Laos has a land area about the same as Great Britain but only four million in population, where many are
members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.
(A) about the same as Great Britain but only four million in population, where many
(B) of about the same size as Great Britain is, but in Laos there is a population of only four million, and many
(C) that is about the same size as Great Britain’s land area, but in Laos with a population of only four million people, many of them
(D) comparable to the size of Great Britain, but only four million in population, and many
(E) comparable to that of Great Britain but a population of only four million people, many of whom

正确答案是e 但是亲们我想问问c 的them 为何就会指代不明。。全文上下就只有four million people是复数。所以them 就只会指代它啊。
还有看到曼哈顿的一则语法
（2）一般所有格代词只能指代所有格名词，不能指代主格和宾格。
EG: Wrong: The board is investigating several executives' compensation packages in order to
determine how much may have been improperly awarded to THEM.
这里them本想指代executives但是这里面executives是以所有格executives’ compensation pachages的形势出现的，所以不能指代。
Right: The board is investigating the compensation packages of several executives in order to determine how much THEY may have been improperly awarded.
为什么最后right的句子 they就可以理所当然的指代executives 而不会是of前的packages呢

原谅小妹对这方面知识掌握的还不 是很牢固
我不太懂一般所有格代词只能指代所有格名词，不能指代主格和宾格。这句话的意思。
