<p>Wow! Thanks a lot knowthestuff! Your explanations were really concise, comprehensible, and extremely helpful. </p>
<p>Just a few questions though:
Regarding your fourth post from the bottom about the WR question section 10 #12:
Doesn’t the possessive “its” have a clear antecedent: college? It cannot refer to the president because she is human and it cannot refer to the changes because those are plural. I thought it was very clear while reading it, which alas brought the confusion.</p>
<p>And second your first post for the Math section section 7 #16:
I know we can plug in numbers for variables to help solve problems. I usually do this to verify the answers for these types of problems but if I can’t solve the problem that’s what I do to solve it. I thought that each different variable represents a different number. By your solution, does this mean that for all future similar problems, I can plug in the same numbers for the different variables unless explicitly stated otherwise?</p>
