To joywzy:

T2
C tell us that there are some limit before we can use gasoline instead of wood economically...so C support the conclusion... I agree that C use such words as "narrow",which seems not good enough to support the conclusion...However, the "relatively" used to modify "narrow" compensate for this weakness..

T7.
we should know the connection of the cause and effect in this question... The arguer tell us that because the advertisement in only 3 months has attacted enough contributors, an advertisment in more than 3 months will certainly attract more contributors...you can see between the cause and effect, there is a gap or prediction...Even if most of those contributor contribute to the advertisement in response to the advertisement, as D said, it just repeat the cause of the argument(advertisement attracts 70 percent of its contributors)...we still can  not make sure that the propose of arguer will take effect unless we add some premise such as choice A...

T10
A is a irrelevant choice...
You should notice the first sentence:
more persons diagnosed as having the ....were born in the winter months than at any other time of year...
This is a phenomenon, the arguer give an explanation...
A is irrelavant because it only talk about how the illness occurs, but does not talk about the reason why the illness were most related to the winter months, a reason the arguer want to explain...So  A will be a good choice if A is  changed to: the reason why most persons diagonsed as ....were born in th winter months is NOT because other factor, such as....

T39
there are two reasons for the reduction  of contamination..
1.  law took effect in 1975
2. the drop in the use of gasoline between 1975-1985

if the law does contribute most to the decline, most of the contamination decline will occur after 1975, the year that law took effect....B tell us that most the use of gasoline decline happened between 1980 and 1985, we have no reason to believe that it is an effect of 1975-LAW, we would rather believe other reasons contribute to the decline... So the key to solve such question is the date...notice the difference of the date and try to use the difference of the year to solve the problem

A the contamination fell sharply in both 1975 and 1983... choice tell us that both the law and the drop in the use of gasoline contribute to the contamination...

今天做了LSAT18，还是错很多，两道题请教一下各位：
SEC-IV
5. The city is vigorously enforcing the ordinance against allowing individuals to sleep in the bus depot. The mayor argues that such vigorous enforcement is fair, evenhanded, and administered in the best traditions of equal treatment for all "No one can sleep in the bus depot," the mayor has said, "whether you're homeless or the chief executive of a major corporation." This brings to mind a remark once made by a political commentator. The law in its majestic equality, forbids the rich as well as the poor to sleep under bridges, to beg in the streets, and to steal bread, it's time for the mayor to come to his senses.

The passage as a whole is structured to lead which one of the following conclusions?

(A) People should not be treated equally with respect to enforcing the ordinance vigorously.

(B) Everyone should be treated equally with respect to enforcing the ordinance vigorously.

(C) The vigorous enforcement of the ordinance does not qualify as equal treatment for all

(D) The law holds poor people to stricter standards than it does rich people.

(E) In a truly equal legal system, no one would sleep in bus depots.
答案是C，我选B，为什么说这个法律不是对每个人都平等？引用的例子说的也是平等吧？

22. George: The economics taught in college is very confusing-and that's because it's all wrong. Harold: If it's all wrong, why is college economics still force-fed to students? George: It's very difficult to learn something that's all wrong, and if, by chance, someone does waste all that time and learn it, he or she will be inclined to defend it ferociously and pass it on to others.

Which one of the following, if true, would most directly challenge George's reasoning?

(A) Many college graduates who have taken economics go on to successful careers in a variety of other fields.

(B) College students who major in economics tend to earn higher grades in economics than in their other subjects.

(C) "Right" and "wrong" are relative terms in the field of economics.

(D) Many economics professors agree with journal articles that strongly criticize college economics.

(E) Interviews five years after graduation show that economics majors are just as likely to say that their college experience was enjoyable as are those who did not major in economics.
答案是D，我选A。D是支持George而不是反驳吧？

1. the argument tell us :
becasue the rich are different from the poor, who have less power and resource to solve their daily trouble, a vigorous enforcement of seemly equal law is actually an equal to the poor...

2. the line of reasoning is that if something is not useful, someone who took time to learn it will not pass it to others....
D tell us that a lot of professor who do believe that economic course is wrong still pass the economic knowledge to their students...D use a counter example to weaken the argument...

A is not weaken because from A,we can not know that it is the economic course that make the students succeed in their career...maybe other factor contribute to their success and they just take the economic course by chance...

谢谢ALBERT，第2题我懂了，但第1题你说的富人和穷人的区别在文中并未提到呀，不是说不做逻辑不能以通常的思维来考虑问题吗？还是说这是个基本常识，可以不受限制？

再请教一题：
LSAT14 SEC-II
25. Unless negotiations begin soon, the cease-fire will be violated by one of the two sides to the dispute. Negotiations will be held only if other countries have pressured the two sides to negotiate; an agreement will emerge only if other countries continue such pressure throughout the negotiations. But no negotiations will be held until international troops enforcing the cease-fire have demonstrated their ability to counter any aggression from either side, thus suppressing a major incentive for the two sides to resume fighting.

If the statements above are true, and if negotiations between the two sides do begin soon, at the time those negotiations begin each of the following must also be true EXCEPT:

(A) The cease-fire has not been violated by either of the two sides

(B) International troops enforcing the cease-fire have demonstrated that they can counter aggression from either of the two sides

(C) A major incentive for the two sides to resume hostilities has been suppressed

(D) Other countries have exerted pressure on the two sides to the dispute

(E) The negotiations'reaching an agreement depends in part on the actions of other countries.

答案A，我选B。从第一句话就能不能判断A正确，是否要考虑充分必要条件？但B我觉得并不一定会存在。谢了！
