GWD-9-Q24:  这个C不是假设，原文已经给出了一个信息studies, however, show that cars owned by Greatport residents are, on average, slightly less likely to be involved in a collision than cars in Fairmont. 而这个结论是通过这个study得出来的，所以，不管你是不是more likely to report it ，都没什么关系呀。

本来很困鸟, 看到大家都来了, 回了回数学贴子, 就又不困鸟, 不过得强迫自己睡觉鸟, 不然明天早上起来不鸟鸟~!!

谢谢滴闹闹~明天我再仔细研究你的解释~~加油加油~!!

YAOYAO,今天突破什么啊?

JOJO, 又热心滴来帮偶们鸟~!! 真是运气好啊~~年底交到这么一帮好同伴~~!!

各位, 我做猪去鸟~~

我现在也没突破啥，这两天背作文魔板，做数学题，隔一天做一套题，verbal这两天除了做题也没分析，本来想着把GWD的阅读看一遍，可是好多都没做……也想把sc看一遍，可是prep还没看……逻辑我觉得考试前我把黄金80题和jj看完就差不多了

jojo，我现在很多很多东西都没弄完，可我只能把最能短期内提高一点分数的东西做完了，给我点建议吧？

莉香mm晚安~~~~~~~~

今天重看了GWD1-13的假设部分, 又发现一些不太清楚的地方, 拿出来大家讨论讨论~~闹闹^-^可能就是你正看看的呢, 我现在都还米有搞清楚~~汗~~希望我不会再将这里弄成逻辑的海洋~~

GWD-6-Q4:

In the past the country of Siduria has relied heavily on imported oil.  Siduria recently implemented a program to convert heating systems from oil to natural gas.  Siduria already produces more natural gas each year than it burns, and oil production in Sidurian oil fields is increasing at a steady pace.  If these trends in fuel production and usage continue, therefore, Sidurian reliance on foreign sources for fuel should decline soon.

 

 

Which of the following is an assumption on which the argument depends?

 

 

1. In Siduria the rate of fuel consumption is rising no more quickly than the rate of fuel production.

2. Domestic production of natural gas is rising faster than is domestic production of oil in Siduria.

3. No fuel other than natural gas is expected to be used as a replacement for oil in Siduria.

4. Buildings cannot be heated by solar energy rather than by oil or natural gas.

5. All new homes that are being built will have natural-gas-burning heating systems.

 

 

这一题, 我十分赞同选(A), 但是有个疑问, 题目说Siduria already produces more natural gas each year than it burns, and oil production in Sidurian oil fields is increasing at a steady pace.  If these trends in fuel production and usage continue, 我记得lawyer说, 带有IF 结论的题目中, IF条件是前提, 怎么感觉(A)与题目前提重复了呢? 好像就是把题目中的前提复述了一遍, 也算是假设吗?

 偶不认为这是重复题目前提。来看看，题目说的是:already produce（一直以来都是这样）, A选项用的是is rising（将来会这样）。更准确来说题目说的是过去＋现在，而只有加上了A说的将来，这个assumption才完整了。

GWD-9-Q40:

Agricultural societies cannot exist without staple crops. Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental, not staple, foods. All the recorded staple crops grown in western Africa were introduced from elsewhere, beginning, at some unknown date, with rice and yams. Therefore, discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there.

 

 

Which of the following is an assumption on which the argument depends?

 

 

A. People in western Africa did not develop staple crops that they stopped cultivating once rice and yams were introduced.

B. There are no plants native to western Africa that, if domesticated, could serve as staple food crops. 没有涉及关键问题：时间

C. Rice and yams were grown as staple crops by the earliest agricultural societies outside of western Africa.

D. Kola and okra are better suited to growing conditions in western Africa than domesticated rice and yams are.

E. Kola and okra were domesticated in western Africa before rice and yams were introduced there.

Answer:A

 

 

我同意答案(A), 但是我又觉得这是一个重复前提的选项. 前提是无主要作物就无农业社会，论据是在米和番薯引入西非之前，西非没有主要作物，结论是西非的农业社会是从米和番薯的引入开始的（文章中是时间）。其假设是在米和番薯之前，西非没有主要作物。a说明，此前确实没有。

题目已经告诉你了没有主要作物了, 怎么还假设呢?

