premise:in the long run, many history instances' demonstration
conclusion:if the firm want to retain power, it should act responsibly and an example to support.
bg info: the company will lose power if it act irresponsibly
prephrase:weaken--->it's not the only reason why the company lose power/acting responsibly will also lose power/no causal relationship
这个也是一个conditional conclusion也就是说要满足某一条件，这个结论才能成立
Airrelevent
Birrelevent
Ckept for the first round.irrelevent point--power erode slowly
Dirrelevent
Ekept for the first round.right
OA:B (B) Public relations programs can cause society to consider an institution socially responsible even when it is not.
这个思路是破坏因果关系让irresponsible action也能retain power
E) Some businesses that have used power in socially responsible ways have lost it.
错因1.混淆了want to retain 和already retain 2.attacking Mistaken Reversal of the conclusion
***结论的推理顺序也非常非常重要，题目的顺序：want to retain--->it should act responsibly，但是E是act responsibly--->lose power这样就反了
Mistaken Reversal of the conclusion, and so the attack is made on a statement that uses the same terms as the conclusion but puts them in
a different relationship

P: 从长时间来看那些没有act 社会责任所需要的manner的公司都会失去一些power.
C: 一个公司如果想延长它的power就必须act responsibly.
推测：原题中是延长power-->act responsibly. 要证明act responsibly不是可以让公司延长power的唯一选择；
选项分析：B
A: 无关，不管是政府机构还是business机构都要遵守社会责任
B：提供了另一个不act responsibly的方法
C: 这里说的是保留权利长短的问题，原题所说得是是否保留的问题。
D: 与act无关
E: 这题证明的是act responsible 可能不能延长power，与原题的逻辑链是反的。

B: US 生产了很多太阳能generator，大部分出口到欧洲。但是欧洲的市场是由本地的公司控制的。
P: US政府决定资助这些工厂来鼓励美国人使用US制造的太阳能发电机。
C: 如果这个计划成功，需求量增大，US工厂将可能保持较高的生产水平。
推测：证明即使不去跟欧洲竞争，US内部需求量增加，本地工厂也会竞争。US的生产水平就会提高
选项分析：C
3.32s
B：吸烟的然的lung功能不如不吸烟的人。
P：通过测试每秒呼吸的数量得出，血液中含有某种营养越高，lung的功能越好。
C: 吸烟的人多吃含有这种营养成分的食物是一种有助于肺功能的方法。
推测：证明烟中的某些物质不会影响这些营养；呼出的氧气能完全证明肺功能的好坏。
选项分析：E
4.1min15s
B: 科学家研究一个comet撞到Jupiter之后变成的fragment有多大。
P：发现了只存在于Jupiter大气层下面的硫磺，fragment跑到大气里面才会有硫磺。
C：一些fragment足够大到跑到Jupiter大气层里面。
推测：第一部分陈述了一个事实，这个事实可以用来证明结论；第二部分是结论。
选项分析：E
5.18s
B：铀是从mines中开采出来的。
P：铀也可以从seawater中开采，但是开采的花销大于售价。
C：除非开采的费用降低，否则从seawater中开采这个方法将不会被采用。
推测：是否seawater开采能带来其他收益；是否mines中的量足够
选项分析：A

P: society will reduce power when business is not responsible
C: a business wants to retain power as long as it can must act responsibly
Logic: not A when not B, so want A must do B, 没有责任就没有power，要有power就一定要有责任。Weaken：有责任不一定有power

a)        Government institution is irrelevant
b)        PR is irrelevant business can retain without responsibility, correct
c)        Some, not prefer
d)        Irrelevant
e)        Correct wrong. Some is not preferred, and can’t hurt conclusion

Bg: us encourage use of solar power in US, because EU may capture the EU market in the future
C: US will maintain production level
P? increased US market should equal to lost EU market

a)        Irrelevant
b)        Irrelevant
c)        The production should increase  US production increases while EU’s decreases – maintain high production
d)        Irrelevant
e)        Weaken

P: high level of certain vitamins and minerals in the bloodstream is good to a person’s lung function
C: intake food that rich V and M will improve smokers’ lung function
Assumption: the V and M in food can go into the bloodstream. Smokers lung function is related to the level of V and M

a)        Not mention lung function. Irrelevant
b)        取非：smoker’s lung function is not better than nonsmokers. irrelevant
c)        取非：少吃v和m的人有肺以外的健康问题。Irrelevant
d)        取非：不抽烟会比改善饮食效果更好。更好不代表不能
e)        Correct。 取非：抽烟阻碍v和m的摄入

C: some fragments were large enough to pass J’s outer atmosphere
P: sulfur would seep into outer atmosphere
Logci : 第二句是c, 第一句支持c
选e

P: the cost of extract u from seawater is greater than the price
C: the method is unlikely to be commercially viable

a)        The price of u might increase. Correct
