那MM觉得it除了可以指代the comet还能指代什么呢？

我总觉得前面没有东西突然出来一it有指代不明的错误...

GMAT句子中常见it 出现在前半句，然后在后半句中具体指出it 所指代的对象。例：OG108 ---- Reporting that one of its many problems had been the recent extended sales slump in women’s apparel, the seven-store retailer said it would start a three-month liquidation sale in all of its stores.

又一例类似的句子：大全92题 ----- Although it had been partially destroyed, the archaeologists were able to infer  from what remained of the inscription that the priest Zonainos was buried in the crypt.

各位 我想总结一下我的理解, 看是不是正确. 这样以后做类似的题目就不用再错了.
A.C.D.E 错. 与后逻辑主语"astronomers" 不搭配
B. "IT" 如果在句子前半句, 优先指代全句主语. 如果有出入, 例如这句话的主语是复数, 则去指代宾语. 但如果出现两个单数的宾语, 就是指代错误.

我想问如果主语和宾语都是单数,会构成指代不明吗?

请指教
