In her 26 years in the forests of Gombe, Jane Goodall collected data that proved that chimpanzees exhibit the kind of curiosity so that new patterns of behavior and expression can be passed on from each one to others by imitating and practicing.

(A) exhibit the kind of curiosity so that new patterns of behavior and expression can be passed on from each one to others by imitating and practicing
(B) will exhibit the kind of curiosity so that new patterns of behavior and expression can be passed on from one to another by imitating and practicing
(C) will exhibit the kind of curiosity so that new patterns of behavior and expression can be passed on from each one to another by imitation and practice
(D) exhibit the kind of curiosity by which new patterns of behavior and expression can be passed on from each one to others by imitating and practice
(E) exhibit the kind of curiosity where new patterns of behavior and expression are passed on to others by imitation and practice

这道题是不是出错了？？答案给的是D  怎么可能 imitating和practice并列呢 我选的是B    我在网上外国论坛看原题把D就要把改为了parcticing 但是我今天做PREP原题就是这 答案给的是D
