Q28:
Wind farms, which generate electricity using arrays of thousands of wind-powered turbines, require vast expanses of open land. County X and County Y have similar terrain, but the population density of County X is significantly higher than that of County Y. Therefore, a wind farm proposed for one of the two counties should be built in County Y rather than in County X.
风力农场通过数千个风力涡轮机来发电，所以需要非常宽阔的开放场地。X国和Y国有相近的地形，但是X国的人口密度却明显高于Y国。因此风力农场应该选择建在Y国而不是X国。
Which of the following, if true, most seriously weakens the planner’s argument? 找一个理由出来说建在X国的原因。
County X and County Y are adjacent to each other, and both are located in the windiest area of the state. 就是说建在哪儿都差不多，这可不是大家期望的答案。
The total population of County Y is substantially greater than that of County X. Y国的人会逐渐比X国多。那就是以后的事，我们谈的是现在建在哪儿更好。
Some of the electricity generated by wind farms in County Y would be purchased by users outside the county.这儿不需要讨论发了电后的经济问题。谁来买电是没有关系的，再说了建在X国顾客说不定就到X国去买了。
Wind farms require more land per unit of electricity generated than does any other type of electrical-generation facility. 就是说需要更多的地，那为什么X国不行呢?没有答案。
Nearly all of County X’s population is concentrated in a small part of the county, while County Y’s population is spread evenly throughout the country. 其实是Y国才有更宽阔的开放地带。正确。
Q29:
Over the past five years, the price gap between name-brand cereals and less expensive store-brand cereals has become so wide that consumers have been switching increasingly to store brands despite the name brands’ reputation for better quality. To attract these consumers back, several manufacturers of name-brand cereals plan to narrow the price gap between their cereals and store brands to less than what it was five years ago.
在过去五年内，知名的麦片和非名牌的价格差别大得让顾客都去买便宜的那种了，虽然说知名品牌的有着更好质量的口碑。如果要让顾客买名牌的麦片，许多知名品牌麦片生产商决定拉小和非名牌的价格差距(比五年前小)。
Which of the following, if true, most seriously calls into question the likelihood that the manufacturers’ plan will succeed in attracting back a large percentage of consumers who have switched to store brands?
There is no significant difference among manufacturers of name-brand cereals in the prices they charge for their products. 在名牌产品之间价格差别不大。现在讨论的是名牌和非名牌，不关名牌和名牌的事。
Consumers who have switched to store-brand cereals have generally been satisfied with the quality of those cereals.买便宜麦片的顾客普遍对其质量满意。从题干看，两者的差别一是质量，二是价格。前者对名牌有利，后者对非名牌有利。而这个选项连质量这个优势也给否定了。正确。
Many consumers would never think of switching to store-brand cereals because they believe the name brand cereals to be of better quality. 这部分顾客不是需要争取回来的顾客，所以无关。
Because of lower advertising costs, stores are able to offer their own brands of cereals at significantly lower prices than those charged for name-brand cereals.就是说便宜可以更便宜，但是题干并没有说名牌的会便宜到什么程度，完全可能便宜到和非名牌(在其再度降价后)差不了太多的程度。还有一个问题是，可以更便宜不等于已经更便宜。
Total annual sales of cereals—including both name-brand and store-brand cereals—have not increased significantly over the past five years. 名牌的生产商要争取的是现有的消费人群的消费力，并不涉及新的消费力。无关。
Q30:
Which of the following most logically completes the argument?
The irradiation of food kills bacteria and thus retards spoilage. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking. However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______.
这种照射食物(处理方法)杀死了细菌从而延缓了食物变质。但是它也降低了食品中的一些营养价值。比如照射线毁坏了食品中所含的大部分维B1，但是提倡这种食品处理方法的人却说在这方面，烹调食物有同样的结果。但是事实是这样的话要么是不切重点，因为大部分照射处理的食物是生吃的，要么就是误导。。。。。。
many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life 这个作用地球人都知道了，重复题干是没有意义的。
it is clear that killing bacteria that may be present on food is not the only effect that irradiation has 但是这个作用不是没有的，所以只可能说没说完全，但不是误导。
cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods 目的不同，不能说是误导。
certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is 那就不仅不是误导，反而说得不到位了。但我们现在要证明他是在误导，所以这个错。
for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded 就是说损失是加倍的。但如果不知道这个事实就以为反正烹调也会破坏维B1，也就是说这个破坏是避免不了的，那给谁破坏都是破坏，无所谓了。可事实是破坏虽然是不可避免的，可是可以选择被破坏X还是2X. 存在误导，所以正确。
Q32:GWD-4-8
From 1980 to 1989, total consumption of fish in the country of Jurania increased by 4.5 percent, and total consumption of poultry products there increased by 9.0 percent. During the same period, the population of Jurania increased by 6 percent, in part due to immigration to Jurania from other countries in the region.
从1980到1989年，J国的鱼消费量(是被吃的鱼，我怎么写得象鱼花的钱呢?)增加了4.5%，而禽的消费量增加了9个百分点。在同期间，J国的人口增加了6个百分点，部分是从其它国家迁来的移民。
If the statements above are true, which of the following must also be true on the basis of them?
During the 1980’s in Jurania, profits of wholesale distributors of poultry products increased at a greater rate than did profits of wholesale distributors of fish. 整题没有一句说到利润的事，不能推出卖得多就赚得多。
For people who immigrated to Jurania during the 1980’s, fish was less likely to be a major part of their diet than was poultry. 谁说那多卖出去的禽就是我们移民吃的?
