Explain this tough passage based question

<ol>
<li>The questions posed in lines 40-42 (“But…meal?”) and lines 61-63 (“Yet…rice?”) serve to
(A) offer concrete solutions
(B) underscore particular predicaments
(C) exaggerate trivial differences
(D) introduce new problems
(E) dismiss certain options</li>
</ol>

<p>I highlighted the quotes in the passage below</p>

<p>

</p>

<p>brah i dont know what is so difficult about that question but just by glancing at the two underlined parts in a few seconds, it looks likes B no?</p>

<p>B is correct. Can you tell me why it’s not D?</p>

<p>It seems clear, even without reading anything other than highlighted sentences, that these problems have already been introduced. A quick glance back through the passage confirmed it.</p>

<p>Yes obviously for D to not be the answer the problems have to have been previously introduced. Please elaborate. Where have they been introduced before?</p>

<p>for the second part see: Baachan calls brown rice inaka food, something for peasants. Japanese see it as impure because the bran, which is refined away in white rice, darkens the grain. The stripping of the nutritious bran . . .</p>

<p>This section is telling you that brown rice is healthy and the Japanese don’t eat it</p>

<p>It is just as clear in the first part</p>

<p>Got it. Thanks.</p>

<p>Now that you understand it better find more questions of this type and keep practicing. If you understand each one after a review, you’ll be well on your way to an improved score. Good luck.</p>
