<p>Naomi and Charles will represent Ammonton High in the debating <contest, there=“” work=“” in=“” this=“” having=“” been=“” excellent=“” year.=“”>
The answer is D: contest, for their work as public speakers has been excellent this year.
Why is it has not have?</contest,></p>
<p>The answer is “has” because “their work” is singular (even though “they” is plural) - work is singular.</p>
<p>thank you very much</p>
<p>Also, as it’s written, there’s a comma splice between “contest” and “*their.”</p>
