老prep sc18题---正确答案句子疑问求助~~~！！！

Thymeling

Bluegrass musician Bill Monroe, whose repertory, views on musical collaboration, and vocal style influenced generations of bluegress artists, also inspried many musicians, including Elvis Presley and Jerry Garcia, whose music was differed significantly from his own.
whose是非限定定语从句，为什么谓语inspried前还要加also，这样去掉whose从句，句子就是Bluegrass musician Bill Monroe also inspried many musicians。了。这个also在语义逻辑上不就很奇怪了吗？？？

你的逻辑是对的，但是你把句子简化以后再读，还是觉得需要also，毕竟是重复的意思。
eg. Mark, who built the first social network website, also built the first music website.

Thymeling

这个句子是正解句子
