  1. All detectives are officers. Some officers carry badges. Which conclusion must be true?

    Answer: Some detectives may carry badges

    Since only 'some' officers carry badges, it is possible but not certain that detectives (a subset of officers) carry badges.

  2. A suspect is seen leaving the bank at 3:00 PM. The robbery occurred between 2:45 PM and 3:15 PM. What can logically be concluded?

    Answer: The suspect was present during the possible robbery window

    3:00 PM falls within the robbery window, so the suspect was present during that period, but this alone does not prove guilt.

  3. If no patrol officers work the night shift and Officer Davis works the night shift, what must be true?

    Answer: Officer Davis is not a patrol officer

    Since no patrol officers work nights and Davis works nights, Davis cannot be a patrol officer.

  4. Crimes in District A decreased by 20% this year. What additional information would best support the claim that a new policy caused the decrease?

    Answer: Districts without the policy saw no similar decrease

    Showing that districts without the policy did not experience similar decreases strengthens the causal link to the policy.

  5. Which argument contains a flaw in reasoning? 'Officer Green always solves cases quickly. This case was solved quickly. Therefore, Officer Green solved this case.'

    Answer: It commits the fallacy of affirming the consequent

    Affirming the consequent incorrectly concludes that because the result occurred, only one specific cause must be responsible.

  6. A series follows this pattern: 2, 5, 10, 17, 26, ___. What is the next number?

    Answer: 37

    The differences are 3, 5, 7, 9, 11 — odd numbers increasing by 2 — so 26 + 11 = 37.

  7. Four witnesses give conflicting accounts. Three say the car was red; one says it was blue. Which approach best reflects sound logical reasoning?

    Answer: Accept the majority view and investigate further

    The majority account provides a working hypothesis, but further investigation (e.g., traffic cameras) should corroborate it.
