Tiger sharks are common in thewaters surrounding Tenare Island. Usually tiger sharks feed on smaller sharks, but sometimes they haveattacked tourists swimming and surfing at Tenare's beaches. This has hurt Tenare's tourism industry, which is second only to itsfishing industry in annual revenues. In order to helpthe economy（注意目的是economy，不是保护旅游业), therefore,the mayor of the island has proposed an ongoing program to kill any tiger sharks within a mile of thebeaches.措施
措施：捕杀shark 目的：In order to help the economyEconomy 第二是旅游业，第一是渔业 挽救旅游业，不能影响捕渔业 Breakean：影响了捕渔业
Which of the following, if true,most strongly calls into question the likelihood that implementation of themayor's proposal will have the desired consequence? (A) Even if not all the tigersharks that come close to the beaches are killed, the existence of the programwould reassure tourists. 废话 (B) Business owners who depend ontourism are willing to pay most of the cost of implementing the program. 无关 (C) Tourists come to Tenare Islandfor its beaches, even though the island features a number of other touristattractions. 无关并改变事实 (D) The small sharks on which tigersharks prey feed on fish that are commercially important to the island'sfisheries.影响了渔业 (E) Not all tourists who come toTenare Island enjoy swimming or surfing.无关
又看到了likelihood，那么就是说这个措施有可能达不到目的，但是表面上杀鲨鱼是保护游客的，进而保护旅游业，为什么会影响economy呢？肯定有负面的效应（思路2），到底是怎么产生的负面效应，结合文章给的条件，渔业是经济的第一支柱，所以肯定是影响了渔业，带着这个思路找答案
Scientists are discussing ways toremove excess carbon dioxide from the atmosphere by increasing the amount thatis absorbed by plant life目的. One plan toaccomplish this is to establish giant floating seaweed farms in theoceans措施. When the seaweed plants die,they will be disposed of by being burned for fuel.
目的：利用植物吸收减少二氧化碳 措施：在海上建立plant floating
Which of the following, if true,would indicate the most serious weakness in the plan above? (A) Some areas of ocean in theSouthern Hemisphere do not containsufficient nutrients to support large seaweed farms.无关 (B) When a seaweed plant is burned, it releases anamount of carbon dioxide comparable to the amount it has absorbed in itslifetime.正确 (C) Even if seaweed farms proveeffective, some people willbe reluctant to switch to this new fuel.无关 (D) Each year about seven billiontons of carbon dioxide are released into the atmosphere but only about five billion tons are absorbed byplant life.质疑前提条件 (E) Seaweed farms would make more money byfarming seaweed to sell as nutritional supplements than by farming seaweed tosell as fuel.与money无关
提问中serious weakness直接点出了负面效应影响达到目的，所以不要以直接质疑植物吸收二氧化碳能力的思路去找答案，如果这样去找，那么很容易被选项D所迷惑。负面效应又是什么呢?还是文章的线索：burn to fuel。
Twelve years ago and again fiveyears ago, there were extended periods when the DarfirRepublic's currency, the pundra, was weak: its value was unusually low relative to the world's most stablecurrencies. Both times a weak pundramade Darfir's manufactured products a bargain on world markets, and Darfir'sexports were up substantially. Now somepoliticians are saying that, in order to cause another similarly sized increasein exports（这里一定要注意目的是什么）, the government should allow the pundra to become weak again措施.
Which of the following, if true,provides the government with the strongest grounds to doubt that thepoliticians' recommendation, if followed, will achieve its aim? (A) Several of the politicians nowrecommending that the pundra be allowed to become weak made that samerecommendation before each of the last two periods of currency weakness.无关 (B) After several decades ofoperating well below peak capacity, Darfir's manufacturing sector is nowoperating at near-peak levels. (C) The economy of a countryexperiencing a rise in exports will become healthier only if the country'scurrency is strong or the rise in exports is significant.改变事实 (D) Those countries whosemanufactured products compete with Darfir's on the world market all currentlyhave stable currencies.无关 (E) A sharp improvement in the efficiency of Darfir's manufacturing plants would make Darfir's products abargain on world markets even without any weakening of the pundra relative toother currencies.无关
很多人肯定被这道题绊倒过，我第一次看的时候，就误以为目的是increase in exports，按照这个思路去衡量措施的有效性，让我淹没在了5个选项里，而看到正确答案才注意到还有个similarly sized，大家一定不要忽视任何一个词啊，谬之毫厘，差之千里。回归到similarly sized increase in exports，来衡量“故伎重演”，思路就不一样了，货币的贬值对于出口的刺激是毋庸置疑的，措施失败在于没有造成similarly sized increase，这是为什么吗呢？带着这个思路很快就认出正确答案。
A city plans to attract new citizens with new housing and new facilities such as parks目的, recreation centers, and libraries. One component of the city's plan is to require that developers seeking permission to build this new housing provide these additional facilities at no cost to the city.措施 Which of the following, if true, would point to a possible flaw in the city's plan? (A) Developers would pass along their costs to the buyer, thereby raising the cost of housing units beyond the ability of likely purchasers to afford them.正确 (B) Light, nonpolluting industries have located in the area, offering more jobs and better-paying jobs than do the more-established industries in the area.无关 (C) Other towns and cities nearby have yet to embark on any comparable plans to attract new citizens.无关 (D) Most developers see the extra expense of providing municipal facilities as simply one of the many costs of doing business.相反---加强 (E) Studies show that purchasers of new houses, especially first-time buyers, rank recreational resources as an important factor in deciding to buy a particular house. 废话
这道题直接说flaw，思路一：措施无效。为了用建筑和设施吸引居民，措施确是让建筑商负担公共设施的费用，不能达到目的的原因很明显。
