I am a native English speaker. A Chinese roommate of mine who is an international student studying English asked me the following question:
The man who swam in the ocean drowned because he ....... to swim.
A. Hasn't learned B. hadn't learned C. wasn't learning D. didn't learn
I am leaning towards either A or D, but she says it is B because the guy died and it's double past or something which I have no idea.
What is the correct answer?
