Science reporter: In an experiment, scientists fed one group of mice an ordinary diet and fed another group a diet fortified with the microbes found in yogurt. The mice then explored a maze made up of tunnels and uncovered paths. The mice on the fortified diet ventured out of the tunnels twice as often as the other mice did, suggesting that the mice on the fortified diet felt less anxiety about being out in the open. This shows that the differences in the mice's diets affected their anxiety levels.

Which of the following, if true, would most strongly support the science reporter's conclusion?

A. In addition to having the added microbes, the fortified diet differed from the ordinary diet by having significantly fewer calories.

B. The microbes found in yogurt produce a chemical known to lower anxiety levels.

C. In a second experiment conducted to check the results of the first, the diets of the two groups of mice were switched, and then the mice ran the maze again.

D. Dietary changes can affect mice's sensitivity to light and thereby affect the strength of their preference for dark, enclosed spaces.

E. The anxiety levels of mice affect their behavior in many ways that the scientists could have easily observed during the experiment.

Recent photographs of the planet Venus reveal long lines that appear to be the result of massive streams of lava from volcanic eruptions. However, the lines cannot have originated from lava flows, since some of these lines are over l,000 miles long, and recently acquired evidence shows that the surface temperature of Venus is not high enough to allow molten lava to travel much more than 200 miles before solidifying.

For an evaluation of the argument, it would be most useful to determine whether

A. craters formed by meteor impacts on Venus could have made some of the lines shorter than they originally were

B. the photographs of Venus reveal some mountain peaks that could only have been formed by volcanic eruptions

C. there still exist active volcanoes on Venus that could cause new lava flows to occur

D. mountain ranges might have prevented lava flows from extending farther than they would have if they had not encountered such obstructions

E. at the time the lines were formed, the surface of Venus was substantially closer to the temperature at which lava melts than it is now

EE第一题应该为B
E选项：科学家很容易观察出来anxiety level。
但是原文并没有说venture out tunnels的行为就是anxiety level不同的导致的，仍然缺少一条逻辑链。所以E选项并不影响

1、现象：吃了加强餐的老鼠比普通餐的老鼠更不容易焦虑，更容易走出迷宫，原因：饮食影响老鼠的焦虑水平。
问strength
思考：果因论证，考虑加强因果联系、排除他因削弱、类比加强或单独加强原因

A：加强餐卡路里更少。不知道卡路里与焦虑得关系，无法加强。
B：加强餐里的微生物有利于减少焦虑。正确，单独加强原因。
C：另一个实验把老鼠和餐饮交换了。不知道结果，无法加强。
D：饮食变化会影响老鼠对光的敏感度，从而影响他们对暗的、封闭环境的喜爱度。实验中是open的环境，与封闭环境无关。
E：老鼠焦虑水平会影响行为，且可以被科学家观察到。无关。

选B

2、火星的温度不足以让岩浆流动超过200mile，所以long line不是岩浆形成的。
问evaluate
思考：因果论证，考虑削弱因果联系、他因削弱

A：陨石可以使line比形成时短。方向反。
B：一些山峰是由火山喷发造成的。无关。
C：现在仍然有活火山可以产生岩浆流。无关。
D：山可以使岩浆流变短，否则可以更长。方向反。
E：line形成时，火山温度更贴近岩浆融化（更高）的温度。正确，所以当时可以流更长，削弱结论。

选E
