In what way do the children demonstrate leadership?

The choice that highlights how the children demonstrate leadership is that they motivate one another and take initiative. Throughout "The Mysterious Benedict Society," the children often find themselves in situations where they must think creatively, collaborate, and lead one another in their efforts to solve problems. Their ability to encourage each other fosters a team environment where ideas can flourish, showcasing their leadership skills.

In addition, taking initiative illustrates their proactive nature; they do not wait for instructions but instead act on their instincts and capabilities. These qualities are essential in a leadership context, as they underscore a willingness to take charge and inspire others to engage in collective efforts.

The other options focus on actions that either rely on external authority figures, such as adults or Mr. Benedict, or lean towards a more passive form of participation, which do not fully encapsulate the essence of leadership demonstrated by the children.
