Shouldn't "제 친구가 항상 공부하는데 저는 공부를 보통 안해요" also be accepted?
For the last part (... usually do not study), would this not also be acceptable? ... 보통 공부하지 않아요
I entered that in, and it was marked correct. 2019/10/3
Should a space follow 안 to separate it from 해요?
Does there have to be a full stop after 공부하는대
내 친구는 항상 공부하는데 나는 보통 공부를 안 해요 is wrong, why?
