<p>Can someone explain this question to me? I know the answer is B but i am still not sure how to tackle it in the future. Thanks.</p>

<p>What is the subject of the sentence? In this case it is "listening". That is a singular subject so it requires a singular verb. "sharpens" is singular while "sharpen" is plural. That is what makes B correct.</p>

<p>They are testing subject/verb agreement.</p>

<p>^^ well said. and answer D makes the sentence too convoluted.</p>

<p>I don’t think the answer makes sense to me because of this: “…sharpens children’s awareness of and…”. The word “of” is to be followed by something else that is not “and”, isn’t it?</p>

<p>In this case, the object of the prepositional phrase is ‘the sounds’. The answer choice written correctly because it has a compound predicate, each with a different prepositional phrase. Thus, it’s sharpening ‘awareness of the sounds’ as well as ‘appreciation for the sounds’.</p>

<p>When the phrases require different function words (prepositions in this case), you can’t omit either: “awareness of” “appreciation for”. Omitting “of” would mean “awareness for”, which is non-idiomatic.</p>
