(A) and for coming up with ways to balance the budget

(E) and come up with ways to balance the budget
OFFICIAL EXPLANATION:
E. The underlined words are part of a series, so adjust your error antennae to feel out a parallelism problem. Check the grammatical construction of each element. The underlined portion contains the gerund form coming, but the other two PTA purposes are expressed in the infinitive form. All three reasons should be in the same form. Both Choices (A) and (C) use the -ing form, so they can’t be right. Choice (D) is unnecessarily wordy, so now you know the correct answer must be either Choice (B) or Choice (E). Both choices properly use the infinitive form, but Choice (B) unnecessarily repeats to and it adds information to the original sentence.
