The following text discusses the coffee industry.
Coffee cultivation supports millions of farmers worldwide, primarily in tropical regions. However, climate change threatens coffee-growing areas with rising temperatures and unpredictable rainfall. Scientists are developing heat-resistant coffee varieties to address these challenges. Meanwhile, some farmers are relocating their operations to higher, cooler elevations.
Which choice best describes the function of the third sentence?
It questions whether climate change actually affects coffee.
It describes how scientists are responding to the problem.
It explains the history of coffee cultivation.
It compares different coffee varieties.
Correct Answer: B
Choice B is the best answer. The third sentence describes scientists developing heat-resistant varieties—a direct response to the climate change problem mentioned in sentence two.
- Evidence: Sentence 2 mentions the problem: "climate change threatens." Sentence 3 states: "Scientists are developing heat-resistant varieties to address these challenges."
- Reasoning: Developing a new variety is a scientific response to the stated threat.
- Conclusion: The function is to describe this response.
đź’ˇ Strategy: Connect the problem (climate change) to the action taken (developing varieties).
Choice A is incorrect because climate effects are accepted, not questioned. Choice C is incorrect because cultivation history isn't discussed. Choice D is incorrect because varieties aren't compared for taste/quality.
