<p>The President A(has designated) Senator Frank B(as) one of the Congressmen who C(are going) to attend the conference D(on) nuclear waste disposal. E(No error)</p>
<p>I clearly thought the answer should be C. Since the subject in this case seemed to me like "one of the Congressmen" and so the verb should be "is going."</p>
<h1>Then when I looked at the answers, it said E. No error?!</h1>
<p>I got really confused when I checked the answer to this one.</p>
<p>The fire officials A(attributed) the high casualty rate to the fact that not one of the B(more than) two thousand rooms in the hotel C(were equipped) with sprinklers D(or) smoke detectors. E(No error)</p>
<h1>And so I thought the same thing; the subject is "one of the more than..." I put C down as the answer and that was correct when I checked my answer. The explanation in the back says "Error in subject-verb agreement. Not one of the more than two thousand rooms was equipped with sprinklers." That was the exact reason why I thought C was wrong.</h1>
<p>So for the first sentence is the answer in the book wrong or am I missing something? Thanks in advance=]</p>
<p>I'm so glad you asked this, because I also answered C for both and was surprised by the answer Barron's provided. I'm terrible at grammar so I just thought I was wrong and they don't explain it, they just say "Sentence is correct". I think the answer should be C.</p>
<p>The congressmen are the ones who are "going to attend the conference". Senator Frank isn't going alone. There is a group of congressmen who are being designated to go, not just one. Frank is being placed in the group with "congressmen"</p>
<p>the difference is in the presence of the relative pronoun "who" in the first sentence--"who are going" is a verb phrase that modifies the noun "congressmen," which in turn is the object of the preposition "of." so the entire prepositional phrase is "of the congressman who are going [etc]."</p>
<p>in the second sentence, the prepositional phrase is "of the more than two thousand rooms in the hotel," and the verb "*were (was)" goes with the noun "one." if the second sentence read this way:</p>
<p>"The fire officials A(attributed) the high casualty rate to the fact that not one of the B(more than) two thousand rooms in the hotel THAT C(were equipped) with sprinklers D(or) smoke detectors had been inspected to make sure the safety features were working."</p>
<p>then the capitalized "that" would serve the same function as the "who" in the first sentence, and the sentence would be correct as written. the relative pronoun in the prepositional phrase changes the structure of the phrase so that the verb goes with the plural noun.</p>
<p>this is yet another reason to use only CB questions. i don't recall seeing this point of grammar in a real SAT question (i could be wrong, but it definitely doesn't come up often).</p>
