<p>(A: Determined) to make a name (B: for herself) (C: as a writer) of short stories, Helen never submits anything to an editor until (D: revising) it several times. (E: No error)</p>
<p>The answer is D of course, but I wanted to know the precise way of correcting it.</p>
<p>The most logical and easiest correction for me was this:</p>
<p>Determined to make a name for herself as a writer of short stories, Helen never submits anything to an editor until she has revised it several times.</p>
<p>But would this work as well:</p>
<p>Determined to make a name for herself as a writer of short stories, Helen never submits anything to an editor until having revised it several times. ?</p>
<p>(Personally, it seems wrong)</p>

<p>The Roman poet Virgil is (A: highly esteemed) today for his epic poem, The Aeneid, (B: yet) on his deathbed he himself (C: sought) to prevent its publication on the grounds (D: of not being) sufficiently polished. (E: No error)</p>
<p>The answer is D. My rationale was that "not being sufficiently polished" hangs on the subject "Virgil," which is wrong. So, I think it should be "... on the grounds of ITS not being sufficiently polished" to show that the subject of this phrase is "his epic poem" or "it."</p>
<p>Thanx in advance :)</p>
