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

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。

21. The energy an animal must expend to move uphill is proportional to its body weight, whereas the animal's energy output available to perform this task is proportional to its surface area. This is the reason that small animals, like squirrel, can run up a tree trunk almost as fast as they can move on level ground, whereas large animals tend to slow down when they are moving uphill

Which one of the following is an assumption on which the explanation above depends?

(A) The amount of energy needed to move uphill is no greater for large animals that it is for small animals.

(B) Small animals can move more rapidly than large animals can.

(C) The ratio of surface area to body weight is smaller in large animals than it is in small animals.

(D) There is little variation in the ratio of energy output to body weight among animals.

(E) The amount of energy needed to run at a given speed is proportional to the surface area of the running animal.

这题我选A
C想不通

第五题：
又是一道lsat典型的数字比例题！两个因素都对某一事物其作用，且作用是相反的。此时就要看，谁占的比例大，谁的作用就达。
(C) The ratio of surface area to body weight is smaller in large animals than it is in small animals.
他就是这样的选项，一眼就应看出。

set 17,part two

8. The Buysville Chamber of Commerce recently met to discuss a proposal to beautify the Baysville area's treeways by relocating power lines, adding landscaping and removing billboards. At the meeting Mary Simms who was a representing an outdoor advertising company declared "Billboards are the basis of our business. If they are torn down, our ability to earn a living will be severely damaged" , "I don't agree" said Jack Jordan, a local merchant, "The basis of our business is an attractive community, People who might shop in Baysville don't want to see ugly billboards on their way into town. Billboards are hurting our ability to earn a living."

Jack Jordan a remarks suggest that he is misinterpreting which one of the following words used by Mary Simms?

(A) billboards

(B) basis

(C) our

(D) ability

(E) damaged


为什么是OUR啊

第六题：

完全同意joice的意见：

'our business' said by two different group of people, our door advertiser and a local merchant. they are not in the same one group " our'. when the advertiser say ' our business' he mean ' advertise company's business'. but the merchant regard ' our business' as  ' merchant company's business'

set 16 two

  9. Over the past twenty-five years the introduction of labor- saving technologies has greatly reduced the average amount of time a worker needs to produce a given output, potentially both reducing the number of hours each worker works each week and increasing workers' leisure time correspondingly. The average amount of leisure time per worker, however, has increased at only half the rate at which the average hourly output per worker has grown.

If the statements above are true, which one of the following is most strongly supported by them?

(A) Workers on average spend more money on leisure activities today than they did twenty-five years ago.

(B) Labor-saving technologies have created fewer jobs than they have eliminated.

(C) The percentage of the population that is in the work force has grown over the past twenty-five years.

(D) The average hourly output per worker has not risen as much as had been anticipated when modem labor-saving technologies were first introduced.

(E) Twenty-five years ago the average weekly output per worker was less than it is today.

为什么选E
我觉得C对啊，人多了，每个人的相对的休闲时间不就少了吗

第七题：
首先c不对，说就业率提高了，纯属跑题。
e: 是这样得出的：
现在由于技术水平提高，原来用一周时间生产的产量，现在用3天（架设）就够了。 reduced the average amount of time a worker needs to produce a given output。这样，工人就可以多玩三天。但现在，工人只能多玩一天半。has increased at only half the rate at which the average hourly output per worker has grown。这杨剩下的一天半有得干活，这样生产自然多了。
所以：(E) Twenty-five years ago the average weekly output per worker was less than it is today.
