whereas的用法：used to make a statement that describes how two people, groups, etc., are different
再看一些例句： Some of these species have flourished, whereas others have struggled.
Whereas many people have supported the proposal, others have opposed it very strongly.
He has brown eyes whereas his children have green eyes.
看完这些例句，再看回选项A，是不是觉得A这个句子写的非常的优美，遵循了parallelism。（虽然whereas引导的句子并不一定要平行）
其余选项的错误分别是：
B.and连接的是两个independent clause, 而and的左边是whereas引导的dependent clause；for adults还可以错误的修饰“language areas overlap...”，变得illogical
C.when使用不当。it seems to suggest that "these languages" occupy distinct area when they are learned by an adult and not at other times !
D.in adults错误的修饰了each language,这是illogical的 ； occupied时态错误
E.独立主格，无法用and连接一个独立主格和一个independent clause； and也改变了原句中这种对比的意味
