So or although?
I was asked to fill in the gap with a suitable conjunction
She ate a lot of food __________ she was not hungry.
A. although
B. so
C. because
D. and
I don't know whether the answer is A or B?
The answer depends on context. Specifically, was 'she' not hungry before or after she ate the food?
If before, the answer would be B. Otherwise, it would be A.
However, D would also be grammatically correct (but, it does sound unnatural when you say it in your mind).
