KAPLAN OFFICIAL EXPLANATION:
D
One idiom being tested here is
hope for versus
hope to. One can hope for something to happen or for a thing-hope for a peaceful resolution to the problem. One can also hope to do something-hope to travel the world one day.
In this sentence, the students want to do something: change careers. The proper idiom is
hope to. Eliminate (A) and (B). Another idiom tested here is
exchange for, so (C)'s
exchange with is wrong. (E) doesn't specify what the "drab jobs" are being exchanged for.
