Some United States psychologists have concluded that one specific set of parental behaviors toward children always signifies acceptance and a second set always signifies rejection, for there is remarkable agreement among investigators about the maternal bahviors designated as indicative of these parental attitudes.
The conclusion of the psychologists mentioned above logically depends on the assumption that
A) most maternal bahviors have been interpreted as conveying either acceptance or rejection.
B) the maternal behaviors indicating acceptance or rejection are exhibited by father as well.
C).....
D).....
E).....
答案是B. 但是我认为题目中的原因（最后一句话for there is.....)不是已经表明了B的意思吗？为什么B是假设呢？答案A不是挺好吗？ 刚好把结论（第一句话）和原因联系起来。
