The main idea of the passage is In order to secure fair access to showers, the Yale women's crew team called attention to Title IX in an unusual way. How does the detail in bold develop the main idea?
In 1976, the highly successful women's crew team at Yale University—an all-men's school until 1969—faced a distressing situation: the boathouse still had no women's showers. After every practice session, the men enjoyed hot showers while the women went home cold and wet after a morning of vigorous rowing. The women approached school officials about this untenable situation, but nothing changed. Finally, they opted for dramatic action to focus attention on the different treatment of Yale's male and female rowing crews. They arranged a meeting with a school administrator and invited a writer and photographer from the school paper to attend. At the meeting, the team captain read an eloquent, pointed statement explaining the conditions the team had to endure without access to showers. Meanwhile, the women displayed the words "Title IX" written on their bodies, referring to a federal law banning gender discrimination in educational activities. When an article about the meeting appeared in the New York Times, the team not only got their showers but also succeeded in raising public awareness about Title IX.
