还是。。。。我贴一下吧：
Yellow jackets number among the 900 or so species of the world’s social wasps, wasps living in a highly cooperative and organized society where they consist almost entirely of females—the queen and her sterile female workers.
A. A.wasps living in a highly cooperative and organized society where they consist almost entirely of
B. B.wasps that live in a highly cooperative and organized society consisting almost entirely of
C. C.which means they live in a highly cooperative and organized society, almost all
D. D.which means that their society is highly cooperative, organized, and it is almost entirely
E. E.living in a society that is highly cooperative, organized, and it consists of almost all
很明显，CD中的which是指代前面一句话，排除！！A中they指代错误，E中and无对应平行结构，并且it代词不可指代介短中的名词（society），所以it无指代对象。。。。
B，其实是同位语结构N，N that V。。。。
