Twelve years ago and again five years ago, there were extended periods when the Darfir Republic's currency, the pundra, was weak:its value was unusually low relative to the world's most stable currencies.Both times a weak pundra made Darfir's manufactured products a bargain on world markets, and Darfir's exports were up substantially.Now some politicians are saying that, in order to cause another similarly sized increase in exports, the government should allow the pundra to become weak again.

Which of the following, if true, provides the government with the strongest grounds to doubt that the politicians' recommendation, if followed, will achieve its aim?

(A) Several of the politicians now recommending that the pundra be allowed to become weak made that same recommendation before each of the last two periods of currency weakness.

(B)[c1] After several decades of operating well below peak capacity, Darfir's manufacturing sector is now operating at near-peak levels.

(C) The economy of a country experiencing a rise in exports will become healthier only if the country's currency is strong or the rise in exports is significant.

(D) Those countries whose manufactured products compete with Darfir's on the world market all currently have stable currencies.

(E) A sharp improvement in the efficiency of Darfir's manufacturing plants would make Darfir's products a bargain on world markets even without any weakening of the pundra relative to other currencies.

[c1]Correct. manufacturing已经到peak level无法再提高生产，没有办法再exports了。有因无果

E选项是逻辑链成立的另外一个原因，之前有人说E不对是因为：“提高生产效率很好，平均价格降低，提高国际市场竞争力，可以出口更多。但同时，并不妨碍货币贬值会带来更多更大的利益和好处。方法1可以提高出口，方法2也可以提高出口，为什么不两种办法都用呢？政府没有理由因为货币贬值可以带来更多的利益而否掉货币贬值。”

所以我就困扰了，那“他因”要怎样才能算对呢？求NN解惑啊~~~~或者给我个链接看看。。。已经昏头了。。。

这不是因果型结论cause-related 应该是类比题。。。fause-analogy
twenties years ago and again five years ago, the currency is weaken, and the exports increased
so again if we want to increase exports today, the currency should be weaken.

得出这个结论→ 即为了要今天的出口增加就必须要今天的货币贬值
如果我们需要削弱就必须说不可比当两种情况不一样时候才不可比

即为B选项这不是它因吧偶觉得。。

E 整个就是无关哒。。。大前提就错了讨论的逻辑链是【贬值--出口】
without 贬值就已经跳出这个逻辑链了

104.Although the discountstores in Goreville’s central shopping district are expected to close withinfive years as a result of competition from a SpendLess discount departmentstore that just opened, those locations will not stay vacant for long. In the five years since the openingof Colson’s, a nondiscount department store, a new store has opened at the

location of every store in theshopping district that closed because it could not compete with Colson’s.

Whichof the following, if true, most seriously weakens the argument?

(A)Many customers of Colson’s are expected to do

lessshopping there than they did before the

SpendLessstore opened.

(B) Increasingly, the stores that have opened in the

central shopping district since Colson’s opened

have been discount stores.

(C)At present, the central shopping district has as

manystores operating in it as it ever had.

(D)Over the course of the next fi ve years, it is

expectedthat Goreville’s population will grow at

Although fullerenes--spherical molecules madeentirely of carbon--were first found in the laboratory, they havesince been found in nature, formed in fissures of the rare mineral shungite. Since laboratory synthesis of fullerenesrequires distinctive conditions of temperature and pressure, this discoveryshould give geologists a test case for evaluating hypotheses about the state ofthe Earth's crust at the time these naturally occurring fullerenes were formed.

Which of the following, if true, most seriouslyundermines the argument?

(A) Confirming that the shungite genuinelycontained fullerenes took careful experimentation.

(B) Some fullerenes have also been found on theremains of a small meteorite that collided with a spacecraft.

(C) The mineral shungite itself contains largeamounts of carbon, from which the fullerenes apparently formed.

(D) The naturally occurring fullerenesare arranged in a previously unknown crystalline structure.

(E) Shungite itself is formed only underdistinctive conditions.

看到原文里有in order to，第一反应就当措施推目的做了。。。晕倒。。

plan-goal也不对感觉错了
plan-goal应该是这种类型
举个例子：currency的weaken有着很多的效果比如宏观调控国家经济抑制通货膨胀增加出口 although currency 的weaken会伴随着经济的小部分衰败但是某国家In order to 增加出口仍然plan to weaken currency。这才是Plan-goal 这个时候B选项也是OK的反驳plan 说明goal达不到

而你说的cause-related也是感觉错的。
cause-related；两个fact发生了：在过去的几年中货币紧缩了且出口增加了结论：是紧缩的货币政策导致了出口增加这个时候B就不行了这个时候才叫他因法比如什么国外的市场发展好啊国内的industry 有效率啊--你选的E选项等等。你之所以纠结E我觉得就是划错了类型吧。。。O(∩_∩)O~

也就是说，只能在cause-related这种型的题目里，才会出现他因作为正确选项，其他类型的应该判为无关？

上邪 · 发表于 2012-5-2 23:51:17

不是吧我觉得。。无关不无关得看逻辑链超出promise-conclusion的才是无关作用于上面的哪怕内容表面上看起来扯得再远只要有作用那也是选项吖呵呵。。
但是这个题这两天我正在横向。。额应该说大部分折中类型的因果型结论都是找她因
比如：志愿者活的长因此志愿活动导致长寿 ---正确答案就是志愿者都是女人女人容易长寿
但是比如什么实验的这种类型的因果型题：老鼠容易死同时发现老鼠吃的S比较多因此是S导致了老鼠死亡这个时候就可以用有因无果切断因果什么的。
他因法单独划给因果型有点绝对了。。
呵呵。。个人看法。。。再探讨啦。。我也怕说错。。
但是上面两个例子应该没问题。。

比如OG那道家具的题应该是OG的吧什么观察家发现30年前的家具质量比现在的好因此过去的工匠的技术比现在工匠的技术好他因法：好房子不容易踏---因此坏房子都塌光了留下来的让你看见的都是质量好的这也是他因法这就不是因果型结论

还比如GWD那道滑雪的题什么几年前小孩子都用木质的滑雪板现在用铁的我们发现现在小孩滑雪受伤的比以前的多结论铁的比较硬铁的容易伤害小孩
答案就是现在小孩用铁质滑板滑的地域比以前大---就是说用铁质的人多了。 GWD的答案比较绕。。木有直接告诉你用铁的人多了。。。呵呵这也是他因法这就不是因果型
