<p>Hi, I’m studying for the Critical Reading section of SAT, and I have some questions that I couldn’t understand in the Official SAT Study Guide (aka Blue Book). I would really appreciate it if you would give detailed explanations for my question!</p>
<p>On pg. 523 Question 19.
(((( the corresponding passage for this question can be found in pg. 522 on the following link:
<a href=“The Official SAT Study Guide - College Entrance Examination Board - Google 도서”>The Official SAT Study Guide - College Entrance Examination Board - Google 도서;

<ol>
<li>Lines 55-57 (“Since…sleepiness”) primarily serve to
(A) introduce a lighthearted digression
(B) provide a transition to a new subject
(C) offer evidence in support of a prior claim
(D) acknowledge a drawback to an approach
(E) return the discussion to a problem mentioned earlier in the passage</li>
</ol>
<p>I chose B, because although the sleepiness was mentioned at the beginning of the passage, the paragraph starting with line 55 actually does introduce a new idea, about people’s self-rating scale and an alternated method to determine how sleepy a person is. But the answer was E. Oh, and by the way, what is the ‘problem’ in choice E referring to, exactly?</p>
<p>Your help will be much appreciated. Thanks! :)</p>