 这个题目其实比较诈，就诈在丽香MM hightlight红色的recorded上了。A其实也不尽完美，它应该说明这些中途退出历史舞台的作物是米有历史记载的。

这两个题目的答案我都非常同意~~但是不明白的是, 为什么对题目条件的重复也可以做假设呢?

MM，偶常常觉得你对逻辑的理解已经很好了耶，哈~~^_^开心~

GWD-5-3：

结论：Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.

The number of televisions assembled annually in Vernland has not increased significantly during the past three years.

晕了，你还真这么想啊？我从来不用取非的方法做假设题的，因为总是取不准。这个C你取非一下，是不是上面这句？就算增长的不significantly，也不影响B去V那里继续进口吧？

GWD-9-Q24:

For similar cars and drivers, automobile insurance for collision damage has always cost more in Greatport than in Fairmont. Police studies, however, show that cars owned by Greatport residents are, on average, slightly less likely to be involved in a collision than cars in Fairmont. Clearly, therefore, insurance companies are making a greater profit on collision-damage insurance in Greatport than in Fairmont.

G的汽车保险费比F高

G的撞车比F少

----G的保险公司利润比F高。

Which of the following is an assumption on which the argument depends?

 

 

A. Repairing typical collision damage does not cost more in Greatport than in Fairmont.

B. There are no more motorists in Greatport than in Fairmont.

C. Greatport residents who have been in a collision are more likely to report it to their insurance company than Fairmont residents are.还是赚得多。

D. Fairmont and Greatport are the cities with the highest collision-damage insurance rates.

E. The insurance companies were already aware of the difference in the likelihood of collisions before the publication of the police reports.[A]

 

 

虽然Greatport的保险公司的收费高，并且Greatport的车辆事故发生率低，但是如果该地保险公司支付的赔偿金高，其利润不一定高。所以就需要找个选项说明其赔偿金高就可以了, (A) 我同意, 但是我觉得(C) 也可以说明为什么赔偿金高, 因为索要赔偿的人数多啊?
     

也来说说偶滴意见。这题涉及到profit margin的问题，所以必须考虑到的是revenue和cost的比例。原文只告诉你revenue孰高孰低，必须得补出cost是关系才能比较，显然只有A是必须的。

偶觉得C好像有点weaken呐，因为保险费是一定的，你坏不坏车都得付，越多人来报保险我就得支付越多的赔偿啊，如果G修车的成本还挺高的，那岂不是亏大鸟？！

哈,哈, 在最终睡觉之前受到表扬鸟~~~^-^开心~!!跟大家越讨论越开心~~!!越不困~~我的时间恨不得调成中国时间啦~

JOJO的解释真清楚, 不用动脑筋就明白鸟, 想想上星期做GWD也是踏着MM的足迹前进滴~~!!

那么上面那个题目的A选项改为: 在米和番薯引入西非之前,西非并没有"没有记录"的主要作物.就完美鸟~!!

28. GWD-18-Q20

Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development.  They plan to do this by purchasing that land from the farmers who own it.  That plan is ill-conceived:  if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders.  On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable.  But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires.  And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability.

 In the argument as a whole, the two boldface proportions play which of the following roles?

 In the argument as a whole, the two boldface proportions play which of the following roles?

1. The first presents a goal that the argument rejects as ill-conceived; the second is evidence that is presented as grounds for that rejection.

2. The first presents a goal that the argument concludes cannot be attained; the second is a reason offered in support of that conclusion.

3. The first presents a goal that the argument concludes can be attained; the second is a judgment disputing that conclusion.

4. The first presents a goal, strategies for achieving which are being evaluated in the argument; the second is a judgment providing a basis for the argument’s advocacy of a particular strategy.

5. The first presents a goal that the argument endorses; the second presents a situation that the argument contends must be changed if that goal is to be met in the foreseeable future.

(B)项为什么不可以呢?

 亲爱的，B错在concludes cannot be attained啊，谁说这个goal不能实现啦，只不过是用They plan to do this 。。。那种方法实现不鸟而已啊！

我好像是对保险公司的费用这部分没有理解清楚, 保险公司的费用cost是客户claim后支付的赔偿额, 修车的钱是客户自己出(还是保险公司出啊?), G有10次撞车, F有15次撞车, 但是G地有10个人去保险公司索赔, F地只有5个人去索赔, 就算G地的保险费高, 利润也不高啊?
