Recently documented examples of neurogenesis, the production of new brain cells, include the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that learn new songs.
(A) the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that
(B) mice whose brains grow when they are placed in a stimulating environment or canaries whose neurons increase when they
(C) mice's brains that grow when they are placed in a stimulating environment or canaries' neurons that increase when they
(D) the brain growth in mice when placed in a stimulating environment or the increase in canaries' neurons when they
(E) brain growth in mice that are placed in a stimulating environment or an increase in neurons in canaries that
(A) the brain…无法与the production of…平衡；growing使用错误，应该用grow的名词形式growth来换，increasing应该用increase替换；介系词结构when placed无論是修饰主句的主词还是所修饰动词(include)的逻辑主词，该结构都是修饰的documented examples，而从逻辑意思上看，when placed应该修饰mice，因此when placed修饰对象错误。
(D) when placed修饰documented examples，导致逻辑意思错误，代词they就近指代neurons，导致逻辑意思错误
(E) 正确， brain growth in mice和an increase in neurons in canaries很好的作为了the production of
请问A和D中红色的逻辑主语怎么会是documented examples呢？请大家帮帮忙啦！！！
因为：状语从句的省略形式在句首时，其逻辑主语等于主句主语；如果在句尾或者句中，其逻辑主语优先等于它所修饰的动词的逻辑主语 - by 白勇
虽然知道用逻辑做语法很重要，可原文选项都这么老长读到E的时候都晕菜哩。赫赫，谢谢楼上两位咯！
