同问,对于its指代PRC有疑惑 

yifengjingyus

its应该指代的是句子的逻辑主语吧 逻辑主语不是stringent rationing and planned

distribution么？

指代China三

for two decades用现在完成时

there being，错

试着解释一下吧：

A. Even though从句是一般过去时，主句是现在完成时，根据句意，两者应该在同一时期内发生，所以时态使用不对。

B. 正确。保证了even though这个表达比despite和although更强烈转折的意思，时态、数（Its vs. has）对应。

C. Despite后面一般跟名词，不加分词短语这样更复杂的形式

D. 同C。There being的用法绝对错（刘公理1-3）

E. There be在GMAT考试中只表示自然存在。

此外，Its不能指stringent rationing and planned distribution,因为主句后面用have allowed，说明其复数性质，所以只能指the People's Republic of China。
