Here is my question:
_________you have no key, you will have to get back before I go out.
A. Although B. Provided C. As D. Unless

I opt "B. Provided" which means "if": If you have no key, you will have to....". However, the answer is "C. As". Is it because "As" here means "Because"? Because you have no key, you will have to..."

Thanks for enlightening me.

    "As" would be my choice.

    The reason:

    You need an introductory that means "because". Of all these "as" is the only one with that meaning.
