<p>How come the answer is "unvarying" as opposed to "average"?</p>
<p>Since the curves of Puerto Rico were sensual, wouldn't the "aggressive two-dimensionality" be "non-sensual", a.k.a. "average"?</p>
<p>Please help :) Any explanations for this?</p>
<p>Help with #19. Why isn't the answer A?</p>
<p>Help with #21. How come the answer is not B?</p>
<p>The online explanations simply don't help much. Thank you :)</p>
