<p>These questions were from the blue book - I am simply stumpped. Please someone help to explain what the right answer is and why. Thanks</p>

<ol>
<li>The survey (showed that) most shoppers who drive prefer the mall (more than) downown stores (simply because) finding parking is (less difficult) at the mall. (NO ERROR)</li>
</ol>

<ul>
<li>The error here is (more than), since saying "prefer" and "more than" is redundant. It should be replaced by "over," as it is idiomatically correct to prefer something over something else.</li>
</ul>

<ol>
<li>Proffessor Chen repeated (her point that) the hero, if (given) the chance (to relive) the moment would choose to (do it). (NO ERROR)</li>
</ol>

<ul>
<li>I think (do it) is the error here. I can't give you a grammatic rule for this one (other than to say it's another idiom), but I think "do so" is what it should be replaced with.</li>
</ul>

<ol>
<li>(Today) a medical doctor must often (make a choice) between (engaging in) private practice (or) engaging in research. (NO ERROR)</li>
</ol>

<ul>
<li>The error here is (Today), which should be replaced with "Nowadays." The reason for this is something to do with "often" -- perhaps because it implies a period of time, rather than a single day -- but, again, I don't know the exact grammatical rule.</li>
</ul>

<p>I hope that helps. Hopefully somebody will be able to confirm what I've said...</p>

<p>I thought 29 was (or) because you choose "between this and that," not "between this or that."</p>

<p>I think zach is correct for all of them except 29. The error is in the word "or". The rule is "between...and..." as opposed to "or".</p>

<p>Thanks Zach.....you got 18 and 26 correct, but you did not get 29 correct. Anyone else?</p>

<p>I believe the answer for 18 is letter B ( more than). Note that the word "prefer" is already used to show that the shoppers favor the mall, so the word " more" is not necessary. "more" should be substituted for "rather".</p>

<p>For 26, the answer is letter D. Observe how akward "do it" it sounds; It should be "do so" since the hero would do the action of relieving the moment.</p>

<p>For 29, the answer--i believe-- is letter "or". it should be "and"</p>

<p>I am not an expert, thus there is a possibility that i may be inaccurate.Neverhteless, i have been scoring high in the Wr.</p>

<p>For the most part, I agree with zach. However, my opinion differs on a few things.</p>

<ol>
<li><p>Don't you prefer something "to" something else, instead of "over" it?</p></li>
<li><p>I agree with zach completely. I don't know exactly WHY it is an error, but this is one of those instances where it just "sounds wrong."</p></li>
<li><p>The error in this sentence is "or." You choose between something "and" something else, not something "and" something else.</p></li>
</ol>

<p>Hm, I didn't notice that, since "Today" and "often" seemed awkward to me -- I didn't pay attention to the end of the sentence.</p>

<p>"Today" is probably just a throw off, though. I'm not sure if there's any grammatical rule that says you can't say that. You're probably right about "or" being the error.</p>

<p>EDIT:</p>

<p>"18. Don't you prefer something "to" something else, instead of "over" it?"</p>

<p>I think it's correct either way, at least in this case. (I'm by no means positive, though.)</p>
