conditionals

- "Can you lend me a few dollars because I forgot to bring my wallet?"
- "_______ you pay me back tomorrow."

a. Provided
b. Unless

My book gives b as the correct answer but it doesn't sound ok to me.


Thank you!!!

I agree with you. I can't make b work out to be a meaningful sentence.

Thank you!

I think it would only work out if it were:
"Not unless you pay me back tomorrow"
