Sometimes whentheir trainer gives the hand signal for “Do something creative together” twodolphins circle a pool in tandem and then leap through the air simultaneously.On the other occasions, the same signal elicits synchronized backward swims ortail-waving. Thesebehaviors are not simply learned responses to a given stimulus. Rather,dolphins are capable of higher cognitive functions that may include the use oflanguage and forethought.
Which one of thefollowing, if true, most strengthens the argument?
(A) Mammals havesome resemblance to one another with respect to bodily function and brainstructure.
(B)The dolphins often exhibit complex new responses to the hand signal.
(C) The dolphinsare given food incentives as part of their training.
(D) Dolphins do not interact with humans the way theyinteract with one another.
(E) Some of the behaviorsmentioned are exhibited by dolphins in their natural habitat

关键是黄字部分不太明白，也不知道为啥会选B呢、。？

嘿嘿！俺来look look啦！
黄色字体应该是说，海豚这些行为不是对刺激物的反应，也就是不是靠刺激物就能够刺激的。
所以B说海豚对手势敏感，正好加强了观点：dolphins are capable of higher cognitive functions
不知解释清楚了没，自己是这样理解的！

所以这里存在的一个潜在假设就是：如果海豚有simply learned responses to a given stimulus，就不是capable of higher cognitive functions？

这个应该不用理吧！只要是加强了观点的就可以啊！
