<p>The "Mayan Riviera," which extends down to eastern coast of Mexico, [has may hidden] caves, one of which is larger [than the size of] Monaca</p>
<p>The answer was [than the size of]</p>
<p>I knew it was wrong because it's redundant to say "larger than the size of" but wth it says "has MAY hidden." I figured it was just a typo lol. Did they do that on the actual SATs..? since this was a released exam..</p>

<p>3.
Brazil is not only the most populous of the twelve south american countries but also the largest [in area]</p>
