GWD-11-Q31 视网膜的不同光敏感性
People with a certain eye disorder are virtually unable to see in moderately bright light, which seems to them unbearably intense, since the cells of their retinas are overwhelmed by moderately bright light. These people do, however, show normal sensitivity to most components of dim light. Their retinal cells are also not excessively sensitive to red components of moderately bright light.

The information above best supports which of the following hypotheses about people with the disorder described, if they have no other serious visual problems?
A. In all moderately dim light in which people without the disorder can read large print, people with the disorder cannot read such print.
B. In an otherwise darkened concert hall, these people will see a dimly illuminated red exit sign more clearly than small dim white lights that mark the aisles.
C. These people typically see more acutely at night and in dim light than do most people who do not have the disorder.
D. Eyeglasses that are transparent to red components of light but filter out other components of light help these people see in moderately bright light.
E. These people perceive colors other than red in the same way as do most people who do not have the disorder.

BF GWD 5-19 历史人口统计 但选项和第二个划线部分变了（变成倒数第二句话了）
Historian: In the Drindian Empire, censuses were conducted annually to determine the population of each village. Village census records for the last half of the 1600’s are remarkably complete. This very completeness makes one point stand out; in five different years, villages overwhelmingly reported significant population declines. Tellingly, each of those five years immediately followed an increase in a certain Drindian tax. This tax, which was assessed on villages, was computed by the central government using the annual census figures. Obviously, whenever the tax went up, villages had an especially powerful economic incentive to minimize the number of people they recorded; and concealing the size of a village’s population from government census takers would have been easy. Therefore, it is reasonable to think that the reported declines did not happen.

In the historian’s argument, the two portions in boldface play which of the following roles?
A. The first supplies a context for the historian’s argument; the second acknowledges a consideration that has been used to argue against the position the historian seeks to establish.
B. The first presents evidence to support the position that the historian seeks to establish; the second acknowledges a consideration that has been used to argue against that position.
C. The first provides a context for certain evidence that supports the position that the historian seeks to establish; the second is that position.
D. The first is a position for which the historian argues; the second is an assumption that serves as the basis of that argument.
E. The first is an assumption that the historian explicitly makes in arguing for a certain position; the second acknowledges a consideration that calls that assumption into question.

GWD-1-Q14 煤矿产出
That the application of new technology can increase the productivity of existing coal mines is demonstrated by the case of Tribnia’s coal industry. Coal output per miner in Tribnia is double what it was five years ago, even though no new mines have opened.
Which of the following can be properly concluded from the statement about coal output per miner in the passage?
A. If the number of miners working in Tribnian coal mines has remained constant in the past five years, Tribnia’s total coal production has doubled in that period of time.
B. Any individual Tribnian coal mine that achieved an increase in overall output in the past five years has also experienced an increase in output per miner. 平均数和个别
C. If any new coal mines had opened in Tribnia in the past five years, then the increase in output per miner would have been even greater than it actually was. 总数会增加但平均数不一定增加
D. If any individual Tribnian coal mine has not increased its output per miner in the past five years, then that mine’s overall output has declined or remained constant.和文章无关,不是从文章推出的，In Tribnia the cost of producing a given quantity of coal has declined over the past five years.无关

A. At least one of the shipments sent to Truax Construction last week was specially ordered.
B. At least one of last week’s specially ordered shipments did not consist of building supplies.
C. At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.

GWD-9-Q38 电影院爆米花换油

In January of last year the Moviemania chain of movie theaters started propping its popcorn in canola oil, instead of the less healthful coconut oil that it had been using until then. Now Moviemania is planning to switch back, saying that the change has hurt popcorn sales. That claim is false, however, since according to Moviemania’s own sales figures, Moviemania sold 5 percent more popcorn last year than in the previous year.

Which of the following, if true, most strongly supports the argument against Moviemania’s claim?

A. Total sales of all refreshments at Moviemania’s movie theaters increased by less than 5 percent last year.
B. Moviemania makes more money on food and beverages sold at its theaters than it does on sales of movie tickets.
C. Moviemania’s customers prefer the taste of popcorn popped in coconut oil to that of popcorn popped in canola oil.
D. Total attendance at Moviemania’s movie theaters was more than 20 percent higher last year than the year before.
E. The year before last, Moviemania experienced a 10 percent increase in popcorn sales over the previous year.

GWD-7-Q37 玉米减产，肉降价
Escalating worldwide demand for corn has led to a sharp increase in the market price of corn, and corn prices are likely to remain high. Corn is extensive used as feed for livestock, and because profit margins are tight in the livestock business, many farmers are expected to leave the business. With fewer suppliers, meat prices will surely rise. Nonetheless, observers expect an immediate short-term decrease in meat prices.

Which of the following, if true, most helps to justify the observers’ expectation?







The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it.
Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than they otherwise would.
Some people who ate meat regularly in the past are converting to diets that include little or no meat.
As meat prices rise, the number of livestock producers is likely to rise again.
Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past.

GWD-5-Q26 肺部抗体与含盐量 但问的是削弱. 偶选的是把含盐量降下来, 也不能杀死病菌.

Healthy lungs produce a natural antibiotic that protects them from infection by routinely killing harmful bacteria on airway surfaces. People with cystic fibrosis, however, are unable to fight off such bacteria, even though their lungs produce normal amounts of the antibiotic. The fluid on a0.irway surfaces in the lungs of people with cystic fibrosis has an abnormally high salt concentration; accordingly, scientists hypothesize that the high salt concentration is what makes the antibiotic ineffective.







Which of the following, if true, most strongly supports the scientists’ hypothesis?










When the salt concentration of the fluid on the airway surfaces of healthy people is raised artificially, the salt concentration soon returns to normal.
A sample of the antibiotic was capable of killing bacteria in an environment with an unusually low concentration of salt.
When lung tissue from people with cystic fibrosis is maintained in a solution with a normal salt concentration, the tissue can resist bacteria.
Many lung infections can be treated by applying synthetic antibiotics to the airway surfaces.
High salt concentrations have an antibiotic effect in many circumstances

thanks a lot :D
