1. 狒狒logic 倒数第一题
In a new police program, automobile owners in some neighborhoods whose cars are not normally driven between 1 A.M. and 5 A.M. can display a special decal in the cars’ windows and authorize police to stop the cars during those hours to check the drivers’ licenses. The theft rate for cars bearing such decals is much lower than had been usual for cars in those neighborhoods.
If it is concluded from the statements above that automobile theft has been reduced by the program, which one of the following would be most important to answer in evaluating that conclusion?

A: Are owners who are cautious enough to join the program taking other special measures to protect their cars against theft?

2. 狒狒logic 倒数第二题
The more television children watch, the less competent they are in mathematical knowledge. More than a third of children in the United States watch television for more than five hours a day; in South Korea the figure is only 7 percent. But whereas less than 15 percent of children in the United States understand advanced measurement and geometric concepts, 40 percent of South Korean children are competent in these areas. Therefore, if United States children are to do well in mathematics, they must watch less television.
Which one of the following is an assumption upon in advanced measurement and geometric concepts than are South Korean children?

A: The instruction in advanced measurement and geometric concepts available to children in the United States is not substantially worse than that available to South Korean children.
3. 狒狒logic 倒数第三题
Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmosphere carbon causes decreased evaporation from the oceans, which cause less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax---nature will continually adjust the carbon level.
Which one of the following, if true, would most weaken the argument in the passage?
A: The natural adjustment process, which occurs over millions of years, allow wide fluctuations in the carbon level in the short term
说实话，我现在觉得这个答案不是很好。不过在原题里，这个答案应该算是最相关的。它的着眼点是"over past millions of years"，以此说明“那个时候没有人存在”，从而说明人类这么干会有影响。但是，我能想到的方法还是去说明"Nature cannot withstand such fluctuation."
4. 逻辑大全6-19
In January there was a large drop in the number of new houses sold, because interest rates for mortgages were falling and many consumers were waiting to see how low the rates would go. This large sales drop was accompanied by a sharp rise in the average price of new houses sold.
Which of the following, if true, best explains the sharp rise in the average price of new houses?
A: Sales of higher-priced houses were unaffected by the sales drop because their purchasers have fewer constraints limiting the total amount they pay.

5. 这貌似是4个月前被我定义为“精选的恶心AWA中的一篇”= =，我们来受下虐。。
(18)The following is an excerpt from a memo written by the head of a governmental department.
“Neither stronger ethics regulations nor stronger enforcement mechanisms are necessary to ensure ethical behavior by companies doing business with this department. We already have a code of ethics that companies have agreed to follow it. We also know that the code is relevant to the current business environment because it was approved within the last year, and in direct response to specific violations committed by companies with which we were then working- not in abstract anticipation of potential violations, as so many such codes are.”

Premise: Korean children watch less TV and they are smarter.
Conclusion: US children should watch less TV in order to be more competent.
Assumption: 问题没读懂，是不是说美国和南韩孩子之间的advanced study的比较?如果是，我觉得是不是说书本的material是一样的之类的，这样才能用取非方法来weaken conclusion

50s
Premise: The carbon level is affected by nature
Conclusion: So the scientists don't have to worry if the carbon level will cause human life in danger.
Weaken: The nature would produce special particles when the air meets enough fuel and finally increase the carbon level.

bat: 关于evaluation的题目，如果我没有题目就想不出来要怎么表达，虽然我知道evaluation主要是weaken conclusion的，但是怎样用更贴近答案的形式在看选项前在脑中有一个大概的印象？我只能用链接谁引导谁来推出答案。你是怎么做的？

AWA:
Premise: We have approved a code to enforce the ethic of a company.
Conclusion: New enforcement and regulation can't ensure the ethic of a company at the end.
Reasoning:
The approved code of ethic regulation can't apply to all companies in all situations since each company has its own character.
It's hard to monitor if all companies follow the code in all situations even though they agree to follow it.
It's better to have a supplementary code upon this approved code when each company deals with different depts.