In 1989 Juranians consumed twice as much poultry as fish.因为不知道基数，所以不能推出禽类被吃的总量是不是超过被吃的鱼一倍。
For a significant proportion of Jurania’s population, both fish and poultry products were a regular part of their diet during the 1980’s.谁说蔬菜就不能是J国的主要食物呢?只从两种食品的百分比增加不能推出其它食品就吃得比这两种少。
Per capita consumption of fish in Jurania was lower in 1989 than in 1980. 通过列算术式就知道是这个了。
Q33:
Wolves generally avoid human settlements. For this reason, domestic sheep, though essentially easy prey for wolves, are not usually attacked by them. In Hylantia prior to 1910, farmers nevertheless lost considerable numbers of sheep to wolves each year. Attributing this to the large number for wolves, in 1910 the government began offering rewards to hunters for killing wolves. From 1910 to 1915, large numbers of wolves were killed. Yet wolf attacks on sheep increased significantly.
狼一般会避免人们居住的地方。正是这个原因，家养的羊，尽管是狼最容易捕食的动物，但却不是经常受到狼的袭击。但是在1910年前，H地的农民的羊每年都被狼逮走不少。人们归因于狼太多了，所以1910-1915年间，政府组织去杀狼。结果是狼被杀了不少，但狼攻击羊的事却发生的更多了。
Which of the following, if true, most helps to explain the increase in wolf attacks on sheep?
Populations of deer and other wild animals that wolves typically prey on increased significantly in numbers from 1910 to 1915. 那就应该不来吃羊才对呀，错误。
Prior to 1910, there were no legal restrictions in Hylantia on the hunting of wolves.不能解释为什么狼被杀了不少，来吃羊的狼却增加了不少这个现象。
After 1910 hunters shot and wounded a substantial number of wolves, thereby greatly diminishing these wolves’ ability to prey on wild animals.因为被打伤了，吃不了野生的动物，所以只有来欺负老实的羊。包括了题干中的两个事实(打狼、吃羊)，典型的正确答案。
Domestic sheep are significantly less able than most wild animals to defend themselves against wolf attacks.羊容易被吃这个是早就存在的事实，我知道，你知道，1910前的狼也知道。
The systematic hunting of wolves encouraged by the program drove many wolves in Hylantia to migrate to remote mountain areas uninhabited by humans.狼跑远了，吃羊的狼也应该是变少了才对。不能解释。
Q38:
Nitrogen dioxide is a pollutant emitted by automobiles. Catalytic converters, devices designed to reduce nitrogen dioxide emissions, have been required in all new cars in Donia since 1993, and as a result, nitrogen dioxide emissions have been significantly reduced throughout most of the country. Yet although the proportion of new cars in Donia’s capital city has always been comparatively high, nitrogen dioxide emissions there have showed only an insignificant decline since 1993.
氮二氧化物是则汽车散发出来的污染源。催化转化器是设计来降低氮二氧化物散发量的。在D国，从1993年就起就要求所有的新车安装这种转化器。D国的氮二氧化物散发量的确大幅度减少了。但是尽管D国首都的新车比例是高的，1993年后首都的氮二氧化物散发量却没有明显的降低。
Which of the following, if true, most helps to explain the insignificant decline in nitrogen dioxide emissions in Donia’s capital city?
More of the cars in Donia’s capital city were made before 1993 than after 1993题干中看出首都的新车比例比其它城市都高，那其它地方的污染都降下来了，首都也应该降才对呀，哪怕旧车比新车多(其它地方的旧车应该更多)。所以没能解释问题
The number of new cars sold per year in Donia has declined slightly since 1993.1993年后新车卖出去的少了。
Pollutants other than nitrogen dioxide that are emitted by automobiles have also been significantly reduced in Donia since 1993. 其它污染源被控制不住对题目都不起解释作用。
Many Donians who own cars made before 1993 have had catalytic converters installed in their cars.一，讨论的是D的首都，而不是D全国。二，有转换器的车其实挺多了，那为什么反而不起作用呢?错误。
Most car trips in Donia’s capital city are too short for the catalytic converter to reach its effective working temperature.这就是了，尽管安装了，但是没用，相当于没安。正确答案。
Q40: GWD-4-20
Community activist: If Morganville wants to keep its central shopping district healthy, it should prevent the opening of a huge SaveAll discount department store on the outskirts of Morganville. Records from other small towns show that whenever SaveAll has opened a store outside the central shopping district of a small town, within five years the town has experienced the bankruptcies of more than a quarter of the stores in the shopping district.
如果V地要想保持它的中心购物区的良性发展，那就避免阻止那个大型的折扣店S在V地开店。从其它小型城市的报告看，只要S在哪个地方的中心商业区外开了店，那个地区的中心商业区在五年内就会有超过四分之一的商店关门。
The answer to which of the following would be most useful for evaluating the community activist’s reasoning?
Have community activists in other towns successfully campaigned against the opening of a SaveAll store on the outskirts of their towns? 其它地区有没有成功阻止S开店不是问题，现在的问题是要不要阻止它开店，而不是阻止得成它开店不。
Do a large percentage of the residents of Morganville currently do almost all of their shopping at stores in Morganville? 人们在哪里买东西不能是评价这个提议的依据。人们现在在这儿买不等于以后就不在这儿买。
In towns with healthy central shopping districts, what proportion of the stores in those districts suffer bankruptcy during a typical five-year period?这个就对了，或如果开没开S店，都会有超过1/4的店关门大吉，那这个就不关S店的事。但是如果没开S店，商业关门率比1/4低得多，那就说明S店的确影响了一个地区的经济。
What proportion of the employees at the SaveAll store on the outskirts of Morganville will be drawn from Morganville?题干没有说关门是因为店员都跑到S店去打工了，所以无关。
Do newly opened SaveAll stores ever lose money during their first five years of operation? S店赚不赚钱不是这个作者想关心的事，也不是我们应该关心的事。
