C. in their

D. in that they
are attached to a cartilage rod at the elbow rather than at

E. in their being
attached to a cartilage rod at the elbow instead of

答案为D。they难道没有指代不清的问题？我选的B，虽然B感觉指代也不怎么清楚，但我觉得可以就近指代，觉得这里的指代不清很严重，就把有they的全部排除了。

解释差异，或说明有何特别之处时，用in that比because好。见OG208

because of 后只能接名词或短语，不能加doing之类的动名词。

这题我也觉得they有点问题，但是别的实在没法选。我觉得这里they应该指代前面一种松鼠。因为后面有rather than，都是以前以后做比较。
