<p>In those cities in which public transportation is adequate, fewer traffic problems occur and pedestrians are rarely involved in accidents.</p>
<p>I feel like the 'in those cities in which' sounds extremely awkward and wrong for some reason, but apparently not, because it's no error. Can someone explain this grammatically?</p>
<p>Both “in which” and “where” are correct. Therefore, there is no error. Cadillac, this question type does not test one’s ability to recognize awkward syntax or diction.</p>
<p>So as long as a sentence is grammatically correct with the error ID type of questions, no matter how awkward sounding it is, it’s correct? Because in my prep books, “awkward” or “redundant” phrasing is often used as an excuse to rule out the sentence revisions.</p>
<p>Hmm it sounds strange because of the double in’s to me. I still think ‘where’ would make a lot more sense. I don’t know though, there must be some technicality we’re not seeing here.</p>
<p>I already answered the question. The proximity of the repeated “in” may make it awkward, but this question type never tests one’s ability to recognize awkward phrasing. The sentence revision questions, however, do.</p>
<p>There is no grammar rule specifically ruling this usage correct. “in which” and “where” are frequently interchangeable. Oftentimes, “in which” is the necessary logical substitution for “where,” as in “There is a book where that character gets promoted.” The term “where” refers to physical location, but the book example attempts to indicate something more abstract, and “in which” should therefore replace it, creating “There is a book in which that character gets promoted.” Unless of course, the character is a very small animal and lives between a book’s pages, where he gets promoted to a higher status in his animal society. </p>
<p>In the OP’s question, physical location is to what the sentence intends to refer, and both choices therefore work.</p>
