<p>One of the free improving sentences questions on the college board writing section reads: The revolt against Victorianism was perhaps even more marked in poetry than either fiction or drama.</p>
<p>I got this question right; the answer is "in either fiction or drama" but I was wondering, is there anything grammatically wrong with "in either fiction or in drama"?</p>
<p>For stylistic reasons, parallelism is the issue here. I would argue to say there is acutally no grammatical error in the sentence as is.</p>
<p>when two or more prepositions joined to two or more seperate ideas, you can either </p>
<ol>
<li>use the preposition in front of the first one and omit the rest
or</li>
<li>use it in front of every item</li>
</ol>
<p>so in A, B and C and in A, in B, and in C are both grammatically correct; however, for the purpose of the SAT, option 2 produces 2(1 extra in the above example) extra words and would be considered wordy. </p>
<p>If you have The Elements of Style, see Principle 19.</p>
<p>Well the original sentence is incorrect because the parallel structure requires the use of “than in _____” because of the “more marked in poetry”. At least, that was the explanation given.</p>
<p>Oh, I get it. Thanks!</p>
