GMAT Critical Reasoning (CR) | Re: In the past 20 year, there has been a significant increase

in gmat, most of time, when encountering assumption, or strengthen, or weaken questions, ones do not need to read the question stem because these kinds of questions already imply the target to attack. That is, the conclusion and the main premise.
Rarely, in too complex arguments, or mixing-type question, the question stem will be helpful to find the answer.
