Question

BlackTom AI · Accepted Answer

Challenging the prevailing economic model is the lecture’s central aim because the speaker repeatedly critiques assumptions, highlights failures, and proposes alternative perspectives rather than merely surveying models or advocating one specific plan.

1. Relevant knowledge points and concepts
- Distinguish purposes of lectures: descriptive (discussing options), advocative (promoting one model), and critical/analytical (challenging assumptions and pointing out weaknesses).
- Recognize rhetorical signals of critique: use of counterexamples, emphasis on shortcomings, calls for rethinking, and presentation of alternatives or reforms.

2. Step‑by‑step reasoning
- Note the lecture’s tone: it emphasizes problems with the current model (e.g., inequalities, inefficiencies) rather than giving a neutral survey of many models. This indicates critique rather than discussion.
- Observe content structure: the speaker lists failures, marshals evidence against core assumptions, and offers reasons to reconsider accepted practice—typical structure when challenging a model.
- Check for promotion: the lecture does not primarily present a single solution as superior or attempt to persuade toward adoption; instead it raises doubts and explores implications, which is a hallmark of a challenge.

3. Calculations/intermediate steps
- No numerical calculations are required for identifying the lecture’s purpose. Intermediate analytical steps are the identification of rhetorical features and mapping those to typical lecture aims.

4. Why the correct answer is correct
- The lecture’s emphasis on critiquing underlying assumptions, demonstrating negative outcomes, and encouraging rethinking directly aligns with “to challenge the existing economic model.” That phrasing best matches the observed intent and content.

5. Why other options are incorrect
- (a) “to discuss a range of economic models”: incorrect because the lecture is not neutral or comprehensive; it focuses on one dominant model’s flaws rather than surveying many.
- (b) “to promote a particular economic mode[l]”: incorrect because the speaker does not primarily advocate for adoption of a specific alternative; the primary activity is critique, not promotion.

6. Conclusion
- The evidence and reasoning confirm answer c. to challenge the existing economic model.
