What initiative does Conn Smythe's enlistment shortly after winning the Ontario championship exemplify?

The correct choice highlights the historical context of Conn Smythe's enlistment after winning the Ontario championship, particularly his involvement with "Pal's Battalions." This initiative allowed men to enlist in the military alongside their friends and neighbors, fostering a sense of camaraderie and community during times of war, especially during World War I. Smythe's enlistment exemplifies this movement, as it demonstrates how sports figures were often seen as role models and leaders in their communities, encouraging others to join the military for a shared cause.

In contrast, while volunteerism in sports is an important concept relating to community service and involvement, it does not specifically capture the military aspect tied to Smythe's actions. War recruitment drives do relate closely to military enlistment but do not pinpoint the unique social structure of enlisting with one's peers as Pal's Battalions emphasizes. The March of Dimes is unrelated to military service; it was primarily focused on funding medical research for polio and supporting those affected by the disease, hence not directly connected to Conn Smythe's enlistment following a championship win.
