Answer:
Stanley Milgram and Philip Zimbardo were both social psychologists who conducted famous experiments on obedience to authority and the power of situational factors on behavior.
In this situation, where the teacher is commanding the student to eat a cupcake or be expelled from school, both Milgram and Zimbardo would likely argue that the student's behavior is being strongly influenced by the authority figure and the situation.
Milgram's famous experiment on obedience to authority demonstrated that people are often willing to obey authority figures even when it goes against their own conscience. Zimbardo's Stanford prison experiment showed how the power of the situation can shape people's behavior and attitudes.
Both Milgram and Zimbardo would likely argue that the student in this situation is experiencing pressure to conform to the demands of the authority figure, and that the authority figure has a great deal of power over the student's behavior. They would also likely argue that the situation itself, in which the student's academic future is at stake, is contributing to the student's compliance with the teacher's commands.
Overall, both Milgram and Zimbardo would likely view this situation as an example of the power of authority and situational factors on behavior, and would caution against blindly following authority without questioning its legitimacy or ethical implications.
