Answer choice A

@shafieiava, Let's take a look at (A). The paradox we're trying to solve is why the highest mountains on earth would be where the forces of erosion are most prevalent. One would think that the erosion would make them smaller mountains. We need an answer choice that explains how these two seemingly contradictory facts can coexist. (A) says, "Patterns of extreme wind and precipitation often result from the dramatic differences in elevation commonly found in the highest mountain ranges." (A) would help resolve the paradox because it tells us that higher mountain ranges tend to result in an increase in wind and precipitation, which help to explain why these things are commonly found together. This resolves the paradox, so it's the correct answer choice. Does this answer your question? Let us know if you have any other questions!

Thanks for your explanation. In this case would you say that answer choice B actually weakens/doesn't resolve the paradox because it is saying that there is less erosion reducing vegetation. If B said there was more erosion reducing vegetation would it help solve the paradox?
