Hello,
Daksh20. I have written a detailed post on how I break down RC passages and answer choices,
here. The same sorts of trap answers you find in CR questions tend to pop up in RC answer sets as well: overreaching language (e.g., must, always, cannot); reversals (the opposite of what you want); off-topic choices (or inferences that cannot be made); meaningless quantifying language (e.g., some). I like to make two passes of the answer choices. In the first, I am looking for obvious red-light answers. If I do not understand something, it becomes an automatic yellow-light answer so that I do not waste time. With practice, you can typically spot at least two red-light answers. With whatever is left, you want to look to attack any weakness in the language, whether it simply does not match what the question is asking for or it does not align with what the passage presents.
I hope that helps. It should be enough to get you started anyway. If you have further questions, feel free to ask. Good luck with your studies.
