According to two teams of paleontologists, recent fossil discoveries in Pakistan show that whales, porpoises, and dolphins are more closely related to some of the oldest known even-toed ungulates--a group of hoofed mammals that today includes cows, camels, pigs, and hippos--than to any other mammals.
(A) that whales, porpoises, and dolphins are more closely related to some of the oldest known even-toed ungulates--a group of hoofed mammals that today includes cows, camels, pigs, and hippos--than
(B) that whales, porpoises, and dolphins are more closely related to some of the oldest known even-toed ungulates--a group of hoofed mammals that today include cows, camels, pigs, and hippos--as
(C) whales, porpoises, and dolphins to be more closely related to some of the oldest known even-toed ungulates--a group of hoofed mammals that today include cows, camels, pigs, and hippos--than they are
(D) whales, porpoises, and dolphins as being more closely related to some of the oldest known even-toed ungulates--a group of hoofed mammals that today includes cows, camels, pigs, and hippos--as they are
(E) whales, porpoises, and dolphins as more closely related to some of the oldest known even-toed ungulates--a group of hoofed mammals that today include cows, camels, pigs, and hippos--than
原文意思：根据一些考古学家的调查，最近的一个发现显示一些动物A这类动物更象和B这类动物有关系而不是和其他哺乳类动物有关系。
题目分析：原文more than这个联词引导了一个并列，more后面是related to且than后面也跟to any other，前后比较对应，留着。B把more和as一起用，more是“更”的意思，而as是“和。。。一样”的意思，两个词放在一起意思冲突，杀。C than后面放they are和more后面的不对应，干掉。D又是more和as一起用，不对，干掉。E than后面没有to，而more后面说的是related to，杀。A最符合more than这个对应关系，选A。
