Which of the following most logically completes the argument below?
Davison River farmers are currently deciding between planting winter wheat this fall or spring wheat next spring. Winter wheat and spring wheat are usually about equally profitable. Because of new government restrictions on the use of Davison River water for irrigation, per acre yields for winter wheat, though not for spring wheat, would be much lower than average. Therefore, planting spring wheat will be more profitable than planting winter wheat, since‗‗‗‗‗‗.
A. the smaller-than-average size of a winter wheat harvest this year would not be compensated for by higher winter wheat prices 收入不足以抵消支出
B. new crops of spring wheat must be planted earlier than the time at which standing crops of winter wheat are ready to be harvested
C. the spring wheat that farmers in the Davison River region plant is well adapted to the soil of the region
D. spring wheat has uses that are different from those of winter wheat
E. planting spring wheat is more profitable than planting certain other crops, such as rye [A]作者: xiongbaobao 时间: 2010-10-19 12:01

Which of the following most logically completes the passage below?
Heavy rains during Centralia’s corn planting season prevented some farmers there from planting corn. It is now the planting season for soybeans, another of Centralia’s principal crops, and those fields originally intended for corn are dry enough for planting. Nonetheless, even though soybean prices are unusually high at present, the farmers will leave most of these fields empty rather than plant them with soybeans, since ‗‗‗‗‗‗.
A. the extensive rains have led to an increase in the price of corn （留空地不种大豆不代表就种玉米，而且现在不是玉米季）
B. some Centralian farmers anticipate serious financial losses due to the extremely wet spring planting season
C. chemicals that were used to prepare the fields for corn planting would stunt the growth of soybeans
D. the majority of Centralia’s corn farmers were able to plant corn as they had intended, despite the wet planting season
E. many Centralian farmers grow both corn and soybeans [C]*作者: xiongbaobao 时间: 2010-10-19 12:01
GWD-2-Question 12:（OG12th中22题的变体）
Which of the following most logically completes the passage?
Concerned about financial well-being of its elderly citizens, the government of Runagia
decided two years ago to increase by 20 percent the government-provided pension
paid to all Runagians over 65. Inflation in the intervening period has been negligible,
and the increase has been duly received by all eligible Runagians. Nevertheless,
many of them are no better off financially than they were before the increase, in large
part because ________.
把老人收入来源分割成：政府补贴+孩子的补贴。
A. They rely entirely on the government pension for their income
B. Runagian banks are so inefficient that it can take up to three weeks to cash a
pension check
C. They buy goods whose prices tend to rise especially fast in times of inflation（相近于OG中的正确选项，但是此题选项是especially fast不是faster，不能表现出OG中指的这些特殊商品及服务的价格涨得比平均通胀快，只能因为这题中提到的negligible inflation而排除）
D. The pension was increased when the number of elderly Runagians below the
poverty level reached an all-time high
E. In Runagia children typically supplement the income of elderly parents, but
only by enough to provide them with a comfortable living
If E, "...children typically supplement the income of elderly parents, but only by enough to provide them with a comfortable living," is true, then government's pension increase will be offset by lower income supplement from children, and the elders' total income (gov. pension + children's supplement) will stay the same. So, E provides a good explanation to complete the original passage.
换言之，子女给父母的补助是看情况定的，刚够用就为止了，所以政府补贴多，他们就补贴少，导致老年人的总体收入没有大的变化。作者: xiongbaobao 时间: 2010-10-19 13:18
GWD-2-Q12:
Which of the following most logically completes the argument?
Yorco and Zortech are two corporations that employ large numbers of full-time workers who are paid by the hour. Publicly available records indicate that Yorco employs roughly the same number of such hourly wage workers as Zortech does but spends a far higher total sum per year on wages for such workers. Therefore, hourly wages must be higher, on average, at Yorco than at Zortech, since _____.
按时付工资
Y和Z的工人数一样
Y比Z负的总工资数多。
结论，Y的每小时工资多。
自己推：小时数一样。就只找和时间有关的名词
A. Zortech spends a higher total sum per year than Yorco does to provide its hourly wage workers with benefits other than wages
B. the work performed by hourly wage workers at Zortech does not require a significantly higher level of skill than the work performed by hourly wage workers at Yorco does
C. the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech
D. overtime work, which is paid at a substantially higher rate than work done during the regular work week, is rare at both Yorco and Zortech（排除他因）
E. the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech作者: xiongbaobao 时间: 2010-10-19 13:18

