<p>Hi,
In an identifying error question, question is:
1) In those cities, in which, public transportation is (blah blah blah).
Never mind the rest of sentence. the answer is E(sentence is correct). but isn't the use of "in which",in context, is wrong because "cities" refers to place and thus, the correct word should be "where"(not "in which").<br>
Plz help.SAT is approaching.</p>
<p>They are both correct, at least in this context. I’m assuming you accidentally added the comma after “in which” since it is not correct.</p>
<p>*No comma. what do u mean by “at least in this context”? When can we use “in which” for “where”?</p>
<p>I don’t think there is a general rule. Phrases that use prepositions like IN or ON tend to be very idiomatic. So you would have equivalents like these:</p>
<p>the bench where David sat -> the bench on which David sat
the field where David sat -> the field in which David sat
The store where David bought ice cream -> the store at which David bought ice cream</p>
<p>There are probably other exceptions. People learn these rules through usage, not books.</p>
