A lot of my classmates participated in scouts when they were younger but dropped out before junior high. But I've found that scouting gets better and better the longer you stay involved. Older kids get to go on longer camping trips and learn more interesting skills. We also get to work with younger scouts, teaching them what we know and helping them earn badges. Those who achieve the highest level of scouting are eligible for college scholarships. I plan to stay involved in scouts until graduate high school. How does the detail "Those who achieve the highest level of scouting are eligible for college scholarships" best support the central idea that scouting gets even better with age?

A. It describes one of the benefits of staying involved in scouting,

B. It proves the claim that people who participate in scouting are smart.

C. It suggests scouts can earn badges for attending college and learning new skills.

D. It notes that high school graduates can no longer be scouts but can be leaders.
