<p>The question is:</p>
<p>(Neither) (A) the catalog nor the museum guide (explained) (B) the technical aspects of Picasso's paintings (thoroughly enough) (C) (to satisfy) (D) inquisitive art students. </p>
<p>The answer was supposed to be E, but I chose B. My reason was that since the sentence was a generalization, referring to all inquisitive art students rather than a specific group, it should have been in the simple present tense. Thus, I though B should have read explains and not explained. </p>
<p>If it had said the inquisitive art student, I would understand why this would have been no error. </p>
<p>Can someone tell me if i'm wrong, and, if so, why?</p>
