Crowding on Mooreville’s subway frequently leads to delays, because it is difficult for passengers to exit from the trains. Subway ridership is projected to increase by 20 percent over the next 10 years. The Mooreville Transit Authority plans to increase the number of daily train trips by only 5 percent over the same period. Officials predict that this increase is sufficient to ensure that the incidence of delays due to crowding does not increase.

Which of the following, if true, provides the strongest grounds for the officials’ prediction?

黑体字： Delta Products Inc. has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity. The question has been raised whether it can be concluded that 黑体字: for a give level of output Delta's operation now causes less fossil fuel to be consumed than it did formerly. The answer, clearly , is year, since the amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount needed to power the older technologies, provided level of output is held constant. In the argument given, the two boldfaced portions play which of the following roles? A. The first identifies the content of the conclusion of the argument; the second provides support for that conclusion. B. The first provides support for the conclusion of the argument; the second identifies the content of that conclusion. 答案是B。 我的想法：老师，这道题我非常不理解B，我选的A。 抛出第一个黑体字不说，第二个怎么看也不像identifies the content of that conclusion.啊？ 我换个通俗一点的说法麻烦老师看一下，这篇文章可以这么说： 1. （黑体字）英吉打管卫东 2. the question has been raised whether it can be concluded that (黑体字）英吉喝水 3. the answer is year since....... 我不知道我这么陈述合适否，但如果合适，条件黑体1难道不是结论么？条件黑体2难道不是支持这个结论的么？困扰了我很久，谢谢老师

The imposition of quotas limiting imported steel will not help the big American steel mills.  In fact, the quotas will help "mini-mills" flourish in the United States.  Those small domestic mills will take more business from the big American steel mills than would have been taken by the foreign steel mills in the absence of quotas.
Which of the following, if true, would cast the most serious doubt on the claim made in the last sentence above?

Traveler:  Southern Airways has a far worse safety record than Air Dacentaria over the past few years, in terms of both the frequency of accidents and the severity of accidents.  Therefore, although Air Dacentaria is slightly more expensive, I will choose it over Southern Airways for my flight from Pederton to Dacenta, since it is worth paying extra to have a safer flight.
 
Which of the following, if true, casts the most serious doubt on the traveler's argument?
题干问质疑TRAVELER'S ARGUMENT. 的范围是我从P到D选择哪个航班更安全，多花一点钱也是值得的。 我思考的角度是，既然是质疑，那么 1. 不应该选择 air dacentaria over southern airways for my flight from P to D. 或者 2. it is not worth paying extra to have a safer flight. 换句话说，答案是反驳travelers' argument,或者说这2个公司差不多，或者说那个出事的其实没那么危险 答案是B，我不太明白，B的范围说的是除了P到D，那个经常出事的公司SOUNTHERN经常降落另外一个飞机场，然后那个飞机场有世界上最危险的山。 我当时几乎把5个全排除了，想问一下老师B凭什么留下来？

In parts of South America, vitamin-A deficiency is a serious health problem, especially among children.  In one region, agriculturists are attempting to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in beta-carotene, which the body converts into vitamin A.  The plan has good chances of success, since sweet potato is a staple of the region's diet and agriculture, and the varieties currently grown contain little beta-carotene.
 
Which of the following, if true, most strongly supports the prediction that the plan will succeed?

Tiger sharks are common in the waters surrounding Tenare Island.  Usually tiger sharks feed on smaller sharks, but sometimes they have attacked tourists swimming and surfing at Tenare's beaches.  This has hurt Tenare's tourism industry, which is second only to its fishing industry in annual revenues.  In order to help the economy, therefore, the mayor of the island has proposed an ongoing program to kill any tiger sharks within a mile of the beaches.
 
Which of the following, if true, most strongly calls into question the likelihood that implementation of the mayor's proposal will have the desired consequence?

Which of the following, if true, most strongly calls into question the likelihood that implementation of the mayor's proposal will have the desired consequence? A.Even if not all the tiger sharks that come close to the beaches are killed, the existence of the program would reassure tourists. B. Business owners who depend on tourism are willing to pay most of the cost of implementing the program. C. Tourists come to Tenare Island for its beaches, even though the island features a number of other tourist attractions. D.The small sharks on which tiger sharks prey feed on fish that are commercially important to the island's fisheries. E. Not all tourists who come to Tenare Island enjoy swimming or surfing. 老师解释说了很多，可还是没有说为什么留D不留E啊？ 第一眼看到D，我怎么也想不到跟原文沾边，题干说的是为了保护当地经济，头要杀掉鱼确保游客安全。 D说的一个鱼吃掉一个鱼，什么对于当地有没有经济影响。 E说的是不是所有的游客来这里都是SWIMMING OR SURFING.换句话说，即使你把鱼都杀死了，游客的量也还是不会变，因为不是所有人都来你这来海边的，问题要CALL INTO QUESTION,这不是很好的质疑了么？麻烦老师解答。
