大全-19-15.     Over the last century, paleontologists have used small differences between fossil specimens to classify triceratops （三角龙）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. （上个世纪，古生物学家把fossil分为16个，这个不对的，因为其中11个用来区分来自同一个时间，同一个地方）  

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

(A) Not every species that lived in a given area is preserved as a fossil. 不是所有的都有化石，无关

(B) At least one individual of every true species of triceratops has been discovered as a fossil specimen.至少有一个种是对的。

(C) No geographical area ever supports more than three similar species at the same time. 没有地理位置可以生存3种以上，（你还11种）

(D) In many species, individuals display quite marked variation. 很多地方，个体展示很丰富，不支持（C）

(E) Differences between fossil specimens of triceratops that came from the same area are no less distinctive than differences between specimens that came from different areas.（不支持，一个地方的区分比其他的地方的区别还大）

看了大家的评论，我觉得我理解的不是很一样.

题干是说， 把这个恐龙分成了16 种是不对的， 因为其中11种是来自同一个地方同一个时间的。


我觉得题干的作者想表达的意思是： 11种来自同一个地方同一个时间，那么会不会有可能是同一个种类， 只是个体差异造成的呢？ 作者显然是认为分16种太多了


所以选项D 是支持作者反驳的， 不知道我说的对不对
