※ 引述《henry77ha (fsdae)》之铭言：
: 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
: 答案为C 好像阅读能力问题 怎么都不懂 拜托大家!
大意大概是说 在医院使用皮肤诊疗机器，
可确实的减少诊断皮肤癌的 cost。
即使此机器很贵，诊所也觉得应该可以买一台。
(C) Whether the machine at the clinic would get significantly
less heavy use than the machine at the hospital does
在诊所使用此机器，会不会比在医院使用的次数少很多。

谢谢! (C)的逻辑真跳跃 要想到这个环节啊!
