请教feifei蓝皮书逻辑249题

Over the last century,paleontologists have used small differences between fossil specimens to classify triceratops into sixteen species. This classification is unjustified, however, since the specimens used to distinguish eleven of the species come from animals that lived in the same area at the same time.

Which of the following , if true, would enable the conclusion of the argument to be properly drawn?

A. Not every species that lived in a given area is preserved as a fossil.

B.At least one individual of every true species of triceratops has been discovered as a fossil specimen.

C.No greographical area ever supports more than three similar species at the same time.

D.In many species, individuals display quite marked variation.

E.Differences between fossil specimens of triceratops that came from the same area are no less distinctive that differences between specimens that came from different areas.

谁能解释一下答案为何选c。 谢谢！！

题目是:从the specimens used to distinguish eleven of the species come from animals that lived in the same area at the same time推出This classification is unjustified

所以C讲的是没有地方能存在三种相似的物种,可以算是题目的一个假设吧

因为题目中否定掉那个理论的是由于所有化石都在same area，所以找一个support也必须在location上考虑
