George: Throughout the 1980s and early 1990s, hardly anyone learned ballroom dancing. Why is it that a large number of people now take ballroom dancing lessons?

Boris: It’s because, beginning in 1995, many people learned the merengue and several related ballroom dances. Because these dances are so popular, other ballroom dances are now catching on.

Boris’s response to George is most vulnerable to criticism because it fails to

(A) show that the people who learned the merengue are the same people who are now interested in other ballroom dances
(B) explain why ballroom dancing was so unpopular before 1995
(C) relate the merengue to the forms of dancing that were more prevalent before 1995
(D) account for the beginning of the revival of interest in ballroom dancing
(E) demonstrate that all types of ballroom dancing are currently popular
