8-18：

Although partially destroyed, the archaeologists were able to infer from what reamined of the inscription that the priest Zonainos was buried in the crypt.

a) although partially destroyed, the archaeologists were able to infer

b) although partially destroyed, the archaeologists had inferred,

c)although it had beenpartially destroyed, the archaeologits were able to infer,

key to the answer is C, explanation is that C 补全了ALGHOUGH 从句恢复了IT 作主语（指INSCRIPTION）。本句中FROM 短语前置，THAT从名才是INFER 的宾语。

问题是：IT所指代的主语怎么可以离它那么远又是怎样一种解释IT可以做这样的指代呢属于哪一种用法呢？？

THANKS

子句中it一般优先指代主句单数成分，而主句中仅有inscription是单数，另一个单数crypt不是主句成分，而是修饰成分。
