NYC Logical and Deductive Reasoning 3

Question 1

Statements: 'All evidence must be logged. Some logged items are photographs.' Which conclusion is definitely true?

Accepted Answer

All logged items are evidence

Answer

All evidence must be logged, so every piece of evidence is among the logged items.

Question 2

A sergeant assigns tasks so that: if Task A is assigned, Task B must also be assigned; if Task B is assigned, Task C must be assigned. Task C was NOT assigned. What can be concluded?

Accepted Answer

Neither Task A nor Task B was assigned

Answer

By contrapositive: no C means no B, and no B means no A — so neither A nor B was assigned.

Question 3

Officers are assigned to precincts based on seniority: the most senior officer gets first choice. If Officer Kim has more seniority than Officer Lee, and Officer Lee has more seniority than Officer Park, who picks their precinct last among the three?

Accepted Answer

Park

Answer

Park has the least seniority among the three and therefore picks last.

Question 4

A dispatcher notes: 'Units are only dispatched to a scene if there is a confirmed incident.' Unit 7 was dispatched. What must be true?

Dispatch only occurs with a confirmed incident; since Unit 7 was dispatched, an incident was confirmed.
