Many RC question ask for the same type of answers: (1) what was the main idea (2) What is the relationship between the evidence and conclusion in each paragraph (3) identify a claim of certainty.

Just be aware that in RC aware that the incorrect answers usually deal with the following:

-extreme statements not supported by evidence (correct answers tend to use more reasonable and moderate terms)

-irrelevant info outside the scope of discussion

-minor changes to info supported by the passage

-false attributions of individuals' points of view

If you know what the questions are and you can identity the above within the passage, then you can improve your score in RC as this is 50% of RC. Mast that and then the rest will fall in place.