这样理解对不对啊？我怎么觉得我在做weaken CR~

半夜不睡觉搞逻辑，难道语言都表达不清了？还是到这边来太久了，english没学会chinese也忘了？
我是说evaluation的题目好像都是可以用否定或是肯定的答题方式来看是否可以strengthen/weaken 原题来做的。
哎哎啊，简单点吧：你是怎么想到“any other methods"的？和答案这么吻合?就是你做这类题没看答案以前脑子是怎样出现这个答案的？

来对答案~~：
1.
看漏了题目的结论: Automobile theft has been reduced by the program

2.
50. Although computers can enhance people’s ability to communicate, computer games are a cause of underdeveloped communication skills in children. After-school hours spent playing computer games are hours not spent talking with people. Therefore, children who spend all their spare time playing these games have less experience in interpersonal communication than other children have.
The argument depends on which of the following assumptions?
(C) Children who do not spend all of their after-school hours playing computer games spend at least some of that time talking with other people.
第二题觉得和OG这题很像，就用了这题的思路。
但答案不一样。因为OG里强调的是After-school hours spent playing computer games are hours not spent talking with people. 狒狒这题没有强调这点。
只要排除other factors就是assumption。

3.
狒狒逻辑解释：
In my view, the reasoning in this argument is that:
nature will continually adjust the carbon level a sustained increase in the level of carbon would not threaten human life.
The statement of E points out that even the nature will continually adjust the carbon level, wide fluctuations in the carbon level in the short term will exert the remarkable negative to the human life.(Common sense tells us that the life of human is often less than 100 years)
So, E is the correct chose.
貌似这里的point不是nature能不能continually adjust the carbon level，而是人类能不能承受这个level。

4.
Sales of higher-priced houses were unaffected by the sales drop because their purchasers have fewer constraints limiting the total amount they pay.
就是说那些购买者不介意价钱？？

啊啊！我才看到。。。画圈认错.....
好像这种题型应该是一类吧~不确定，很久没看了。题型如下：
给出一个fact，由这个fact得出一个结论，这个结论是用来解释这个fact。（最后这句很重要！）
削弱方法：1. 一般都是有它因（就是不可能是去攻击premise，从而来weaken conclusion, 原因我自认为是“fact无法被攻击”【此处的fact还不同于research，research, observtation可以被攻击，而fact有效性是不能被攻击的额。。】）
2. 给出有因无果的例子（这个GWD里老见。。GWD的恶心地方就在于，好多题不是去攻击premise,而是举例子！而那堆例子还都是【有因无果】的具体化例子，得仔细读明白了，还得能有反应。。）

加强方法：1. 排除它因出现的可能 2. 强化有因有果，无因无果（一般也是例子）

evaluation：那就是上面二者结合了~~~~~

第三题，同意diasy~原来我一直看错了关注点。。。那既然它的concern应该是人类能不能sustain，恩。。那就应该是如daisy所说~

第四题，大意就是他们不关注钱。其实可以这么理解：“好多人不买房，是因为他们想看贷款利率能降到什么程度”，“但是，房价却升了”
原因在于“那些买的起高价房的人仍在买房（因为他们是现款买房）- -”

Condition 2若含碳量减少，则蒸发减少。
环境学家担心矿物燃料燃烧会过度增加大气含碳量，威胁人类。
Argument: No worries啦，反正大自然会调节的。

Weaken: 当含碳量增加到一定程度时，大自然的调节就会失灵的。

4. BG: 一月新房子的销售量下降。
Reason: 因为抵押利率降低，人们还在观望，看会降低到什么程度。
BG2：销售量下降伴随新房平均房价急剧增长。
Explanation:
先发了免得又没了==+

接上：
为啥房价会上涨捏？
供求关系好像解释不通，那我猜。。猜不出来看答案吧。。。==+
答案的意思是？高价的那部分房子销售量木有收到利率的影响，因为那些潜在购买者都是有钱淫，他们本来就无所谓利率多高滴。

1. 58’s

P: if the car has a decal, police can stop it between 1am to 5 am.

P: theft rate is lower for these cars than other cars

C: theft rate in total has been reduced by the program

【因果】有了D，D车偷盗率少了。所以整体偷盗率降低。

整体是否降低，和D在整体中所占比例有关系。如果D比例很大，整体降低合情合理。如果比例小，那么有他因。

评价，削弱方向，看他因。

P: if more television, then less mathematical competence.
P: more than one third of American watch more than 5 hours tv, while only7 percent of the Korean watch.
P: less than 15 percent of American understand geo, while 40 percent of Korean.
C: to improve US math competence, must watch less tv.
【因果】1/3美国人看电视，韩国7%，结果15%美国人熟悉几何，韩国40%。在看电视和数学能力建立因果关系。
有几个gap: 1) 分数不等于number, 美国人看电视的人数不一定多余韩国的。这里假设美国人数更多。2）advanced measurement, geo concepts=mathematical knowledge. 桥梁。3）排他，数学能力只和看电视有关，和其他无关。