Which of the following most logically completes the argument?
A new drug, taken twice daily for one month, is an effective treatment for a certain disease. The drug now most commonly prescribed for the disease occasionally has serious side effects such as seizures; in field tests, the new drug’s side effects, though no worse than mild nausea, turned out to be much more frequent. Nevertheless, the new drug is clearly preferable as a treatment, since _____.
A. people who experience nausea are prone to discontinue use of the new drug prematurely
B. …

GWD-3-Q8:
Which of the following most logically completes the passage?
Garnet and RenCo each provide health care for their employees. Garnet pays for both testing of its employees’ cholesterol levels and treatment of high cholesterol. This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment. However, RenCo dose not have the same financial incentive to adopt such a policy, because ______.
胆固醇过高多年不治的话拖久了治疗费用很贵，所以G支付员工测试胆固醇以及治疗胆固醇过高的费用其实节省了资金。
但R无需效仿。。。
A. early treatment of high cholesterol dose not entirely eliminate the possibility of a stroke later in life
B. the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol
C. RenCo has significantly more employees than Garnet has
D. RenCo’s employees are unlikely to have higher cholesterol levels than Garnet’s employees（R的员工不会比G的员工得更严重的胆固醇。如果R也已经是严重的了，仍然要付昂贵的医药费，只是比G少点，不足以支持不用负担的理论）
E. the average length of time an employee stays with RenCo is less than it is with Garnet [E]（因为R的员工在公司工作时间少，则发病的时很可能已经离开公司了，R不用为其医药费买单）作者: xiongbaobao 时间: 2010-10-19 13:22
GWD-3-Q18:
Which of following most logically completes the argument?
The last members of a now-extinct species of a European wild deer called the giant dear lived in Ireland about 16,000 years ago. Prehistoric cave paintings in France depict this animal as having a large hump on its back. Fossils of this animal, however, do not show any hump. Nevertheless, there is no reason to conclude that the cave paintings are therefore inaccurate in this regard, since ______. 壁画上该鹿有hump，化石上该鹿没有hump，但壁画是对的。
解释题型：为何化石上的该鹿没有了hump
A. some prehistoric cave paintings in France also depict other animals as having a hump
B. fossils of the giant deer are much more common in Ireland than in France
C. animal humps are composed of fatty tissue, which dose not fossilize
D. the cave paintings of the giant deer were painted well before 16,000 years ago
E. only one currently existing species of deer has any anatomical feature that even remotely resembles a hump [C]作者: xiongbaobao 时间: 2010-10-19 13:22
GWD-5-Q30: OG12th 99题
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 _______.
A. many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life
B. it is clear that killing bacteria that may be present on food is not the only effect that irradiation has
C. cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods
D. certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is
E. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded[E]
compound的意思不是分不清，而是混合加成，作者想要指出的是，i的支持者们误导消费者去比较i和c的作用，而不是关注如何减少总的作用。c不存在i存在（生吃i过的），i单独作用，c就无关，比较i,c是beside the point。c,i同时存在，i,c的作用混合发生，比较i,c这两个组成部分之间的大小是对判断总量的一种misleading。
1．no worse than不是not worse than， 这里可以把no worse than理解为as great as，as much as，as significant as。所以这个fact的表述应该是没有问题的。就是说irradiation和cooking在这一点上差不多，可能i>c or i<c,并不是i>=c(i not worse than c).
2， 这一题的关键还是beside the point和misleading，就是离题(或无关）和误导。C只是说明了无关（也就是离题），并没有说明误导。只有E说明了误导。
原因：proponent说irradiation和cooking在这一点上差不多。潜在的意思（误导的结论）是说不管有没有irradiation后，损失的营养是差不多的。这就是误导，不合逻辑的。E就是说明了这个显然的误导，因为2个行为在这一点上的效果是有可能叠加的。
只有E针对了这个误导的结论。其实就是要看误导的结论是什么。C和这个误导的结论无关作者: xiongbaobao 时间: 2010-10-19 13:23
GWD-5-Q32:
Which of the following most logically completes the argument?
Although the pesticide TDX has been widely used by fruit growers since the early 1960’s, a regulation in force since 1960 has prohibited sale of fruit on which any TDX residue can be detected. That regulation is about to be replaced by one that allows sale of fruit on which trace amounts of TDX residue are detected. In fact, however, the change will not allow more TDX on fruit than was allowed in the 1960’s, because ______.
A. pre-1970 techniques for detecting TDX residue could detect it only when it was present on fruit in more than the trace amounts allowed by the new regulations。原先能够检测出的最低含量比新规定的量多。
B. many more people today than in the 1960’s habitually purchase and eat fruit without making an effort to clean residues off the fruit
C. people today do not individually consume any more pieces of fruit, on average, than did the people in the 1960’s
D. at least a small fraction of the fruit sold each year since the early 1960’s has had on it greater levels of TDX than the regulation allows
E. the presence of TDX on fruit in greater than trace amounts has not been shown to cause any harm even to children who eat large amounts of fruit[A]
以前，监测到有RESIDUE就不能卖，新规定允许有trace amounts 。（虽然说条件放宽了），但较松的规定却没有让更多的苹果通过监测。A说的是原来的技术其实单纯的RESIDUE是检查不出来的，只有到了TDX的量高于trace amounts ，才能检查成有RESIDUE。这样虽然条件放宽了，但技术水平使实际检查到的TDX的量是差不多的。所以说较松的规定却没有让更多的苹果通过监测。作者: xiongbaobao 时间: 2010-10-19 13:24

