Hi @Shiyi-Zhang,

(D) is incorrect because the conclusion in the question talks about cooling the atmosphere, whereas (D) talks about how the atmosphere is warmed. It also doesn't talk about reflection of what. Hope this helps.

I don't understand this explanation? The correct answer (c) also talks about warming?

Could we please get a better explanation as to why D is incorrect?

Very Hard strenghten. I was stuck between "C" and "D." Even "E" came up as a potential answer. I think I still have a great difficulty in understanding causal reasoning. I know about the ways of strenghtening a causal argument but identifying the causal assumption and understanding especially the answer choices seems particularly difficulty still. I chose D because it looked like it was eliminating a potential alternate cause to the argument. If the atmosphere derives most of its heat from the passage of light through than there is not something else in snow or ice that could potentially offset their cooling effect on the atmosphere. Please help me out with the question. Really hard and I need a step by step breakdown of it.