3. 1’09
P：natural could adjust carbon level by the circle: carbon—heat—water evaporated—rain—human life
P: increased level of carbon will damage human life
C: not worried, the nature will adjust itself
【逻辑链】环境学家以为增加的carbon会损害人类。但是结论认为，自然自己会调解carbon level，所以不用担心。
削弱：方向就是自然不能调解。如果carbon level超出了自然调解的范围，就不能调解了。或者指出自然可以调解的前提。

4. 27’

P: sales of house drop---interest rate for mortgage reduced—average price of house increased

【差异】销量下降，贷款利率下降，价钱上升。

5.

P: we have a code of ethics

P: the code is relevant to current business environment that was approved last year, and in direct response to violations of companies we were working

C: we do not need ethics regulations and enforcement mechanisms to ensure ethical behavior

1. 错误假设：wrongly assume that the relevant code of ethics we currently have is sufficient to ensure ethical behavior

2. 错误假设：assume that the code that was approved last year is still relevant to current business environment, assume that the business environment did not change within the year

3. 例子代表性：assume the violations by companies we were working are representative of all the possible violations of current companies we are working. Assume that there are no additional or new violations under the current business environment

1. 狒狒logic 倒数第一题
In a new police program, automobile owners in some neighborhoods whose cars are not normally driven between 1 A.M. and 5 A.M. can display a special decal in the cars’ windows and authorize police to stop the cars during those hours to check the drivers’ licenses. The theft rate for cars bearing such decals is much lower than had been usual for cars in those neighborhoods.
If it is concluded from the statements above that automobile theft has been reduced by the program, which one of the following would be most important to answer in evaluating that conclusion?

A: Are
67’
p：不在早上1点到5点用automobile的人车上会有一个标记，那么如果在那个时间段出来了警察会查驾驶证
C：有了这项规定以后thief少了很多
Key：是由于这项规定减少的（而不是还有别的原因）or是在1~5am发现的thief减少special measures to protect their cars against theft?

2. 狒狒logic 倒数第二题
The more television children watch, the less competent they are in mathematical knowledge. More than a third of children in the United States watch television for more than five hours a day; in South Korea the figure is only 7 percent. But whereas less than 15 percent of children in the United States understand advanced measurement and geometric concepts, 40 percent of South Korean children are competent in these areas. Therefore, if United States children are to do well in mathematics, they must watch less television.
Which one of the following is an assumption upon in advanced measurement and geometric concepts than are South Korean children?

39’
P：看电视越多数学越差
P：33%的美国孩子每天看电视超过5个小时，在韩国7%
P：15%的美国孩子掌握一定的math技巧，40%的韩国孩子也有同样的技巧
C：如果美国孩子超过韩国孩子，那么一定看电视看的少
Key：排除会使数学技能差的他因eometric concepts available to children in the United States is not substantially worse than that available to South Korean children.
3. 狒狒logic 倒数第三题
Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmosphere carbon causes decreased evaporation from the oceans, which cause less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax---nature will continually adjust the carbon level.
Which one of the following, if true, would most weaken the argument in the passage?
61’
P：自然会不断的调整大气中C的含量
P：C+→大气更能保温→更多水蒸发→更多雨→更多C从空气到海→形成seabed（反之亦然）
P：有人担心燃烧fossil fuel会使得C+到达一个危险的高度→危害生命
C：不用担心，因为自然会不断调整C的含量 short term
说实话，我现在觉得这个答案不是很好。不过在原题里，这个答案应该算是最相关的。它的着眼点是"over past millions of years"，以此说明“那个时候没有人存在”，从而说明人类这么干会有影响。但是，我能想到的方法还是去说明"Nature cannot withstand such fluctuation."
4. 逻辑大全6-19
In January there was a large drop in the number of new houses sold, because interest rates for mortgages were falling and many consumers were waiting to see how low the rates would go. This large sales drop was accompanied by a sharp rise in the average price of new houses sold.
Which of the following, if true, best explains the sharp rise in the average price of new houses?
A:
P：按揭的贷款I→房子sold的数量-（因为人们想看看贷款利率可以降到什么程度）
P：但是新房每套房子的卖价+，why？le
