On the great plains, nineteeth century settlers used mud and grass to build their homes, doing it without timber and nails.
B settlers used mud and grass to build their homes, did it without
C settlers used mud and grass to build their homes,making them while not having
D settlers used mud and grass to build their homes,making do without
E settlers' homes used mud and grass to build their homes,making do without

答案是D，想不明白呀，我自己先的是A

选项是否正确一靠语意，二靠划线外的部分的提示

A did it without ，请问it指代谁？当然是homes，怎能用it?杀
B 用的也是it，E动作发起者不对，都杀
也就剩C和D了。唯一区别是them while not having和do without
我虽然对D的说法不熟悉，也没见过，觉得挺狗屎的，但好在C比D还屎。使杀C留D

我水平也不高，仅供参考

A: doing引导的看着像是伴随状语或是结果状语，但是意思上根本解释不通。
B: used和did两个动词之间没有连词。
C: 由主动句改为被动句了，这是罗嗦的说法。
E: 主语应该是settlers，该选项把主语改成settlers’ homes了，根据4:1原则，排除
