Why did the children question Mr. Benedict's decision to include Constance in the mission?

The children questioned Mr. Benedict's decision to include Constance in the mission primarily because of her behavior traits; specifically, she was perceived as clumsy and cranky. These characteristics raised concerns among the children about her ability to contribute effectively to a challenging mission. Clumsiness can indicate a lack of physical coordination, which might hinder the group's success during critical moments, while being cranky can imply difficulties with teamwork and collaboration, essential features for a successful mission. The children were looking for a balanced team where every member could reliably carry out their responsibilities, and they worried that Constance might not meet those expectations given her behavioral tendencies.
