The following text is from a media theory article.
The "attention economy" framework conceptualizes human attention as a scarce resource for which platforms compete. Success is measured in engagement metrics: time on site, scroll depth, click-through rates. Critics argue this framing commodifies consciousness and incentivizes manipulative design. More optimistic voices suggest that attention markets might be structured differently, with regulations or alternative business models promoting more enriching content.
Which choice best describes the function of the last sentence?
It provides technical definitions of engagement metrics.
It presents an alternative perspective that qualifies the criticism.
It summarizes the main argument of the entire passage.
It introduces a completely different topic about social media.
Correct Answer: B
Choice B is the best answer. The last sentence presents optimistic voices as alternatives (regulations, different models), qualifying the preceding criticism.
- Evidence: The sentence states: "More optimistic voices suggest that attention markets might be structured differently."
- Reasoning: It offers a counter-perspective to the negative view ("Critics argue") presented earlier.
- Conclusion: The function is to present an alternative/qualifying perspective.
💡 Strategy: Look for "More optimistic voices" -> Alternative view.
Choice A is incorrect because definitions appear earlier. Choice C is incorrect because it adds alternatives, not summarizes. Choice D is incorrect because it continues the attention economy topic.
