When drivers are deprived of sleep there are definite behavioral changes, such as slower responses to stimuli and a reduced abil
ity to concentrate, but people's self-awareness of these changes is poor. Most drivers think they can tell when they are about to fall asleep, but they cannot. Each of the following illustrates the principle that the passage illustrates EXCEPT:
(A) People who have been drinking alcohol are not good judges of whether they are too drunk to drive.
(B) Elementary school students who dislike arithmetic are not good judges of whether multiplication tables should be included in the school's curriculum.
(C) Industrial workers who have just been exposed to noxious fumes are not good judges of whether they should keep working.
(D) People who have just donated blood and have become faint are not good judges of whether they are ready to walk out of the facility.
(E) People who are being treated for schizophrenia are not good judges of whether they should continue their medical treatments
