A Japanese student told me that when she chose "job" in the sentence below her teacher corrected her and said that "work" is the correct one.
However difficult it may be, I decided to do the _____(work, job).
But I don't really understand why either of them would be wrong. I can understand that depending on the context one of the two might be more appropriate but there is no way of checking that since, as far as I know, no other information is given.
What does everyone think about this?
