<p>I took the 2012-2013 practice test provided by CB, and I got some writing questions wrong. But I don't understand why they are correct.</p>
<p>First, #7, section 5. The text between the asterisks is the underlined part.</p>
<p>A poetic form congenial to Robert Browning was the dramatic <em>monologue, it let him explore</em> a characters mind without the simplifications demanded by stage productions.</p>
<p>(A) monologue, it let him explore
(B) monologue, which let him explore
(C) monologue that lets him explore
(D) monologue; letting him explore
(E) monologue by letting him do exploration of</p>
<p>I picked C, but the answer is actually B. Why? Doesn't that violate subject-verb agreement (this is why I didn't pick B)?</p>
<h1>20 Section 5</h1>
<p>Most of the sediment and nutrients of the Mississippi River <em>no longer (A)</em> reach the coastal wetlands, a phenomenon that has <em>adversely (B)</em> <em>affected ©</em> <em>the regions (D)</em> ecological balance.
<em>No error (E)</em></p>
<p>I picked D, but the answer is E. What makes this sentence have no error?</p>
<h1>21 section 5</h1>
<p>Most major air pollutants cannot be seen, although
large amounts <em>of them (A)</em> <em>concentrated in (B)</em> cities
<em>are visible ©</em> <em>as (D)</em> smog. <em>No error (E)</em></p>
<p>I picked B, but the answer is E. What makes this sentence have no error?</p>
<p>It's interesting how there are two questions back-to-back that have no error. Counting these last two questions, there is a total of 8 questions on the test that have "no error" as the answer. I learned that "No error" questions come up around 3 to 4 times on a test from my SAT prep class. Should I disregard statistics related to frequency of question types when choosing an answer? To be honest, one big reason I did not pick E for those two questions was that I saw that I had answered many other questions with "No error," so I thought that those two questions must have some error.</p>
