Question

A class of students are sitting a 3 hour exam. During the exam, the teacher is relaxed and sits at her desk monitoring the students. The students are all well behaved during the exam. Suddenly, the teacher jumps up and waves her hands around in the air. She then proceeds to sit down and continue her relaxing demeanor. The students continue to take the exam and seem unperturbed. Can you explain the teacher’s sudden change in behavior?

Answer 1

Answer:

Quite a mind-bending question...

There can be many possibilities, but I think that this one suits the most -

There were some people outside the exam room who were making a lot of noise. They were disturbing the class, so the teacher jumped up suddenly and waved her hands around. This way, without saying anything which might disturb the class, she could communicate to the people outside to go away.

Hope this helps :D
