I figured if you read every single word on RC passage including all the words on the question stems and AC, you would physically not have enough time. How in the world would one read all, answer all correct and have time left?
The word is in the conclusion so I'm not sure how subtle it would be. I think the argument and answer choice would work if the word permanent was not included in the stimulus.
@eucalyptus, yeap, 'most' worked in that case because the argument core hinged on the fact that there was a majority. Otherwise, I think it's fairly safe to assume that the word "most" is generally unnecessary in NAs.
