OE
“Otherwise” suggests that Gottlieb did not find Steinbeck’s political views admirable. “Adolescent disaffection” suggests that Gottlieb found Steinbeck’s views in some sense immature, so look for negative words that mean something like unsophisticated. “Naïve” and “callow” are the best options. “Perspicacious” and “keen” both suggest insight, nearly opposite of what the sentence suggests. “Disinterested” is a tricky word here. It most commonly means unbiased, though it can also mean not interested (two very different meanings). Neither option makes a great sentence here, but just as important, none of the other answer choices has a similar meaning to either definition. “Contemptible” is negative, but with no suggestion of immaturity—make sure to use the clues provided without adding your own ideas.
