Answer: B) In 1977, in the Midwest, there were millions of dollars of destruction from a tornado that lasted seven hours.
Explanation: Subject-verb agreement means the subject and verb must have the same number (both singular or both plural). From the given options, the one that has the correct subject-verb agreement, is the corresponding to option B, because the subject of the sentence is "millions of dollars" which is a plural subject, therefore, the verb should be in plural form (as we can see, in option B the verb is "were").
