GWD7-Q37:（CD-5-37） 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?
A. The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it. B. Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than they otherwise would. C. Some people who ate meat regularly in the past are converting to diets that include little or no meat. D. As meat prices rise, the number of livestock producers is likely to rise again. E. Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past. 选B
PREP里面的 The country of Baurisia has, until now, been self-sufficient in both grain and meat.However, with growing prosperity in Baurisia has come a steadily increasing per capita consumption of meat, and it takes several pounds of grain to produce one pound of meat.Therefore, since per capita income in Baurisia is almost certain to rise further but increases in domestic grain production are highly unlikely, Baurisia is soon likely to become an importer of grain. Which of the following, if true, most seriously weakens the argument?
A. When people increase their consumption of meat, they also tend to increase their consumption of grain. B. The per capita consumption of meat in Baurisia is roughly the same across all income levels. C. Per capita consumption of meat has not increased substantially in recent years in those countries from which Baurisia is likely to import meat. D. It is more economical for Baurisians to import meat than grain. E. During Baurisia's years of growing prosperity, the country's population has remained relatively stable. 选D

In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher.Part of this effort has been to deny inmates the access they formerly had to college-level courses.However, this action is clearly counter to the governor’s ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates.
Which of the following is an assumption on which the argument depends?
Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.
Former inmates are no more likely to commit crimes than are members of the general population.
The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released.
Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.
The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.
（后来我发现更加像这一道……GWD上关于crime rate的就这两道了。）
The violent crime rate (number of violent crimes per 1,000 residents) in Meadowbrook is 60 percent higher now than it was four years ago. The corresponding increase for Parkdale is only 10 percent. These figures support the conclusion that residents of Meadowbrook are more likely to become victims of violent crime than are residents of Parkdale.
The argument above is flawed because it fails to take into account
Changes in the population density of both Meadowbrook and Parkdale over the past four years.
How the rate of population growth in Meadowbrook over the past four years compares to the corresponding rate for Parkdale
The ratio of violent to nonviolent crimes committed during the past four years in Meadowbrook and Parkdale
The violent crime rates in Meadowbrook and Parkdale four years ago
How Meadowbrooks’ expenditures for crime prevention over the past four years compare to Parkdale’s expenditures.
In each of the past five years, Barraland’s prison population has increased.Yet, according to official government statistics, for none of those years has there been either an increase in the number of criminal cases brought to trial, or an increase in the rate at which convictions have been obtained.Clearly, therefore, the percentage of people convicted of crimes who are being given prison sentences is on the increase.
Which of the following, if true, most seriously weakens the argument?
In Barraland the range of punishments that can be imposed instead of a prison sentence is wide.
Over the last ten years, overcrowding in the prisons of Barraland has essentially been eliminated as a result of an ambitious program of prison construction.
Ten years ago, Barraland reformed its criminal justice system, imposing longer minimum sentences for those crimes for which a prison sentence had long been mandatory.
Barraland has been supervising convicts on parole more closely in recent years, with the result that parole violations have become significantly less frequent.
The number of people in Barraland who feel that crime is on the increase is significantly greater now than it was five years ago.
