<p><span style="font-size:20px;"><span style="color:#8e44ad;">Pairing Up</span></span></p>
<p>First things first. We use the <strong><span style="color:#8e44ad;">Pairing Strategy</span></strong> to identify any synonym pairs among the six answer choices. There are usually two, sometimes one, sometimes three. We call the "triple pair" the <a href="https://www.youtube.com/watch?v=I0Sxxibos-I" target="_blank">Great White Buffalo</a>.</p>
<ul>
<li><strong>Pair 1</strong>: comprehensive/inclusive</li>
<li><strong>Pair 2</strong>: universal/ubiquitous</li>
<li><strong>Maybe Pair: </strong>fundamental/significant
<ul>
<li>They're not REALLY a pair but they can both mean "important."</li>
</ul>
</li>
</ul>
<p><span style="font-size:20px;"><span style="color:#27ae60;">The Right Answer</span></span></p>
<p>Use <strong><span style="color:#8e44ad;">Math Strategy</span></strong> here. The phrases "and" and "almost as" indicate that the two ideas support each other. The first states that RNA is "common to all living beings." To maintain that idea, we guess a word like "common" or "widespread" for the blank.</p>
<p>The best match for this guess is the pair <span style="color:#27ae60;">universal/ubiquitous</span>.</p>
<p><span style="font-size:20px;"><span style="color:#e74c3c;">The Wrong Answers</span></span></p>
<ul>
<li><span style="color:#e74c3c;">comprehensive/inclusive</span>: We have <strong>no evidence</strong> whether RNA or DNA includes anything.</li>
<li><span style="color:#e74c3c;">fundamental/significant</span>: Setting aside the fact these two are not REALLY a pair, we have <strong>no evidence</strong> that RNA and DNA are important. I mean clearly they are. But the sentence does not explicitly mention their importance.</li>
</ul>
