而且D没有什么明显错误啊？




123. (30997-!-item-!-188;#058&004357)
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.

(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

even-toed ungulates--a group of hoofed mammals that today include cows, camels, pigs, and

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

这里的a group of hoofed mammals为什么用单数， hoofed mammals已经加了s，a group 的话更应该是复数了啊。。这样的话一上来就会把正确选项排除掉了TT
