vissidarte27: thanks for that. You're the (wo)man.
Couple of subjective suggestions I can make for RC: first, always read actively and focus on the big picture; don't get lost in the details-- there's a lot of information in the passage that will never come up in the questions, so there's not much point in trying to remember all the minute facts. However, you MUST know where to reference the passage should a question arise that calls for specific information; this requires you to have knowledge of the structure of the passage. It helps me to notate the purpose of each paragraph as I read, e.g., 1st is an explanation of a phenomenon, 2nd is a traditional hypothesis to explain this behavior, 3rd is presents an alternative hypothesis that shows promise but has not yet been widely accepted.
Second, you may want to notate key parts of the passage, such as examples, lists, dates of significance, analogies, viewpoints of the various parties, and changes in direction/tone, e.g., but, yet, however, nevertheless, notwithstanding, etc. Questions very often look to test your knowledge of these points.
Third, there is almost always a question about main point, and the main point can almost always be found in the last sentence of the first paragraph or somewhere in the last paragraph.
Forth, the majority of RC questions are must be true. When comparing answer choices, I find it useful not to look for the best sounding choice, but rather what must be true on the basis of the information given in the passage.
Hope that helps
EDIT: just wanted to share that in the spirit of reciprocation, even if it doesn't help in the review of incorrect answers
