[CR. ] GWD TN14 Q23
Because visual inspection cannot reliably distinguish certain skin
discolorations from skin cancers, dermatologists at clinics have needed to
perform tests of skin tissue taken from patients. At Westville Hospital,
dermatological diagnostic costs were reduced by the purchase of a new imaging
machine that diagnoses skin cancer in such cases as reliably as the tissue
tests do. Consequently, even though the machine is expensive, a dermatological
clinic in Westville is considering buying one to reduce diagnostic costs.
Which of the following would it be most useful for the clinic to establish in
order to make its decision?
A) Whether the visits of patients who require diagnosis of skin discolorations
tend to be shorter in duration at the clinic than at the hospital
B) Whether the principles on which the machine operates have been known to
science for a long time
C) Whether the machine at the clinic would get significantly less heavy use
than the machine at the hospital does
D) Whether in certain cases of skin discoloration, visual inspection is
sufficient to make a diagnosis of skin cancer
E) Whether hospitals in other parts of the country have purchased such
imaging machines
答案為C 好像閱讀能力問題 怎麼都不懂 拜託大家!
