<p>An economical and efficient recycling center is accessible to the public, responsive to community needs, and complies with current federal regulations governing waste disposal. </p>
<p>Answer: No Error
My Question: How is this sentence parallel? “accessible” and" responsive" are adjectives. “complies” is a verb.</p>
<p>The answer is compliant. What book are you using?</p>
<p>oh its definitely compliant. the book is wrong. like seriously.</p>
<p>This is from collegeboard’s official online course.</p>
<p>Is this improving sentences or identifying errors?</p>
<p>It’s grammatically correct, so “No Answer” is right if it’s in the Identifying Errors section. However, if it was in the Improving Sentences section, then most likely, it would be changed to “compliant” because parallel structure like that is preferred in mature writing.</p>
<p>^Probably the best answer. If it were identifying errors, however, I don’t think they would have compliant as an answer choice.</p>
<p>Identifying Sentence Errors section was where the sentence came from (parts of the sentence were underlined, where I had to choose what parts of the underlined choices was the incorrect form)</p>
<p>So, what happens if I come across a sentence like this? It is unfair for collegeboard to only sometimes use the rule.</p>
<p>Voytek clearly explained what I wanted to say! 
In ISE section, you don’t necessarily have to improve because you have to IDENTIFY ERRORS, not to IMPROVE :)</p>
<p>I think the sentence was
An economical and efficient recycling center is accessible to the public, responsive to community needs, and comply with current federal regulations governing waste disposal.
The CB corrects the sentence this way:
An economical and efficient recycling center is accessible to the public, responsive to community needs, and complies with current federal regulations governing waste disposal.
That’s bad - the parallel structure is corrupted.
But who cares - it’s enough to notice that comply is incorrect.
Correct me if I am wrong.</p>
<p>@gcf101 The “who cares” is me LOL. If collegeboard people THINK this is the way to correct a sentence and I think it isn’t, then I am going to encounter problems in the real test. What if the answer is not obvious, and the sentence is not parallel? Since collegeboard is saying that a non-parellel structure is still grammatically correct, I might incorrectly bubble in the wrong choice. </p>
<p>When practicing, I don’t care if I get the right answer as much as to understand the reasoning behind the answer.</p>
<p>To everybody else, this is identifying error, but “complies” was only underlined. This is the one single error in the sentence, so I am not trying to improve the sentence as a whole. Only this one word is ungrammatically constructed.</p>
