求教！！一个关于有连词的run-on句子的问题——prep08 186

MyrticeTAN

SVO,but + 介宾结构，SVO.这样的句子是run-on句子么？？？？

prep08语法笔记里186题
Laos has a land area about the same as Great Britain but only 4 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 4 million in population, where many
B. of about the same size as Great Britain is, but in Laos there is a population of only 4 million, and many
C. that is about the same size as Great Britain's land area, but in Laos with a population of only 4 million people, many of them
D. comparable to the size of Great Britain, but only 4 million in population, and many
E. comparable to that of Great Britain but a population of only 4 million people, many of whom

对C的解释是
C. 定语从句wordy，用形容词短语就可以，更加简洁，而且意思没减少；land area的重复使用也累赘；population为抽象名词，them指代不明；but后面不成句子，无法与前面平行； with a population of only 4 million限定性修饰Laos错误，显得有很多个Laos。

但是BUT后面不是有many of them are……的完整句子么？不能是后面两句是一个整体吗？

等待NN解答~谢谢
