Laos has a land area老题求解释

—看千行的时候发现的老题，OG13 43
43. Laos has a landarea about the same as Great Britain but only four million inpopulation, where many aremembers of hill tribes ensconced in the virtually inaccessible mountain valleysof the north.
—
—(A) about the same asGreat Britain but only four million in population, where many—
—(B) of about the samesize as Great Britain is, but in Laos there is a population of only fourmillion, and many—
—(C) that is about thesame size as Great Britain’s land area, but in Laos with a population of onlyfour million people, many of them—
—(D) comparable to thesize of Great Britain, but only four million in population, and many—
—(E) comparable tothat of Great Britain but a population of only four million people, many ofwhom


卡在了CE之间，看了Ron，OG的解释，仍对C中them指代four million people抱有幻想，我认为C 的结构是Lao has..., but...many of them are....，but连接两个句子不算run on sentence，them指代前面的four million people。求解释这样理解有什么问题？？


以下是Ron的解释

Q： I can not figure out the sentense structure. Say, "a population of only 4 million people" after "but" is used for what?
the "but" creates parallelism between the 2 nouns describing things that laos has.
with choice (e), the sentence reads as follows:laos has a land area comparable to that of Great Britain but a population of only 4 million people, many of whom...
so, basically, laos has X but Y, where X and Y show some kind of contrast with each other. (the contrast here is apparent, as great britain certainly has more than four million inhabitants.)

千行里关于many of whom 和many of which的解释：

"many of whom" is not a subject pronoun; it's a relative pronoun. it has EXACTLY the same grammar as plural "which".
if you understand whyi adopted two dogs, which weigh approximately 100 pounds eachori adopted two dogs, each of which weighs approximately 100 poundsis not a run-on sentence, then you also understand why (e) is not a run-on sentence.
by contrast, if the sentence had contained "many of them", then it would be a run-on.
so:*i adopted two dogs, they weigh approximately 100 pounds each is a run-on sentence (--> incorrect). for the same reason,*i adopted two dogs, each of them weighs approximately 100 poundsand*... a population of only 4 million people, many of them are members of hill tribes...would also be run-on sentences (--> incorrect).

当时这个题我也不会做，
后来做题发现
but, while后面只要和前面主语一样的话，后面的主语可以省略而且去掉 ...

我明白E中but是对的，但C中but看成连接两个完整句子是不对的吗？如果可以，那them不能指代people是因为them不能指代immediate precedent的rule吗？

C里面but那个句子没有主语谓语，but是要加句子的。

in laos是个方位介词。

but后面是句子呀，many of them are....

不过with a population看起来更像修饰laos的而不是这些人

many of them和who差不错，是个从句不是句子

哦要是单独句子的话them指代的对象应该在本句里，而不是上句里，大概这个意思？
