19. GWD-23-Q32
                    

Excavations of the Roman city of Sepphoris have uncovered numerous detailed mosaics depicting several readily identifiable animal species:  a hare, a partridge, and various Mediterranean fish.  Oddly, most of the species represented did not live in the Sepphoris region when these mosaics were created.  Since identical motifs appear in mosaics found in other Roman cities, however, the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.

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

A.      The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area.  (无关)
                    

B.       There is no single region to which all the species depicted in the Sepphoris mosaics are native.
                无关
                    

C.       No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.
                    

D.      All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.
                无关
                    

E.       There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.

请问该如果对C、E 取非？

请问该如果对C、E 取非？

C 是取非no, 还是 do not

C 是取非no, 还是 do not

E 不是很明白意思，，请教，谢谢！！！

E 不是很明白意思，，请教，谢谢！！！

C别急着取非，双重否定就把两个not都去掉看意思，你就会发现C其实是原文的重述

E是说，不同地区的艺术家都很熟悉并且可以共用的mosaic设计取材资源，是不存在的

取非后，就削弱了题目

因为这样一个资源库存在的话，本地的艺术家也有可能(根据这个资源)造出内容是其他地方动物的mosaic了

排除他因的题

建议先翻翻老帖子~

christinawu

明白了，太感谢了，原来E这么个意思。

逻辑专区GWD TN讨论贴不是很全，我已经看过了没有，也不知道该怎么search,发了贴又没人回，不得已才往JJ区发，没想到这么快回复

有个小问题：C.       No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.  这个that 对我干搅很大，以至于没看出来是双重否定。 它是修饰mosaics的吗？    省略掉之后一看很明显是双重否定。

谢谢MM

wangyi217

我觉得是修饰motifs,就和下面这句一个意思

 identical motifs appear in mosaics found in other Roman cities,

说实话，考试的话这种句子确实很难分析......

全靠排除了~

christinawu

哦，知道了，可是下面这题五个选项我全给排除了，答案是A，可我觉得同样起不到削弱作用，我找不到讨论贴，发到群里也没人回答，郁闷呢（还有好几题）~~，麻烦你

TN-17

？41.: GWD-23-Q39

In Gandania, where the government has a monopoly on tobacco sales, the incidence of smoking-related health problems has risen steadily for the last twenty years. The health secretary recently proposed a series of laws aimed at curtailing tobacco use in Gandania. Profits from tobacco sales, however, account for ten percent of Gandania’s annual revenues. Therefore, Gandania cannot afford to institute the proposed laws.

 

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

A.      All health care in Gandania is government-funded.

B.       Implementing the proposed laws is not likely to cause a significant increase in the amount of tobacco Gandania exports.
        ànot likely to increase the annual revenues ( strengthen)
        

C.      The percentage of revenue Gandania receives from tobacco sales has remained steady in recent years.
            ( out of scope)

D.      Profits from tobacco sales far surpass any other single source of revenue for the Gandanian government.    (strenghthen)

E.       No government official in Gandania has ever previously proposed laws aimed at curtailing tobacco use.
            ( out of scope)

G销售烟草带来了健康问题；有人提出法律减少销售烟草；但是结论说因为经济问题，负担不起这个法案

A，健康保健的费用都是政府出的。

就是针对经济问题这个原因来攻击：如果不实施法律限制销售烟草（隐含：让人们的健康问题持续下去），其实还是要政府拿钱的。

这题算是一种套路，就是不做什么，照样有结论中的结果

别死记啊...个人体会

christinawu

明白了，恍然大悟：就是不做什么，照样有结论中的结果

即是套路，我得留心是否还有这种题型，  谢谢MM解惑,非常开心 

就是说 A.      All health care in Gandania is government-funded. 所有的健康保险费用都是政府出的--> 如果不实施法律限制销售烟草（隐含：让人们的健康问题持续下去），其实还是要政府拿钱Pay 这部分的健康保险。如果实施法律限制销售烟草（人们的健康问题好转），虽然由此可能会降低政府收入，但这部分降低的收入可以被减少的health care claim抵消~~ .

再弱问一下，这属于Laywer 解题中的举反例吗?：

条件型结论：结论带条件（即为充分必要）。WEAKEN的方法显示充分条件成立，必要条件可以不成立。或举反例，或提供有关信息。

wangyi217

应该算吧，还有种反例就是最常见的，支持结论后反而出现相反的负面效果

其实这种实行措施啦颁布法令之类的题目，最重要的就是看它的目的是什么

达不到就削弱了，反不反例考试的时候根本没时间想啊^.^

有了收入才有钱支持健康问题

没钱就不能支持。好像在GWD里有很多这样的题。。

christinawu

嗯，知道，读懂题最关键，非常感谢！！！

想归类，这样可以知道每种题型的解题思路，考试时就不会慌张了。
