<p>A dispute has arisen between two competing stores, each of which sells mainly clothing, furniture and jewelry. </p>
<p>Why is it 'sells' not 'selling'? Thanks</p>
<p>Do u have the May 2013 QAS</p>
<p>It’s because using ‘selling’ would destroy the subject-verb agreement due to the tense change. </p>
<p>I think you thought it was ‘selling’ because you wanted to have parallelism and saw ‘clothing’. Read the sentence again and you will notice that parallelism is not needed for sells.</p>
<p>I see it now thanks. And Mitcho I’m not sure if that question is from The May 2013 SAT sorry</p>
