1、这个实验样本是否能够代表普罗大众(而不是因为他们本身就很容易得X病)
2、D
3、During salmon spawning season, the bears that avoid the salmon streams are typically smaller and less aggressive than those that frequent such streams.

Day 69
1.        吃什么都得的病
说的是一个实验,被分成两组来研究disease X--那两组人是被观察研究的,(disease X确实是题目中该病的名称,不是我编的),跟踪了两组人,发现两组都没有感染disease X; 但有一组好像 diet变化什么的;另一组没有变化;结论忘记了。但觉得这题不难,无关的选项很容易辨认。
问weaken
选项有:(1)他们吃的食物里,有其他导致这种疾病的东西。
(2)减肥的人的体重下降10% 和什么8磅之类的说法(应该是无关)。
(3)whether the group is demographically representative
(4)有一个干扰项跟寂静上的正确选项很像,就是说样本的number

两组人做实验,一组节食一组不节食,N年后都得了diseaseX, 所以节不节食都会导致X
C 样本是否有代表性


2.        杀虫剂BF
Certainly, pesticides can adversely affect the environment in localities distant from where the pesticide has actually been used. Nevertheless, regulation of pesticide use should not take place at the national level but at the local level. It is in the areas where pesticides are actually applied that they have their most serious effects. Just how serious these effects depend on local conditions such as climate, soil type, and water supply. And local officials are much more likely than national legislators to be truly knowledgeable about such local conditions.
In the argument given, the two boldface portions play which of the following roles?  
A. The first provides support for the conclusion of the argument; the second states that conclusion.
B. The first states the conclusion of the argument; the second provides support for that conclusion.
C. The first identifies grounds for a potential objection to the conclusion of the argument; the second states that conclusion.
D. The first identifies grounds for a potential objection to the conclusion of the argument; the second provides support for that conclusion.
E. Each provides support for the conclusion of the argument.

D
先说pesticide有不好的effect对离它使用地远的地方。但是,管制不应该在national level,
然后讲了严重程度取决于local的条件,所以local official 比 national更了解情况。



3.        熊和三文鱼的故事
狗熊与三文鱼的就是说狗熊最爱吃三文鱼,但是在三文鱼产卵的季节即使是最凶最大的熊,它们也会drive away 小鱼,加强

熊仔每年三文鱼产卵时不吃

1.        吃什么都得的病

C: 暂无
P: 不论diet改不改变,两组人都没有感染disease x
削弱:
(1)     食物里有导致这种疾病的东西,但是两组人都没得病,与本题P相悖。
(2)     与体重无关。
(3)     Group没有代表性的话,那研究结果就没有意义,可以削弱
(4)     数量或许无关,具体看结论是什么。

2.        杀虫剂BF

1:现象   转折,2:结论 – 3 – 4 – 5

全文的C在第二句,与第一句呈转折关系。第一个boldface描述了一个现象或者结果,第二个boldface是主C的support。选择D。

3.        熊和三文鱼的故事
C:熊赶走小鱼不吃,只吃大鱼
P:在三文鱼产卵季节,大鱼很多
GAP: 熊赶走小鱼 v.s. 大鱼在产卵季节 à 小鱼 v.s. 大鱼
加强方向:
放走小鱼,小鱼长大了之后,熊就有更多大鱼吃

两个组,变量是diet,削弱的话看看有没有他因,或者样本有没有代表性?
选(3)

熊在鱼的产卵器不吃小鱼=> 熊知道吃完之后以后就没得吃了?其他三文鱼产卵也不吃?
狗熊在每年的其他三文鱼产卵的时段也不吃
