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

During the month of May, crabs arrive on Delaware’s beaches to lay eggs. Certain shorebirds depend on these eggs for food during their annual spring migration to their northern breeding grounds. Delaware’s crab population has declined recently. This decline, however, poses no serious threat to the migrating shorebird populations: by remaining longer in Delaware, the birds will be able to eat enough crab eggs to allow them to complete their migration.
Which of the following, if true, most seriously weakens the argument?
A. No other food available to the birds on Delaware’s beaches is as nutritious and accessible as are crab eggs.
B. The decline in the number of crabs on Delaware’s beaches is due to the harvesting of crabs by humans.
C. There are more crabs on Delaware’s beaches than in any other area that the migrating birds pass through.
D. The crabs do not conceal their eggs.
E. The earlier in the season the shorebirds complete their migration, the more likely they are to breed successfully.
答案：E
