真的不明白，求助 为什么是这种逻辑？

1 63. When hypnotized subjects are told that they are deaf and are then asked whether they can hear the hypnotist,
they reply, "No." Some theorists try to explain this result by arguing that the selves of hypnotized subjects are
dissociated into separate parts, and that the part that is deaf is dissociated from the part that replies.
Which of the following challenges indicates the most serious weakness in the attempted explanation
described above?
(A)    Why does the part that replies not answer, "Yes"?
(B)    Why are the observed facts in need of any special explanation?
(C)    Why do the subjects appear to accept the hypnotist's suggestion that they are deaf?
(D)    Why do hypnotized subjects all respond the same way in the situation described?
(E)    Why are the separate parts of the self the same for all subjects?

 为什么是A , 不是 D ？


2 59.  In order to withstand tidal currents, juvenile horseshoe crabs frequently burrow in the sand. Such burrowing
discourages barnacles from clinging to their shells. When fully grown, however, the crabs can readily withstand
tidal currents without burrowing, and thus they acquire substantial populations of barnacles. Surprisingly, in
areas where tidal currents are very weak, juvenile horseshoe crabs are found not to have significant barnacle
populations, even though they seldom burrow.
Which of the following, if true, most helps to explain the surprising finding?
(A)    Tidal currents do not themselves dislodge barnacles from the shells of horseshoe crabs.
(B)    Barnacles most readily attach themselves to horseshoe crabs in areas where tidal currents are weakest.
(C)    The strength of the tidal currents in a given location varies widely over the course of a day.
(D)    A very large barnacle population can significantly decrease the ability of a horseshoe crab to find food.
(E)    Until they are fully grown, horseshoe crabs shed their shells and grow new ones several times a year.

" E "  很勉强的对吧。。。

A is right. Since the deaf part and the replying part are dissociated from each other, we can deduce the part that replies is not deaf.  Thus, when answering the question "Can you hear me?", they should reply "Yes!"

D is wrong because if the hearing part and the deaft part are separated, all subjects can give a uniformed answer to the same question.  This is in accordance to the theorist hypothesis.  For example, if they all answer "Yes," the hypothesis holds. So the fact that the answers are uniformed does not weaken the argument.
