1. Biologist: if reports of people's observations along the newly constructed highway are to be believed, many large herbivores such as deer and moose are grazing there. The reported numbers are about equal to our overall population estimates of the past three years, and if there are that many near the road, the animals must be even more abundant in more distant reaches of the forest. So concerns that local populations of these animals are threatened by the construction of the new highway are clearly misplaced.

Which of the following, if true, would most seriously undermine the biologist’s reasoning?

A Animals that prey on large herbivores tend not to venture anywhere near roads and cars.

B Road construction in an area reduces the availability of plants in that area to large herbivores.

C The distant reaches of the forest cover much more area than does the part of the forest visible from the new highway.

D Vacationers accustomed to encountering large herbivores make up most of the traffic on the new highway.

E The new highway was built over approximately three years.

2.Paleontologists in 1947 found a large group of fossilized skeletons of the carnivorous dinosaur Coelophysis. In the space where one Coelophysis's stomach had been, there were bones from another individual of the same species. The paleontologists concluded from this that Coelophysis was cannibalistic.

In order to evaluate the strength of the paleontologists’s argument, it would be most helpful to know which of the following?

A. How many other dinosaur species were also found mixed among the Coelophysis

B. To what extent bones from different individual Coelophysis dinosaurs were randomly jumbled together in the group of fossilized skeletons

C. What bones of other dinosaur species were also found mixed among the Coelophysis bones

D. How many other dinosaur species Coelophysis is known to have eaten

E. Whether the bones that were found in the space that had been one Coelophysis's stomach came from more than one part of the other Coelophysis's body

1.A.捕食者不在公路附近 所以公路附近的鹿多 但不代表远处的鹿更丰富（很有可能更少） 总体来说可能路边看到的就是他的总数 所以说他的数量变多了是不对的
B修路使该地区草少 不能告诉我们森林里的草多少 或是森林里的鹿多少 而且 这个地方草少了 对应的鹿也应该少 那森林里反而更多（加强了作者的说法）
C两个地方面积的比较 不能说明鹿的数量问题
D人造成交通堵塞和鹿没关系
E路修了三年 和鹿哪里多哪里少 无关

总结：想要削弱 可以想人们看到的鹿其实就是全部的了 为什么呢？——因为森林里的鹿都没有 只有路边有鹿（因为捕食者不靠近公路）
2.研究的是：这个恐龙他到底吃不吃同类？
A.其他种类的恐龙 与他吃不吃同类无关
B 来自同种的不同个体的骨骼越多 吃同类的几率越大
C.同A其他种类的恐龙和这个恐龙吃不吃同类无关
D.同AC
E.这个骨骼是不是来自于不同部位说明不了他吃不吃同类 可能一个同种恐龙不小心死在这个地方 那所有部位的骨骼都有啊
