Question 1

A city's crime rate dropped after a new police chief was appointed. A resident concludes the chief caused the drop. What alternative explanation should be considered?

Accepted Answer

Crime rates naturally fluctuate due to economic and demographic factors unrelated to leadership

Answer

Post hoc reasoning mistakes temporal sequence for causation; external factors like economic changes may explain the crime rate drop independently.

Question 2

An engineer faces a design problem with no known solution. She decides to reframe it as: 'How might we achieve the same function with different materials?' This technique is called:

Accepted Answer

Problem reframing

Answer

Problem reframing involves restating the problem from a different perspective to unlock new solution pathways not visible under the original frame.

Question 3

Which action reflects the highest level of critical thinking in the problem-solving process?

Accepted Answer

Evaluating the effectiveness of a solution after implementation and revising accordingly

Answer

The highest level of critical thinking includes reflective evaluation—assessing outcomes and adjusting based on evidence rather than treating the process as complete after implementation.

Question 4

A school finds that students who eat breakfast score higher on tests. The principal concludes that providing free breakfast will raise test scores for all students. The conclusion is:

Accepted Answer

Potentially flawed because students who eat breakfast may differ in other ways that affect scores

Answer

Self-selection bias may mean breakfast-eating students differ systematically from non-eaters, making the causal inference from correlation unreliable.

Question 5

A project manager must decide under conditions of incomplete information and time pressure. The most defensible approach is to:

Accepted Answer

Make the best decision possible with available evidence while documenting assumptions

Answer

When perfect information is unavailable, making a reasoned, documented decision with stated assumptions is the responsible and practical approach.
