So I am practicing for the GRE - my weakness is the verbal section, I think. My vocabulary could use improvement, so I've been working on studying new words. But despite that, even when I know the words in the question, there is one "type" of question that always stumps me. Namely, I have difficulty when I can see more than one "correct" choice for a sentence completion question. To give an example, take a look at the following question (select two answers): As some skilled in vocabulary may already know, the proposed answers are [a] and [e]. Sure. Those answers fill in the blanks in such a way that the sentence makes sense. But what really gets me is that I have a hard time being SURE that these are the "correct" choices, because other options also fit the blanks in a way that makes sense to me. For example, "Reporters described the storm's effect on voter turnout as benign" appears natural, and so does "Reporters described the storm's effect on voter turnout as inconsequential" also has a similar meaning. Looking at this sentence alone, both selecting [a] and [e] as a pair and and [c] as a pair seem completely correct to me. I really don't understand how we can say for sure that reporters would say that a storm was "harmful" to voter turnout, but they would not say that it was "benign" to voter turnout. It seems totally dependent upon the situation that is being described... --- I don't know if I've described the question "type" that I'm having trouble with sufficiently. But I really don't understand all that well how we can say for sure that, in the example above, [a] and [e] are the correct choices when this seems only one possibility. Again, ( & [c] seem like another grammatically correct pair, which could totally make sense in some contexts... Can someone please help me?
