资料题：Which of the following statements is NOT true（　）?

A Fire Drill is to put it mildly, an inconvenient exercise at the best of times.A Fire Drill at 2:00 in the morning in terrible weather condition, like the one we had on Thursday night-Friday morning last, is incomparably more inconvenient.This is why I am writing this note to thank you all most sincerely for your excellent cooperation and the spirit with which you endured the inconvenience.A Fire Drill is not an idle exercise.It is an extremely serious one and can in fact save lives in the long run.Last week's Fire Dill has already revealed a number of important things regarding fire precautions in the Residence Hall.For instance, there seem to exist a number of"dead spots" in the Hall, namely, the two rooms in Purser House and some rooms in the Bottom Corridor.l have no reason to doubt that residents from these areas could not hear the alarm.I shall request an immediate examination of this problem.I should, also, remind you that it is a requirement that Fire Drills are regularly carried out(at least two in every one year) and each resident is made fully aware of this and obliged to take part.All residents must take fire precautions with the seriousness they deserve. Failure to do so can result in heavy fines and expulsion from the Hall.Thank you again for your cooperation.
