I realized that the villages who had gathered around me were arguing as to _____should have the honor of receiving me as a guest in their house.答案是填who，但前面有介词to为什么不能用whom呢？

因为as to 是介词短语，后面是个宾语从句，从句中缺主语，所以只能是who

俊狼猎英团队为您解答。 个人觉得，这是个病句。as to 后面加一个decide 或者把as to改为about才是对，即I realized that the villages who had gathered around me were arguing as to 【decide】who should have the honor of receiving me as a guest in their house。或I realized that the villages who had gathered around me were 【arguing about】 who should have the honor of receiving me as a guest in their house。分述如下： 1.第一种改法，as to do sth做目的状语，arguing 的目的是为了decide 一个receive“ me”的家庭；who should have the honour of receiving me。。。是宾语从句，做动词decide的宾语； 2，第二种改法，argue about 是个短语，“为。。。事争论”的意思。
