burglaries are unrelated to each other
Correct answer: The burglar works a day job and strikes at night on workdays
The consistent pattern of weekday late-night timing inductively suggests the offender has daytime obligations.
Question 3: If a vehicle is reported stolen AND the driver cannot produce a valid license, the officer must detain the driver. A driver produces a valid license but the car is reported stolen. What must the officer do?
- Release the driver immediately
- Detain the driver because both conditions are met
- Detain the driver because the stolen vehicle condition is still met with both together (Correct answer)
- Issue a citation only
Correct answer: Detain the driver because the stolen vehicle condition is still met with both together
Both conditions (stolen vehicle AND no valid license) must be present to trigger mandatory detention; here only one is met so the rule does not automatically apply — but the officer must still investigate the stolen vehicle.
Question 4: Investigators find that three separate witnesses described the getaway car as dark-colored, four-door, and American-made. A detective spots a dark-colored, four-door Ford. What is the strongest inductive inference?
- The Ford is definitely the getaway car
- The Ford matches witness descriptions and warrants closer investigation (Correct answer)
- Witnesses are unreliable so the Ford should be ignored
- Only American-made cars commit crimes in this area
Correct answer: The Ford matches witness descriptions and warrants closer investigation
Matching multiple independent witness details raises the car's investigative priority but does not confirm guilt.
Question 5: Policy: Officers must complete a use-of-force report within 24 hours of any incident involving force. Officer Chen used force during an arrest on Monday at 11 PM. By when must the report be submitted?
- Tuesday at 11 AM
- Tuesday at 11 PM (Correct answer)
- Wednesday at 8 AM (start of next shift)
- Wednesday at 11 PM
Correct answer: Tuesday at 11 PM
24 hours after Monday at 11 PM is Tuesday at 11 PM, regardless of shift schedules.
Question 6: Every time Officer Park has responded to calls at a particular apartment complex, she has found at least one person without proper identification. She responds there again. What is the most reasonable inductive prediction?
- She will definitely find someone without ID
- She will likely encounter someone without ID based on the established pattern (Correct answer)
- The pattern is meaningless because every call is unique
- She should not respond to calls at that location
Correct answer: She will likely encounter someone without ID based on the established pattern
Past consistent outcomes support a probable — not certain — expectation of a similar outcome.
Question 7: No juvenile suspect may be held in the same cell as an adult suspect. Offender A is 17 years old. Offender B is 19 years old. Which statement is definitely true?
- Both must be released within 24 hours
- Offender A and Offender B cannot share a cell (Correct answer)
- Offender B must be held in a juvenile facility
- Offender A is exempt from all adult processing rules
Correct answer: Offender A and Offender B cannot share a cell
Offender A is a juvenile (under 18) and Offender B is an adult, so the rule prohibits them from sharing a cell.
