<p>This is question 17 on page 538:</p>
<p>No one "objects to" [A] his company, even though he has made insulting remarks "about"** "almost every"[C]member of the "group, and when"[D] he is a remarkably witty man. "no error"[E]</p>
<p>The parts in quotations are the underlined parts and the choices are right next to them.</p>
<p>It's D, first of all your re-writing of the question is wrong because there is no 'and' after group, second of all, that part of the sentence makes no sense because it turns into a run-on and is totally incoherent. Just read it to yourself a couple times: No one objects to his company, even though he has made insulting remarks about almost every member of the group, when he is a remarkably witty man. That last clause doesn't make sense because the comma makes the sentence a run on/incoherent.</p>
