CJBAT Logical Reasoning Questions and Answers 3

Question 1

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

Accepted Answer

Some detectives may carry badges

Answer

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

Question 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?

Accepted Answer

The suspect was present during the possible robbery window

Answer

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

Question 3

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

Accepted Answer

Officer Davis is not a patrol officer

Answer

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

Question 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?

Accepted Answer

Districts without the policy saw no similar decrease

Answer

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

Question 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.'

Accepted Answer

It commits the fallacy of affirming the consequent

Answer

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