SEHS Critical Thinking and Problem Solving 3

Question 1

Which cognitive skill involves evaluating the credibility and logic of an argument rather than simply accepting it at face value?

Accepted Answer

Critical analysis

Answer

Critical analysis involves questioning assumptions, evaluating evidence, and assessing the strength of reasoning.

Question 2

A clock shows 3:45. What is the angle between the hour hand and the minute hand?

Accepted Answer

157.5°

Answer

At 3:45, the minute hand is at 270° and the hour hand is at 3×30 + 45×0.5 = 112.5°, giving a difference of 270 − 112.5 = 157.5°.

Question 3

Accepted Answer

5

Answer

Using inclusion-exclusion: 18 + 12 − 5 = 25 do at least one activity; 30 − 25 = 5 do neither.
