If i was Jennifer i would inmediatly leave the building instead of looking for the problem, i would try to stay calmed and i think i won’t wait for the students to leave the building too. Most importantly if the students caused the false alarm, fact that she could notice because of their delay on leaving the building. Then I would be worried, because I will know that my ears were seriously damaged due to the sound of the alarm, the “false alarm”, and, of course, I will be angry with the studens who sounded it. Later, I will go to the hostpital, or something like that, in order to find a cure for the ears’ problem.
