A bomb had rendered the outside world uninhabitable except for one bunker that could sustain four people. As an assignment, students had to consider the supplies and each person's characteristics to decide which four would be spared in the bunker, while the others would be sent to their deaths. While the assignment was meant to encourage critical thinking, the student believes it is difficult to think critically in a group setting as the focus becomes pleasing others and reaching a group decision, rather than making an individual conclusion.
