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?
下面上狗.... AA 一个啤酒厂准备进行aggressive national distribution campaign。提议的人说现在厂的产品在全国还是供不应求的状态,而且商品都是你越买不到人家就越要买,所以假如现在提高产量的话肯定能大大提高销售额。然后三年之内,这个厂应该就能成为国内领先的啤酒厂了 AI Public figure只应该谈论那些他们亲身经历过或者影响到他们自身的那些事情

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
