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。

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.

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.
