<p>Our team has worked for several {months on a robot for the science fair that we plan on
entering in the robotics divisions.}
A) months on a robot for the science fair that we plan on entering in the robotics divisions.
B) months on a robot that we plan to enter in the robotics division of the science fair.</p>
<p>Why is B better than A? (B is the correct answer)</p>
<p>The habitat [in which] sequoia trees grow, [extends] from southern Oregon to northern California, is [kept] damp year-round by [heavy] seasonal rains, cool coastal air, and fog.
Why isn't IN WHICH wrong? Shouldn't in be "where" because the habitat is a place?!?!</p>
<p>In A, “that we plan on entering” is incorrectly modifying science fair, and not robot.</p>
<p>The habitat [in which] sequoia trees grow, [extends] from southern Oregon to northern California, is [kept] damp year-round by [heavy] seasonal rains, cool coastal air, and fog.</p>
<p>You may be over thinking this one. It’s very doubtful that the real SAT will ever test fine points such as the perceived difference between “in which” and “where”. They sound equivalent to me. But in any case if you doubt whether or not they are the same refer to a dictionary.</p>
<p>But look at the sentence. It has an egregious error: two verbs for the same subject! “The habitat extends” and “The habitat is”. There is no conjunction to possibly make sense of this. The SAT tests for these very basic errors. So even if you don’t recall which word is used here or there, or which preposition is right or wrong focus on the basics first.</p>
<p>Try replacing “extends” with “extending”, and now the two verb problem disappears.</p>
<p>All this said I find this sentence awkward. Is it from a real SAT exam?</p>
