For securing a recruitment star, which action must be completed by the explorer?

To secure a recruitment star, an explorer must successfully recruit another explorer who then serves for a period of six months. This demonstrates the explorer's ability to engage with and bring in new members, which is a critical aspect of fostering growth within the program. The recruitment process emphasizes the importance of leadership, mentorship, and community building within the Explorer program. By helping to introduce and integrate a new explorer, the individual also showcases their commitment to the program's values and their role within the organization.

The focus on recruiting and ensuring the newcomer’s service duration highlights the importance of sustained involvement and contribution to the Explorer program, rather than merely fulfilling a one-time action or attending events. The other actions, while beneficial to personal development and the program, do not directly fulfill the criteria for obtaining a recruitment star.
