Identifying Sentence Errors
Correct Answer: B
This sentence illustrates a subject-verb agreement error. The subject, "Sponsors of the Olympic Games who bought advertising time on United States television," is plural; the word underlined at choice B should be "include," to match the number of the subject. The correct sentence reads: Sponsors of the Olympic Games who bought advertising time on United States television include at least a dozen international firms whose names are familiar to American consumers.
