Explanation
A. (Correct Response) The passage specifically addresses the role of sulfates in the earth's atmosphere in the second paragraph. It explains that sulfates reflect solar energy back into space, which has implications for temperature by counteracting the heating effect of greenhouse gases.
B. The passage does not claim that airborne sulfates are the main greenhouse gases; instead, it speaks to their role in mitigating the greenhouse effect.
C. There is no mention of the duration of solar energy cycles in the passage.
D. The passage does not provide predictions about the effects of global warming on glacial ice.
E. While the passage does mention sulfates from "natural sources such as volcanoes" and "technological sources," it does not provide a specific example of a technological source.
The specific reference to the effect of sulfates on temperatures can be found in the second paragraph of the passage, where it is discussed how sulfates from both natural and technological sources can reflect solar energy back into space, affecting global temperatures.
