OE
The colon indicates that the second half of the sentence will explain the frst. What is being explained is an analogy between United States politics and a pendulum, so it follows that the second half of the sentence shows how momentum in politics swings back and forth. Blank (iii) must be flled with a word that describes this seesawing effect; “reversed” does so. “Augmented” instead suggests momentum that builds upon itself, while “institutionalized” would characterize change that once made is difcult to undo, so neither of those choices ft. Blanks (i) and (ii) then must be flled with a pair of choices whose contrast explains why reversals in political momentum happen. “Grow complacent” and “redouble” do this, suggesting that the motivation of partisans on both sides of an issue is affected in opposite ways by a victory for either side. For Blank (i), “become even more focused” suggests that other victories for the winning side would follow the initial one, while “consider new possibilities” implies an expansion rather than a reversal of a political agenda. For Blank (ii), neither “abandon” nor “defend” suggests the political will that could lead to the reversal of a defeat.
Thus the correct answer is grow complacent (Choice B), redouble (Choice E), and reversed (Choice G).
