1. Read the paragraph below. Then answer the question.

(4) Rich parents, however, are glad to show off their wealth by supporting such expensive occasions. (5) Secondly, proms encourage destructive forms of social competition. (6) Teenagers get caught up in worrying about who has the best-looking date, who spends most on a dress, or who arrives in a rented limousine. (7) And finally, proms often turn into excuses for underage drinking-and-driving excursions. Which sentence is not relevant support for the argument that high-school proms should be discontinued?

a. Sentence 2
