The analyst suggested that traders pay more attention to a broader mea

KAPLAN OFFICIAL EXPLANATION:

Without ellipsis, the final part of the sentence would read but the analyst suggested that traders not ignore standard indicators. That's surely more than we need, but the abbreviated version in the original sentence swings too far in the other direction. In the original sentence, it's not perfectly clear who should avoid ignoring indicators and the structure of the final section isn't parallel with the first. In order for it to be parallel, "not to ignore" needs to parallel that traders pay more attention since both phrases are supposed to follow from The analyst suggested. Therefore, eliminate (A) and (B) for breaking rules of parallelism; neither creates a grammatically correct conclusion to The analyst suggested. (E) creates a similar problem. Try taking out the middle of the sentence and see if it would be okay to say The analyst suggested that traders pay attention but they should still not ignore. The problem is that that traders pay attention is not parallel to they should not ignore. Of the remaining options, you can eliminate (D) for altering the meaning of the original sentence by replacing but with and. (C) remains.

An 800 test taker knows that ellipsis only works when the pieces that the abbreviated portion keeps imply the pieces it doesn't. In order forbthat to happen, the essential pieces must remain and must parallel the structure of the rest of the sentence.
