in 1977, in the midwest, there was millions of dollars of destruction from a tornado that lasted seven hours.

Explanation:

To determine correct subject - verb agreement, we analyze the subject. Here, the subject related to the verb is "millions of dollars". "Millions of dollars" is a plural noun phrase (since "millions" is plural and refers to multiple dollars). In the "there be" structure, the verb should agree with the subject. So, a plural verb ("were") should be used, not the singular "was".

Answer:

A. In 1977, in the Midwest, there were millions of dollars of destruction from a tornado that lasted seven hours.
