The writer ... that her book ... her hundreds of thousands of euros.

[i]The writer … that her book … her hundreds of thousands of euros.

A) doesn’t believe / has been fetching
B) won’t believe / will fetch
C) didn’t believe / would fetch
D) couldn’t believe / may fetch
E) hadn’t believed / fetched [/i]

Why A?

No reason. A, B, C, and D are all possible. I find C the expected.

Yes, I answered C too, but they key is A :S

It is a poorly written question, probably composed by a non-native speaker.

Was this question asked in a specific context, that is, was this sentence part of a story? If so, that might explain their choice of answer A.

Yes, that is a possibility.

What would it be, if framed by a native english speaker?

Mary Smith is surprised. The writer doesn’t believe that her book has been fetching her hundreds of thousand of euros, so she is going to run right over to her agent’s office tomorrow and see if it’s true!

Thanks professor. Make sense to me. What if “…fecthing hundreds or/and thousands or euros…” ?
