It is a grade 8 school production play. We are doing a show for the song, Queen - Under Pressure and we have to pick one of the following groups on what we are doing for action for pressure or stress -

1. Cavemen, dinosaurs and hunters

2. Army, soldiers and war

3. Classroom, teachers and school stuff

4. Business, bosses and work

5. Hospital, doctors and patients

Please help me pick which group. So far I am stuck in a choice between:
Group 2 and 3.
