<p>Simple question:</p>
<p>Because the parking lot was (filthy), the waterfront (had no) lifeguard, and the sand (covered) with trash, tourists (walking by) the beach realized that it was closed.</p>
<p>lol indeed. I don’t understand the sentence at all…</p>
<p>I think it is covered because of parallel structure; but I could be wrong.</p>
<p>i think it should be “was covered” instead of “covered”</p>
<p>cause of parallel structure?</p>
