Choice C – This choice has verb tense error. Element 2 uses past perfect tense. Whenever past perfect tense is used, there should be a related event in simple past tense to indicate the intended sequencing of event. In this sentence there is no such event and hence use of past perfect tense is incorrect. Furthermore, this choice appears to be wordy. Two relative pronouns referring to same noun – growth seems wordy.
they, their, it都是完整指代，即指代包含了被指对象的所有修饰成分， that， one都是核心指代。
搬运自曼哈顿论坛：D的错误，首先，如果这个时间段已经结束，那么就不能用现在完成时； B中，你不能在这个结构中 使用that,因为that of(或者that+其他介词)必须有完全平行的结构，如果后一半说的是that during 10000 years,那么前一半必须是the growth of... during...(或其他介词，如before or after来代替during);此外from when是没有问题的，因为从句以from when开头是一个很完美的名词性从句；但是呢，the beginning of agriculture毫无疑问比when agriculture begin好（因为一个actual noun总是比一个名词从句更好一些）
b错在哪？
from when是不对的

E：what it did for中的it指代的the growth of the global economy，但从逻辑意思上看应该指global economy。错误选项。
C) that指代错误，表达罗嗦不清晰;过去完成时态错误，应该用过去时态。
