"누가 상자를 보낼 것입니까?" marked as wrong. The basic Korean word order is subject-object-verb!
Is it generally subject-object-verb, or only for questions? I answered it as you had stated.
"누가 상자를 보낼 것입니까?" is what I say colloquially. Why is this marked wrong?
Agree. And it even sounds more natural.
It was marked correct for me as of 2-6-2018
Only "것입니까" is accepted as a correct answer for this question .lower formality levels should also be accepted, they are accpeted for other questions.. the incosistency in this course is frustrating.
