<p>Here we go again! The hardest part of the SAT.</p>
<p>Plants grown for<a href="A">/u</a> their flowers should be treated with<a href="B">/u</a> a low-nitrogen fertilizer because excessive nitrogen promotes<a href="C">/u</a> the growth of leaves at the expense of flowers . No error (E)</p>
<p>My gut feeling was no error, because "promotes the growth of leaves at the expense of flowers" sounded right. Why is this parallel? I'd appreciate if someone could offer a grammatical explanation.</p>
<p>Opposite to <a href="A">/u</a> most people I know, Annie, a good photographer herself, (B) actually enjoys seeing<a href="C">/u</a> the photographs that her friends take on their <a href="D">/u</a> vacations. No error (E)</p>
<p>Choice (A) sounds wrong, but I couldn't find a reason for it so I put E. The answer was A. </p>
<p>Not very particular in<a href="A">/u</a> nesting sites, (B) house wrens may nest<a href="C">/u</a> in birdhouses, mailboxes, building crevices -- even in the pockets of<a href="D">/u</a> hanging laundry. No error. (E)</p>
<p>Answer is A. No idea why.</p>
<p>Thank you in advance.</p>
