  1. Study the sequence of incident numbers: 1021, 1024, 1027, 1030, ____. What is the next number?

    Answer: 1033

    Each number increases by 3, so 1030 + 3 = 1033.

  2. All felonies require a written incident report. All written incident reports must be reviewed by a supervisor. Detective Nguyen documents a felony. Which must follow?

    Answer: Nguyen's report must be reviewed by a supervisor

    By chaining both rules: felony → written report → supervisor review, so the supervisor must review Nguyen's report.

  3. A detective reviews burglary data: January 8 cases, February 12 cases, March 16 cases, April 20 cases. If the trend continues, how many cases are expected in May?

    Answer: 24

    Cases increase by 4 each month, so May is projected at 20 + 4 = 24 cases.

  4. Officers observe that every car speeding through a school zone in the past month was traveling more than 15 mph over the limit. An inductive conclusion from this data is:

    Answer: Speeders in that zone tend to significantly exceed the limit, not marginally

    The observed data supports the specific conclusion about that zone's pattern, not a city-wide universal claim.

  5. Rule: A vehicle may only be towed if it is illegally parked AND has been there for more than 2 hours OR it is blocking a fire hydrant. A car has been illegally parked for 3 hours but is not blocking a hydrant. Can it be towed?

    Answer: Yes, because it meets the illegally parked AND over 2 hours condition

    The rule has two independent grounds for towing; the car satisfies the first (illegally parked + over 2 hours).

  6. An investigator notes that of 30 DUI arrests last quarter, 27 occurred between 10 PM and 3 AM. What is the strongest inductive inference for patrol scheduling?

    Answer: Concentrating DUI patrols during 10 PM–3 AM is likely to be most effective

    90% of DUIs occurring in that window inductively supports concentrating resources there.

  7. No officer may work more than 16 consecutive hours without mandatory rest. Officer Torres began her shift at 6 AM. It is now 10 PM. A supervisor asks her to work 2 more hours. Is this permissible?

    Answer: No, because 2 more hours would bring her to 18 consecutive hours

    6 AM to 10 PM is 16 hours; adding 2 more would reach 18, violating the 16-hour maximum.
