<p><span style="color:#27ae60;"><span style="font-size:20px;">The Right Answers</span></span></p>
<p><strong>Blank 3:</strong> This one is the easiest to solve. We can see that there is support happening with the comma in the last sentence, so naturally, we can use the <span style="color:#8e44ad;"><strong>Math Strategy</strong></span>. On the left-hand side, we have the idea of "never perfect". This same idea should be continued on the right-hand side, so the blank should be something like "imperfect".</p>
<p>The best match for this would be <span style="color:#27ae60;">compromised</span>, since it conveys the idea of certain qualities being reduced, reflecting the idea of imperfection.</p>
<p><strong>Blanks 1 and 2:</strong> Since the first sentence tells us that the room is only suited for one type of sound, we can deduce that there will be a contrast between how different types of sounds are handled in a particular room. From this, we can form a <span style="color:#8e44ad;"><strong>Block of 4</strong></span> between Music and Speech in "spaces that are reverberant":</p>
<ul>
<li><strong>Music:</strong> best i)---------</li>
<li><strong>Speech:</strong> [less (-)] ii)---------</li>
</ul>
<p>Since the word "less" already causes a contrast, both Blank 1 and Blank 2 should be positive or negative.</p>
<p>The best fit for Blank 1 would be <span style="color:#27ae60;">appreciated</span>. This is the only positive or negative choice here. The others are neutral.</p>
<p>The best fit for Blank 2 would be <span style="color:#27ae60;">intelligible</span>. Since we chose something positive for Blank 1, we also need Blank 2 to be a positive choice. This is the only positive choice.</p>

<p><strong>Blank 1:</strong></p>
<ul>
<li><span style="color:#e74c3c;">controlled:</span> This choice contradicts the logic. The answer choice is neutral, while we need a positive or negative word for our Block of 4.</li>
<li><span style="color:#e74c3c;">employed:</span> This choice contradicts the logic. The answer choice is neutral, while we need a positive or negative word for our Block of 4.</li>
</ul>
<p><strong>Blank 2:</strong></p>
<ul>
<li><span style="color:#e74c3c;">abrasive:</span> This choice contradicts the logic. Since we chose a positive word for Blank 1, we must choose a negative word for Blank 2, as per our Block of 4 logic. So abrasive would not work.</li>
<li><span style="color:#e74c3c;">ubiquitous: </span>This choice contradicts the logic. The answer choice is neutral, while we need a positive or negative word for our Block of 4.</li>
</ul>
<p><strong>Blank 3:</strong></p>
<ul>
<li><span style="color:#e74c3c;">eliminated:</span> This choice has no evidence. There's nothing to say the sound itself would be removed, only the idea that the quality will be imperfect.</li>
<li><span style="color:#e74c3c;">considered:</span> This choice has no evidence. There's nothing suggesting that we need to think about speech and music.</li>
</ul>
