OFFICIAL EXPLANATION
Here’s How to Crack ItAs you read the sentence, go through your checklist. There is one pronoun (they) in the sentence, but in this case it clearly refers only to the children. Is there a modifying phrase? No. Is there a list of things or a series of actions? Not really. Are the verb tenses inconsistent? Hmm. Now we’re getting somewhere. The first verb, “maintains,” is in the present tense. So is the verb “eat.” But the third verb, “took,” which is supposed to be a parallel action with “eat,” is in the past tense.
Look at the dependent clause that is partially underlined.
…that if children eat a diet high in vitamins and took vitamin supplements…
Obviously, the two verbs are inconsistent with each other, and because only one of them is underlined, that’s the one that must be wrong. The correct sentence must have a take in it, so we can eliminate choices A and B. Choice C puts the rest of the sentence in the past tense, so scratch C. Choice D puts the rest of the sentence in the future tense. This might be acceptable, but the choice also uses the incorrect idiomatic expression likely of catching. We’ll talk more about idioms in a moment.
The correct answer to this question is E, which keeps the entire sentence in the present tense