A brochure from the largest hotel in Harristown claims that more tourists stay in that hotel than stay in the Royal Arms Hotel in Springfield. If both of these sources are accurate, however, the county’s “Report on Tourism” must be in error in indicating that _______.
A. more tourists stay in hotel accommodations in Harristown than stay in the Royal Arms Hotel
B. the Royal Arms Hotel is the only hotel in Springfield
C. there are several hotels in Harristown that are larger than the Royal Arms Hotel
D. some of the tourists who have stayed in hotels in Harristown have also stayed in the Royal Arms Hotel

GWD-7-Q21:
Which of the following most logically completes the passage?
Each species of moth has an optimal body temperature for effective flight, and when air temperatures fall much below that temperature, the moths typically have to remain inactive on vegetation for extended periods, leaving them highly vulnerable to predators. In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why ______.
外部温度小于体温时----不能达到effective fight----inactive in vegetation
大的M飞得快，但需要的体温也高----外部温度也要高
A. large moths are generally able to maneuver better in flight than smaller moths
B. large moths are proportionally much more common in warm climates than in cool climates（根据文意给出线索推论，而不是发散出没提到过的他因）
C. small moths are more likely than large moths to be effectively camouflaged while on vegetation
D. large moths typically have wings that are larger in proportion to their body size than smaller moths do
E. most predators of moths prey not only on several different species of moth but also on various species of other insects作者: xiongbaobao 时间: 2010-10-19 13:25
GWD-9-Q20:
Which of the following most logically completes the reasoning?
Either food scarcity or excessive hunting can threaten a population of animals. If the group faces food scarcity, individuals in the group will reach reproductive maturity later than otherwise. If the group faces excessive hunting, individuals that reach reproductive maturity earlier will come to predominate. 比较生育成熟年龄Therefore, it should be possible to determine whether prehistoric mastodons became extinct because of food scarcity or human hunting, since there are fossilized mastodon remains from both before and after mastodon populations declined, and ______.
A. there are more fossilized mastodon remains from the period before mastodon populations began to decline than from after that period
B. the average age at which mastodons from a given period reached reproductive maturity can be established from their fossilized remains
C. it can be accurately estimated from fossilized remains when mastodons became extinct
D. it is not known when humans first began hunting mastodons
E. climate changes may have gradually reduced the food available to mastodons[B]
答案为B
原文知两个关系：如果FACE FOOD SCARCITY，则慢到reproductive maturity 。如果FACE EXCESSIVE HUNTING，则早到reproductive maturity （早到reproductive maturity 的占大多数）。
所以作者认为有可能确定M是由于FOOD SCARCITY灭绝，还是EXCESSIVE HUNTING灭绝。理由是有M数量减少前后的化石。另外，B说可从化石知道到达reproductive maturity 的平均年龄。因为如果减少前的reproductive maturity 年龄大于减少后的年龄，则原因是EXCCESIVE HUNTING（根据第二个关系）。如果小于，则是FOOD SCARCITY（第一个关系）作者: xiongbaobao 时间: 2010-10-19 13:26
GWD-10-Q15
Which of the following most logically completes the argument below?
Although the number of large artificial satellites orbiting the Earth is small compared to the number of small pieces of debris in orbit, the large satellites interfere more seriously with telescope observations because of the strong reflections they produce. Because many of those large satellites have ceased to function, the proposal has recently been made to eliminate interference from nonfunctioning satellites by exploding them in space. This proposal, however, is ill conceived, since _______.
大卫星比Debris小，但阻碍天文望远镜观察。
建议引爆所有不工作的大卫星。目的更好的观察。
目的无法实现：不能够更好的观察了
A. many nonfunctioning satellites remain in orbit for years
B. for satellites that have ceased to function, repairing them while they are in orbit would be prohibitively expensive（因为修贵所以炸掉好，反而支持这个计划了）
C. there are no known previous instances of satellites’ having been exploded on purpose
D. the only way to make telescope observations without any interference from debris in orbit is to use telescopes launched into extremely high orbits around the Earth（虽然前半部分理由没错，但要否决某计划不好应该先说为什么这个计划不好，而不是说另一个计划更好）
E. a greatly increased number of small particles in Earth’s orbit would result in a blanket of reflections that would make certain valuable telescope observations impossible

