The network determined that seventeen commercials should be shown duri

KAPLAN OFFICIAL EXPLANATION:

The main grammatical problem in the sentence as it originally stands is should be shown Looking at the rest of the sentence, you can see that should be shown contrasts with can be expected to contain. Should is wrong because it indicates that the number of commercials per sitcom is hypothetical; it needs to be changed to will be shown or an equally declarative construction in order for the sentence to be grammatically correct. Only choices (B) and (E) make that correction. You can then eliminate (E) for changing during a half-hour sitcom to by a half-hour sitcom. The alteration changes the meaning of the original sentence and makes no sense in its own right: the sitcom can't show commercials. (B) remains.
