PLEASE TELL US HOW THIS PROBLEM CAN BE ANSWERED WITHOUT THE PROPER OPTIONS.
Look for the topic/subject particle, 는/은 or 가/이.
In this case, the only option is (출입구)는.
입구 is entrance
입구 wasn't in the hints and there isn't an option to select 문이
Please explain how we answer when there is option provided. Reported
The answer is this "그 출입구는 열려 있다".
출구 = exit
입구 = entry
출입구 = doorway
열려 있다 = be (left / kept) open
열고 있다 = be opening
Can't "문이 열려요" also be used to say the door is open?
Or does it mean "the door opens?"
I think you should use a progressive tense since it's an ongoing thing. I think I saw it in another exercise.
