<p><span style="color:#8e44ad;"><span style="font-size:20px;">Pairing Up</span></span></p>
<p>First things first. We use the <span style="color:#8e44ad;"><strong>Pairing Strategy</strong></span> to identify any synonym pairs among the six answer choices.</p>
<ul>
<li><strong>Pair 1:</strong> inscrutable/uninformative (both mean we can't understand anything useful)</li>
</ul>
<p>There's only one pair here, so we can eliminate the other answer choices: <span style="color:#e74c3c;"><s>astonishing</s></span>, <span style="color:#e74c3c;"><s>disordered</s></span>, <span style="color:#e74c3c;"><s>harmless</s></span>, and <span style="color:#e74c3c;"><s>revealing</s></span>.</p>
<p><span style="color:#27ae60;"><span style="font-size:20px;">The Right Answer</span></span></p>
<p>We can use Math Strategy to figure out the blank. There is a contrast happening with the "but"; on the right-hand side, the idea is that "dreams tell us much", so the left-hand side should convey the opposite idea. The Blank should be something like "doesn't tell us much".</p>
<p>The best (and only) match for this is the pair <span style="color:#27ae60;">inscrutable/uninformative</span>.</p>
