<p>If it were
While a mother broods her eggs, she turns them daily, and sometimes twice, which kept them evenly warmed.
There would be a tense disagreement (turns/kept)</p>
<p>For the second one, I don’t know if it’s grammatically incorrect, but choice E says it more precisely and less awkwardly than choice D.</p>
<p>which is a vague pronoun. it doesnt refer to anything in the sentence.</p>
<p>in the second sentence, honestly I cant find anything wrong in D, but if you have 2 correct choices, choose the shorter one, so E is the answer</p>
<p>Yeah, I think for the second one, “all of them” is a vague pronoun as the subject is switched from “Jane Austen” to “novels” although “all of them” should be referring to Jane Austen grammatically. </p>
<p>Hopefully that made sense, I don’t really know how to explain it very well.</p>
