Concept:Critical thinking involves analyzing, evaluating, and applying reasoning to form judgments, not just describing or recalling facts.
Explanation:Option A asks only to describe processes. Option C asks only to describe roles. Both require simple recall, not critical thinking.
Option B asks "Why is it important?" This forces students to analyze the purpose and evaluate the significance of question hour. It demands reasoning and justification.
Option D asks students to imagine being an MLA and create their own questions. This requires applying knowledge to a new situation and thinking creatively.
Thus, only options B and D provide greater scope for developing critical thinking skills.
Answer:Option C (Only B and D)
