23.土地分配
V1一个国家都是进口麦和马铃薯当做人民的主食.但是如果用这个国家的空地来拿来种这两样食物可以养活全国的人口还有20% more. 所以如果这国家把剩下的土地都拿来种这两种作物,人口增加20%之前都不用.......  答案  当人口增加20%的时候这国家需要拿这些地for more house.

考古：
V1 现状是某国进口tomato和corn两种蔬菜。可是如果该国闲置的可用耕地全部用来种这两种蔬菜的话，即使全国的需求量增加20%也能自给自足；因此即使全国人口增加20%，该国闲置的可用耕地全部利用起来也能满足需求。问削弱 如果人口增加20%，很可能需要利用部分闲置的耕地建造住房

V2（740提供）说一个地方进口谷类和什么东西，但是那个国家有一大块空地，如果用来种那些东西，可以在满足需求的基础上，超额20％。所以假设是，即使人口涨了20％也不影响它的供给能力。问什么是削弱的？我选那个说20％的人口会占用那块土地的一部分用来居住。

24.蚊子和下雨  无法确认答案，两个方面  1.某种原因蚊子没增加2措施控制了传染
V1有一种蚊子会咬人，传播一种病，然后因为蚊子喜欢在水多的地方产卵，今年美国春季的雨水特别多，但是的这种病的人的数量和往年是一样的，问：怎么解释这个现象
因为这种蚊子只在没有下很多雨的的地方产卵”——坐在考场上想的是因为这种蚊子产卵的地方雨水不多，所以它们产的卵数量也就和往年差不多，所以传播的人也不多.

考古：  
V2在美国，有一种蚊子可以传播疾病，而往往在下雨很多的地方这种蚊子就特别多，然而在某个地方，尽管下了很多春雨，但很少有人得那种病，问解释 我选的是这种蚊子在这个下雨的地方很少，

22.葡萄病
一个地方种葡萄的农夫, 大部分都是从某个地方用cut的方法移植过来种的, 近年来发现种这农作物的病是专门靠cut这种媒介传播的, 这种病轻微的症状是会产量很少,但是这跟一般普通低产量的分别很难区别.这地区过去五年都产量很低,所以都是因为这个病的关系,问assumption  
答案,   1.过去五年这种病都没有severely症状的出现
2.这种病不是从去年才开始传播的。

21.花粉传播
V1有一种花有两类，一种是需要像蜜蜂一样的昆虫来帮助开花从而受精，另一种是可以自己来。所以说如果那种需要帮助才能受精的种类如果没有得到昆虫的帮助的话就不能受精

V2问support  预计选项说   依靠昆虫的出问题了，但是self-pollinated没事。

考古：
有些花是通过pollinator传播花粉繁殖，有些是self-pollinated。好像说，通过昆虫传播花粉的species数量大大减少，推论是因为pollinator infection, 问evaluate。（whether the number of self-pollinated species also decreased;….）

20.新设备除有害物质
T-3-Q29.
The emission of sulfur dioxide when high-sulfur coal is burned is restricted by law. New coal-burning plants usually comply with the law by installing expensive equipment to filter sulfur dioxide from their emissions. These new plants could save money by installing instead less expensive cleaning equipment that chemically removes most sulfur from coal before combustion.
Which of the following, if known, would be most relevant to evaluating the claim above about how new-coal burning plants could save money?
A.        Whether existing oil-burning plants are required to filter sulfur dioxide from their emissions.
B.        Whether the expense of installing the cleaning equipment in a new plant is less than the expense of installing the cleaning equipment in an older plant.
C.        Whether the process of cleaning the coal is more expensive than the process of filtering the emissions
D.        Whether lawful emissions of sulfur dioxide form coal-burning plants are damaging the environment.
E.        Whether existing plants that use the filtering equipment could replace this equipment with the cleaning equipment and still complete with new plants that install the cleaning equipment.

19.汇率和出口
V1  country X提出要重新降低本国货币的汇率来继续增强该国的出口竞争力，然后问下面哪个事实最好地weaken
E 只要通过提高产品本身的质量即使该国货币不贬值，出口也还是会继续增加
V2  第二个版本和第一个选项不同！
汇率和出口那道。几乎一样，选项表述不太相同，但意思就是工厂生产能力已经达到极限

考古：
说货币贬值的时候，就会刺激出口，举了两个例子，但是说这个国家要让货币贬值，它的出口也不会增加。我选的他现有的工厂已经全负荷生产了，而盖新工厂要几年的时间，他提供不了出口的货物。
答案和以前的题目很像，换了种说法：现在生产出口商品的厂子都满负荷了，新的厂子要一年以后才能投入生产。

GWD-24-14  题干类似，选项不同，大家小心
In 1983 Argonia’s currency, the argon, underwent a reduction in value relative to the world’s strongest currencies. This reduction resulted in a significant increase in Argonia’s exports over 1982 levels. In 1987 a similar reduction in the value of the argon led to another increase in Argonia’s exports. Faced with the need to increase exports yet again, Argonia’s finance minister has proposed another reduction in the value of the argon.

Which of the following, if true, most strongly supports the prediction that the finance minister’s plan will not result in a significant increase in Argonia’s exports next year?

A. The value of the argon rose sharply last year against the world’s strongest currencies.
B. In 1988 the argon lost a small amount of its value, and Aronian exports rose slightly in 1989.
C. The value of Argonia’s exports was lower last year than it was the year before.
D. All of Argonia’s export products are made by factories that were operating at full capacity last year, and new factories would take years to build. 虽采用该计划，惟有利结果已到达极限无法再增加
E. Reductions in the value of the argon have almost always led to significant reductions in the amount of goods and services that Argonians purchase from abroad.

PREP1-25.        (30261-!-item-!-188;#058&004144)
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) After several decades of operating well below peak capacity, Darfir's manufacturing sector is now operating at near-peak levels. 虽采用该计划，惟有利结果已到达极限无法再增加
(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.

17.机场延误与座位        两个不同版本
V1：机场5年内，关于飞机延误的抱怨变多了，关于座位的抱怨不多，座位状况保持不变，那么关于座位的抱怨不会增加。weaken 人在烦躁的时候会找座位的毛病。

V2past 5 years抱怨率飙升，有关于delay本身的，还有抱怨seats cramping的。头说了，公司的座椅并没有变小（这个要注意！JJ貌似说的是加宽过了），因此delay才是问题所在。又因为人们心情恶劣时往往会抱怨相关的事物，所以只要我们解决delay问题保证准点，就不会有更多的complain啦。问weaken
选项1：公司现在的flights比过去5年间要多了许多
选项2：公司之前才加宽了座椅间距，从XX到XX
选项3：貌似是某研究证明，顾客情绪是不会受XX影响之类的      有人说没有这个选项 到时候自己看吧
需要削弱的是不会再有人投诉，其措施是不晚点，那么即使不晚点也会有人投诉就是其切入点，方向：目前的顾客流量超过了扩宽的座位数，这样也座位也是有关的。
