Which sentence has the correct subject-verb agreement? in 1977, in the midwest, there was millions of dollars of destruction from a tornado that lasted seven hours. in 1977, in the midwest, there were millions of dollars of destruction from a tornado that lasted seven hours.

 The correct answer is the second one: "In 1977, in the Midwest, there were millions of dollars of destruction from a tornado that lasted seven hours".

Explanation:

     The reason why the second sentence is correct is that "were" is the past plural of verb to be "are". In this sentence, we have the third person of plural (millions of dollars) and that's the reason we must to use "were" instead of "was".
