지난달에 학생은 어디에 갔어요?
Honestly, the 지난달에 and 학생은 can be switched around colloquially.
How to know when to switch the student and time? Sometimes i get it right and sometimes wrong....
@duolinguo can we can any answer over here regarding the order of words?
지난달에 and 어디에, two location markers is ok? Or is one redundant? Or do you need both?
Is it wrong to have a space between 지난 and 달?
