<p>The question goes as follows:</p>
<p>Which of the following is the best version of the underlined portion of sentences 8 and 9?</p>
<p>In the process Lou Hoover designed for her two young sons a portable crib. It would remain stableduring the rocking of a ship</p>
<p>A) crib so that it would remain stable
B) crib, and it would remain stable
C) crib that nevertheless remained stable
D) crib that would remain stable
E) crib. It was designed to remain stable</p>
<p>I know the answer is D, but I think A could as well. =/</p>
<p>D. A implies that a crib must be portable for it to remain stable.</p>
<p>(In the process) Lou Hoover designed (for her two sons) a portable crib </p>
<p>in the parentheses are prepositional phrases. With those cut out, the skeleton of the sentence reads “Lou Hoover designed a portable crib” … [so that it would remain stable] doesn’t make sense because there’s no “it” in the sentence. Yes, you can infer that it’s the “crib,” but only after reading the original sentence. Also, “so” is used to explain something, and the beginning phrase makes no indication that an explanation is coming.</p>
