<p>the heat was already <em>overwhelming and lasted a week, which duration made it seem sheer torture</em></p>
<p>a) overwhelming and lasted a week, which duration made it seem</p>
<p>b) overwhelming, and because of lasting a week, it made it seem</p>
<p>c) overwhelming and lasted the duration of a week to make it to seem</p>
<p>d) overwhelming, and its lasting a week made it seem</p>
<p>e) overwhelming and, by lasting a week, making it seem</p>
<p>the explanation (CB) says that the answer is D, but then goes on to say that E is wrong because it has 2 "it"s, when it doesn't, but D does have 2 "it"s. </p>
<p>Can someone confirm the answer to this question? and why is the pronoun "which" in A unclear?</p>
