PREP08 177 对一个句子中出现两个by不解

177.
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 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 one to another by imitation and practice
E.        exhibit the kind of curiosity where new patterns of behavior and expression are passed on to others by imitation and practice
正解为D
我对整个题的思路没有异议。
但是D选项中，the kind of curiosity by which new patterns.....can be passed on.....by imitation and practice。
我对两个by有点不理解。把句子整理顺之后就是，new patterns....can be passed on from ...to ...by imitation and practice, and by the kind of curiosity.如果按照原来句子的话这两个by不是重叠了么？passed on既by curiosity又by imitation and practice，如果没有连词and来平行的话岂不是很诡异？
请牛牛指教

这个id有吗

第一个by是相当于定语从句的介词前提，第二个by是定语从句里引导方式状语，并不冲突

额...没懂.....
第一个介词是提前，which是定语从句的引导词，但在句子结构中是名词,具体指代curiosity
那么by curiosity, new patterns.... can be passed on ....by imitation and practice。虽然说是定语从句，但是这几个词本身还是在修饰passed on。
我的思路好像有点钻牛角尖了。。。看到一样的结构不平行不舒服斯基。。。

我觉得 句子整体大意是猩猩们传递行为靠三种方式 by imitation and practice,and by curiosity  根据平行 by也不能省略

所以这句话是把其中一个平行元素放进主句作为核心句意，然后用从句解释。
soga~~ 非常感谢~
