3. Why are justice and liberty together extremely important as a citizen of
the United States? *

"... 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.
