The LSAT/GMAT Reading Comprehension Questions fall into three main categories (and lots of sub-categories)
1. Questions about the Passage "What did the author write?" 2. Questions about the Author "Why did the author write?" 3. Questions about New Information "How would the author respond to this new data or new situation?"
When you're attempting to solve an RC question, ask yourself: "Is this a 1, 2, or 3?"
