23. GWD17-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

请NN解释下这道题的正确选项C，不明白为什么，题目中没有提到hospital啊~，这题排除法能选出C来，但是实在不理解~求解释

提干中先说了一个hospital用成像仪器NB又省诊断成本。  尽管这东西贵，小诊所也要搞一个类似的仪器。

c： NB仪器在小诊所能派上那么大用场么？