Which of the following most logically completes the passage?
A certain tropical island received food donations in the form of powdered milk for distribution to its poorest residents, who were thought to be malnourished. Subsequently, the rate of liver cancers among those islanders increased sharply. The donated milk was probably to blame: recent laboratory research on rats has shown that rats briefly exposed to the substances （新概念）aflatoxin tend to develop liver cancer when fed casein, a milk protein. This result is relevant because _______.
前后发生----》因果关系（过渡条件由答案给出）
原因支持：aflatoxin----liver cancer
A. in the tropics, peanuts, a staple of these island residents, support a mold growth that produces aflatoxin？（解释了为什么aflatoxin会出现在牛奶引起的肝癌反应中）

Which of the following most logically completes the argument?
Researchers recently asked dozens of shoppers, chosen at random coming out of a FoodBasket supermarket, what they had purchased. The prices of the very same items at the nearest ShopperKing supermarket were totaled and compared with the FoodBasket total. The ShopperKing totals averaged five percent higher than the FoodBasket totals. Nevertheless, this result does not necessarily show that shoppers at ShopperKing would save money overall by shopping at FoodBasket instead, since ______.
同样商品的价格总和：S>F
但是在F买东西未必比在S买省钱。
A. shoppers who shop regularly at a given supermarket generally choose that store for the low prices offered on the items that they purchase most often（消费者总是买最低价，所以比总价没有意义）
B. for shoppers with more than 20 items, the ShopperKing totals averaged more than five percent higher than the FoodBasket totals 要说明问题这个样本不具代表性
C. many shoppers consider factors other than price in choosing the supermarket at which they shop most regularly
D. there is little variation from month to month in the overall quantity of purchases made at supermarkets by a given shopper
E. none of the people who conducted the research were employees of the FoodBasket supermarket
文中最后一句话的意思是通常在SK购物的人到FB去购物未必会省钱，因为：
A. 消费者通常到选定这样一个超市，他们最频繁购买的东西在那家的超市里的价格是最低的。
具体的说，假如有商品A,B,C,D,E。
在SK超市里A,B,C的价格比FB超市低。而FB超市里D,E的价格又比SK里的低。
那么假如一个消费着经常需要消费A,B,C商品，所以他会选SK超市，因为他到FB超市去买的话A,B,C反而贵，符合文中最后一句话。作者: xiongbaobao 时间: 2010-10-19 13:28

Which if the following, if true, most logically completes the argument?
Aroca County’s public schools are supported primarily by taxes on property. The county plans to eliminate the property tax and support schools with a new three percent sales tax on all retail items sold in the county. Three percent of current retail sales is less than the amount collected through property taxes, but implementation of the plan would not necessarily reduce the amount of money going to Aroca County public schools, because ______.
A. many Aroca County residents have already left the county because of its high property taxes（支持新计划应该先提出它好在哪里和可行性，而不是提原本的政策不好在哪里）
B. a shopping mall likely to draw shoppers from neighboring counties is about to open in Aroca County
C. at least some Aroca County parents are likely to use the money they will save on property taxes to send their children to private schools not funded by the county
D. a significant proportion of parents of Aroca County public school students do not own their homes and consequently do not pay property taxes

Which of the following most logically completes the argument below?
The expansion of large-scale farming in Africa and Asia has destroyed much of the natural vegetation on which elephants have historically depended, forcing them to turn to cultivated land to satisfy their enormous appetites. As a result, farmers have lost millions of dollars worth of crops annually. Yet even if elephant sanctuaries（自然保护区） were created on a widespread basis to guarantee elephants sufficient natural vegetation, the raiding would likely persist, since
即使提供大象足够的自然植被，他们仍会侵略耕地
A. when elephants forage for food, they typically travel in herds.范围太大不够具体
B. Foraging elephants have been known to cause substantial damage even to plants that they do not eat.范围太大
C. Some of the land where crops have suffered extensive damage from elephants has been allowed to return to its natural state.
D. Elephants tend to prefer cultivated crops to wild vegetation as a food source.
E. Elephant sanctuaries are usually created in areas that are rich in the natural vegetation on which elephants have historically depended.好像是在说大象应该会转向自然植被。与文中不符合
