看来，最近大家对lsat很感兴趣，我们很快就会在逻辑区开展一个lsat逻辑题的讨论学习活动。

Which one of the following, if true, most strongly supports the position that the traditional attribution of a disputed painting should not have special weight?

题目问，下面那一个可以支持我们不应该过分倚重传统attribution of a disputed painting。

(A) Art dealers have always been led by economic self-interest to attribute any unsigned paintings of merit to recognized masters rather than to obscure artists.

有效的举出一个例子用来指出traditional attribution 的弱点，从而起到支持作用。

那请问GG，这样的算不算他因否定呢，是不是属于无关选项呢？

我觉得应该属于直接支持，不应该算他因否定和无关选项

加为精华贴，便于大家讨论。

我的意见是：

简单讲，我认为fact是不可能做premise。因为premise是an idea that you use to support another theory。that idea can be wrong. but fact is that thing happened indeed in the past, it must be true.

举一个例子：
在热恋中，所有男孩子都要给女孩子送花。
我是男孩子且在热恋
所以，我也要送花（后面的但是我没钱，能否像你借钱somethings like that）

在热恋中，所有男孩子都要给女孩子送花。（大前提）
我是男孩子且在热恋（小前提）
所以，我也要送花（结论）

由此看出，前提是一种理论，我认为正确，从而推出有利于我的或我想要得结论。决不是一个事实。至于“在热恋中，所有男孩子都要给女孩子送花。“是不是事实，(例如，就有女追男的吗！） who knows! who care! that is my premise.

这时你可以说：“我们邻居小张就是送的花，结果去年就结婚了。“

这就是一个事实，用来支持你的论证。
实际上8题并不是一个推论性的论证。他实际上是一个因果关系
先描述了一个现象，然后提出了一个因果论证。
希望对你有所帮助。

今天的问题
SET17 Ⅲ
9. Fines levied against those responsible for certain environmentally damaging accidents are now so high that it costs a company responsible for such an accident more to pay the fine than it would have cost to adopt measures that would have prevented the accident. Therefore, since businesses value their profits, those that might have such accidents will now install adequate environmental safeguards

Which one of the following, if true, most seriously weakens the argument?

(A) Businesses generally greatly underestimate the risk of future accidents.

(B) Businesses are as concerned with long-term as they are with short-term strategies for maximizing profits.

(C) Businesses generally do the environmentally "right" thing only if doing so makes good business sense.

(D) Businesses treat fines that are levied against them as an ordinary business expense.

(E) Businesses are learning to exploit the public's environmental awareness in promoting themselves


答案选A，我觉得A不是正好支持文中的观点吗，因为他们低估risk of future accidents
所以才不愿采取措施啊

D为什么不对啊，我他们正式把罚款看做日常支出，那么才不在乎罚款，不是吗

迷茫

第二题：
我觉得你已将选a的原因讲出来了。因为，原文的观点是：厂家由于怕罚款所以不得不采取预防措施。a said that they do not care certain environmentally damaging accidents in the future. 直接反对作者的论据。Fines are now so high that t would have cost to adopt measures that would have prevented the accident.
D为什么不对啊，我他们正式把罚款看做日常支出，那么才不在乎罚款，不是吗?
这可不一样，这只是其记帐方法的不同而已，也是会影响利润的。不能推出那么才不在乎罚款。

以下是引用joice在2003-9-19 8:24:00的发言：
Say, sea water contains  oxygen-16 and  oxygen-18. During ice age, vapor doesn't return to sea, greater proportion of oxygen-16 lost while ox-18 only  lost smaller proportion, so proportion of Ox-18 in seawater increases.

第三题，完全同意joice的解释！这个题是一个有关比例的题。拿走的和留下的，在总数不变得情况下，是一增一减的关系

18. In the United States proven oil reserves-the amount of oil considered extractable from known fields-are at the same level as they were ten years ago. Yet over this same period no new oil fields of any consequence have been discovered, and the annual consumption of domestically produced oil has increased.

Which one of the following, if true best reconciles the discrepancy described above?

(A) Over the past decade the annual consumption of imported oil has increased more rapidly than that of domestic oil in the United States.

(B) Conservation measures have lowered the rate of growth of domestic oil consumption from what it was a decade ago.

(C) Oil exploration in the United States has slowed due to increased concern over the environmental impact of such exploration.

(D) The price of domestically produced oil has fallen substantially over the past decade.

(E) Due to technological advances over the last decade, much oil previously considered unextractable is now considered extractable.

答案是选E
我觉得A 也没错啊
进口多了
即使开采的少，也能增加数量啊

a的错误属于scope shift.题目的矛盾在于国产油的储量和消耗量。而a却引入了进口油，属于无关选项排出。
