Still quite confused

I can see how your explanation makes sense, but I still don't fully understand why B is a better choice. I thought that the comparison within the "Rocky Mountain" was more important than comparison drawn from other mountainous regions, because we have no specific information on the other mountainous regions as to where its located and the general conditions.

Hi @kenken,

Thanks for the question! I assume that the two answers you’re comparing are (B) and (C), but let me know if I’m mistaken. The issue with (C) is that it only offers a correlation between the areas of the Rocky Mountains in which winters are relatively mild and having less storable water, as we can see in the wording “…there is less.” But in (B), we’re given a causal link between the other mountainous regions and less storable water, as seen by the wording “…the melting of snowpacks has led to greater spring flooding and less storable water.” Since there’s no reason to assume that the Rocky Mountains would be different from other mountainous regions, and the link here is causal rather than correlative, (B) is a better answer choice than (C). Where exactly the other mountainous regions are or their general conditions outside of the information the passage has given us is irrelevant.

Hope this helps! Feel free to ask any other questions that you might have.
