<p>Most of the books (around) this old house (smell of) mildew, and if you pick one up, you will find that the spine (has deteriorated) and (their covers have) rotted. </p>

<p>The answer in this question is D. Can someone give a technical explanation for this? </p>

<p>Quincy took Dan to Derek's home (for a visit), (never imagining) that five years (would pass) before (seeing) Derek again.</p>

<p>I thought it was no error, but it is actually D...I do not understand this answer one bit...</p>

<p>Thanks in advance!</p>

<li><p>Pronoun number error. The pronoun must agree with “one,” but it’s a plural (“their”) instead, so it’s wrong.</p></li>
<li><p>Modifier. It should say “before he saw,” because otherwise “seeing” is modifying “five years,” as if to suggest the years would pass before the years got a chance to see Derek again. Lame, I know.</p></li>
