Main Point question, I agonize between B and E. B is wrong because they never said it was not the only factor? But isn't E wrong as well because the conclusion was about unlikely that a prediction will occur where as E said probably will not? Isn't E kind of too definitive?
Comments
B is incorrect because it is not the main point. 95% of the time or more, the main point can be selected directly from the passage with just a simple rephrasing (the way it's done here).
"But" is a big indicator here, and it shows that a shift is being made. The point of the argument is to discredit the prediction made by those who say global warming will cause more frequent storms, so the first two sentences are just putting the conclusion in context, and the last sentence is the support for the conclusion.
Hope this helps!
