狒狒36

36. Sometimes when their trainer gives the hand signal for “Do something creative together” two dolphins circle a pool in tandem and then leap through the air simultaneously. On the other occasions, the same signal elicits synchronized backward swims or tail-waving. These behaviors are not simply learned responses to a given stimulus. Rather, dolphins are capable of higher cognitive functions that may include the use of language and forethought.
Which one of the following, if true, most strengthens the argument?
(A) Mammals have some resemblance to one another with respect to bodily function and brain structure.
(B) The dolphins often exhibit complex new responses to the hand signal.
(C) The dolphins are given food incentives as part of their training.
(D) Dolphins do not interact with humans the way they interact with one another.
(E) Some of the behaviors mentioned are exhibited by dolphins in their natural habitat
题目的结论是海豚的行为是基于更强的识别功能比如语言和forethought，而不是通过利用刺激物训练达到的
答案为B，是如何增强了这个论述的呢？
我选的是E，如果他们在自然环境中就有上述功能的话，那不是说明了他们是通过自动识别，而非通过食物一类的刺激物才产生的吗？

文章说的是海豚对一个手势可以作出不同的反应，说明海豚不是简单的对刺

激物的条件反射式的学习，而是更什么的云云。ACD都可以排除，B的意思是说，

海豚对手势经常另出机杼，展示复杂的新动作，这是对文章的重述，E的意思

是某些行为出自自然的习惯，这只能说明非由刺激产生，但不能说明通过识别

产生。

i thought D is reasonable too.

It says in the passage that "dolphin... may... use of language...", that's what D is saying.

what do you think??

文章并没有提到海豚之间的交流方式, 所以D不能说明任何问题. 除非你假设它们之间的通信是通过对刺激的反应.
