标题: prep2-49, from when

Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture to 1950.

(A) Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture

(B) Since 1990 the growth of the global economy has been more than that during 10,000 years, from when agriculture began

(C) The growth of the global economy since 1990 exceeds that which had been for 10,000 years from the beginning of agriculture

(D) The growth of the global economy since 1990 exceeds what it has been for 10,000 years, from when agriculture began

(E) The growth of the global economy since 1990 exceeds what it did for the 10,000 years from the beginning of agriculture

答案是A

我有两个问题呢

第一个就是from when 为什么错呢？为什么from后面一定要跟名词，还有就是when agriculture began 不可以充当名词吗？比如说when you come here really matters a lot. 这里面的when you come here不就是作为句子主语吗？当然就是名词了

第二个就是from the beginning of agriculture to 1950 两个都是过去的时间，应该用过去完成时呀？这里为什么要用过去时呢？

from the beginning of agriculture to 1950 是修饰10,000 years 的,决定时态的是 during the 10,000 years

求问：到底有没有from和 when连用的用法呢？？

如同GWD17-Q19

Regardless of their form or function, all aerodynamically enhanced, curved objects made for throwing have been called boomerangs by non-Australians even since 1788, when Europeans saw Dharug-speaking men tossing “bumariny” in the area later known as Sydney.

A.   Regardless of their form or function, all aerodynamically enhanced, curved objects made for throwing have been called boomerangs by non-Australians ever since 1788,

B.   Regardless of their form or function, any aerodynamically enhanced, curved object made for throwing has been called a boomerang by non-Australians ever since 1788,

C.   Ever since 1788, non-Australians have called all aerodynamically enhanced, curved objects made for throwing boomerangs, regardless of their form or function, from

D.   Ever since 1788, any aerodynamically enhanced, curved object made for throwing has been called a boomerang by non-Australians, regardless of its form or function, from

E.   Non-Australians have called all aerodynamically enhanced, curved objects made for throwing boomerangs ever since 1788, regardless of their form or function, from

答案有说是A也有说E的，关键在于from和when能否连用呢？？

这个题prep里有，选A，因为when是修饰前面的时间的，修饰词应该紧跟修饰对象。
但是我对于“from when用法错误”这种说法表示怀疑……不知道这种说法是不是真的有问题……
