<p>Q1: B - “mortally killed” just doesn’t make sense, and is redundant. B removes the redundancy, but maintains proper grammar.
Q2: I’d have to see the context, but A is the only answer that makes sense to me.</p>
<p>After you claimed D was the correct answer, I read the question once more and it seems to be more logical than A–based on the context. Although A is gramatically correct (which is why I originally chose the answer), D seems to fit the permeation of the passage. </p>
<p>Thanks everyone!! Fortunately, those were the only two (out of the 75) I stumbled on. I say this because the sample questions I have do not come with the answers or answer explanations… THAT BLOWS!</p>
