1. 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 canarie
neurons when they
(E) brain growth in mice that are placed in a stimulating environment or an increase in neurons in
canaries that


此题正确答案是E，我明白为什么。但是有两个小疑问，第一：A选项prep解释说the brain...无法与the production of...平行。他们两个需要平行吗。第二：我做这道题是这么考虑的，我认为E选项brain growth in mice that 与 an increase in neurons in canaries that 平行，因为有连词or，所以这么做出来的。这个想法对吗？请NN们帮个忙····解释一下

这么做这道题是没有问题的，但是较为严格来讲是有关系的，稍微来分析一下：include这个词表示了前后两者的关系：A，include B and C——说明BC应该同属于A，是A的子集，因此brain（大脑）本身不属于production（总量），但是brain growth（脑细胞的增长量）则是production（总量）的一部分。可能prep解释说的比较模糊，才导致有点难理解
