The passage suggests that neuroscientists would most likely consider Shaker to be which of the following?
这道题上来看了题目，是问neuroscientists对shaker的看法，然后回忆当初看的文章里，只讲了ethologists对shaker的看法，然后就没辙了= = 后来听答疑录音，说是根据文章最后一句，有个in contrast，后面讲了ethologists对某种基因的看法，由此推出前面应该讲的是neuroscientists对shaker的看法，并与之相反，因此选了A。 但是再仔细看文章可以发现，in contrast前面讲的是ethologists对shaker的看法，后面还是这拨人对另一种基因period的看法，所以还是不知道这道题目该怎么做……麻烦老师了！

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?
