求助OG13 SC72 , 关于what的用法 谢谢

72. His studies of ice-polished rocks in his Alpine homeland, far outside the range of present-day glaciers, led Louis Agassiz in 1837 to propose the concept of an age in which great ice sheets had existed in now currently temperate areas.

(A) in which great ice sheets had existed in now currently temperate areas
(B) in which great ice sheets existed in what are now temperate areas
(C) when great ice sheets existed where there were areas now temperate

(D) when great ice sheets had existed in current temperate area

(E) when great ice sheets existed in areas now that are temperate


1、请问B项中的what的用法怎么理解？
2、看到OG中的解释，似乎E的错误只是now的位置错了。如果E项改为“when great ice sheets existed in areas that are now temperate"，正确吗？

what是宾语从句；E选项按你说的那样改的话应该没错。

感觉B 的what宾语从句好别扭 自己不知道如何恰当表达 但是感觉读不通

另外作者说的E  改成that 那不就是 areas that  are XX temperature了   地区和温度对应。

请教大牛啊

为了儿砸拼命冲

问一下NN，B选项what 改成where可以吗？改成
ice shits existed in where are now temperate areas.可以吗？
