<p>Recent studies indicate that eating chocolate and other sweets neither causes nor aggravates acne.</p>
<p>The sentence is apparently NE but I thought "neither causes nor aggravates" is wrong...</p>
<p>Can somebody explain?</p>
<p>neither and nor always go together</p>
<p>Oh, I know neither and nor, it’s the verbs that I’m referring to. I thought it should be neither cause nor aggravate because everything else is plural…</p>
<p>The gerund ‘eating’ and causes/aggravates go together, so I think this one should be no error. =]</p>
<p>
</p>
<p>It should not be “cause/aggravate” because “eating chocolate and other sweets” is singular.</p>
