<p>This is from May Sunday 2009 QAS</p>
<p>Unlike the open plains on which prides, or groups, of lions live, tigers are solitary animals that live and hunt in forests.</p>
<p>B. Unlike the prides, or groups, of lions living on open plains
D. Whereas lions live in prides, or groups, on open plains.</p>
<p>D is the correct answer. I can see why D is correct, but why B is wrong?
Is it because the subject in B is lions living on open plains? So this is a parallelism issue?</p>
