13.   On the Great Plains, nineteenth-century settlers used mud and grass to build their homes, doing it without timber and nails.

(A) settlers used mud and grass to build their homes, doing it without

(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（D）

(E) settlers’ homes were built of mud and grass, making do without

dingdang gg, 不知道想要问什莫，我猜你可能不知道make do 得意思。make do 是说勉强凑或着用的意思。希望有用。

谢谢gg夸奖。 我觉得句子的结构是: settlers used ...making..., 这样making 是同used一个级别的（逻辑意思错误，其实想表达的是同build一个级别的东西）， them也就是指mud and grass(指代错误），还有making them while not having是否有wordy and redundant得错误？因为while not having 可以用without 表达的。见笑！

同意MM的解释!　再次感谢！
