While the volunteer rates of teenagers remained quite low in 1974 and 1989, we find that volunteering rates for individuals aged 16 to 19 actually doubled between 1989 and [2005] — to a rate that exceeds the national volunteer rate …. Increased enthusiasm for volunteering among today’s young people is reflected in other research as well. For example, the Higher Education Research Institute’s (HERI) found an all-time high in the percentage of first-year college students who indicated that there was a high probability that they would volunteer or participate in community service sometime during their college careers. The Corporation’s College Students Helping America report recently highlighted a 20 percent increase in the number of college students volunteering between 2002 and 2005, while the University of Michigan’s Monitoring the Future study also finds a rising trend in volunteering among teens. —Corporation for National and Community Service, “Volunteer Growth in America: A Review of Trends Since 1974” List two details from the article that support the argument for requiring one hundred hours of community service to graduate high school.

"... the Higher Education Research Institute’s (HERI) found an all-time high in the percentage of first-year college students who indicated that there was a high probability that they would volunteer or participate in community service sometime during their college careers."

"... University of Michigan’s Monitoring the Future study also finds a rising trend in volunteering among teens."

Explanation:

The two details of the article shown above, can support the argument of requiring a hundred hours of community service to graduate from high school. This is because these details show that the requirement of volunteering work in secondary education influences young people to participate in voluntary activities again and this is a good thing for society, since volunteer work is able to help the State to solve some social problems.

In short, the requirement of 100 hours of community service to graduate from high school, trains young people willing to help society.
