Physician: Goliath Pharmaceutical Company has claimed that the recent increase in the number of diagnosed cases of Disease X shows that the disease is increasing in virulence. This is a questionable argument, just as it would be incorrect to claim that our increased success rate in treating patients with Disease X is due to the disease becoming less virulent. The real cause of both increases is a newly introduced screening process that reduces misdiagnoses of patients infected with the Disease X pathogen.

The Physician’s statements, if accurate, provide the most support for which of the following as a conclusion?


(A) The new screening procedure is the reason that more people are requesting to be tested for Disease X.
(B) It is not possible to determine that a patient has Disease X without using the new screening process.
(C) The increase in diagnosed cases of Disease X is proportional to the increase in the number of clinics utilizing the new screening procedure.
(D) The new screening process occasionally diagnoses patients with Disease X when they are actually suffering from another illness.
(E) The increase in the number of diagnosed cases of Disease X is not due to an increase in the disease’s virulence.
