Among people in Tiravia who had a fatal car accident while driving, 5 percent of those under 50 years old were found to have prosinopsis, a currently untreatable eye disease that causes a gradual deterioration in peripheral vision. Yet, according to medical records, only 3 percent ofTiravians under 50 have been diagnosed with prosinopsis. Therefore, when a Tiravian driver under 50 has prosinopsis, the disease significantly increases the likelihood that the driver will have a fatal car accident.
Which of the following, if true, most seriously weakens the argument?
A.People who have prosinopsis in its later stages are generally unable to drive because of the marked deterioration in their peripheral vision caused by the disease.
B.There are reliable tests that will allow prosinopsis to be diagnosed even in its earliest stages.
C.When prosinopsis is in its early stages, its effects are detectable only by means of laboratory tests, which few Tiravians under 50 undergo.
D.Although a large majority of Tiravians who have been diagnosed with prosinopsis are over 50, many are in their 30s and 40s.
E.Prosinopsis causes no significant deterioration in a persons vision other than the deterioration in peripheral vision.
