Which of the following is one consequence faced by children at the Mission School?

The consequence of being locked in the basement reflects a historical reality faced by many children at Mission Schools. These institutions often employed harsh disciplinary measures aimed at enforcing conformity and suppressing cultural identity. This specific consequence symbolizes the extreme methods used to control and isolate students who resisted the imposed education system.

In contrast, spending time outside, assigning extra chores, and giving presentations are more common activities that might be found within any educational institution and aren't linked to punitive measures in the same way. Thus, while those activities could be part of a school's routine, they do not align with the severe consequences that were characteristic of the environment in Mission Schools. The focus on imprisonment serves to highlight the oppressive nature of such facilities and their attempts to erase the cultural identities of Indigenous children.
