1.        GWD-1-Q15:

In parts of South America, vitamin-A deficiency is a serious health problem, especially among children.  In one region, agriculturists are attempting to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in beta-carotene, which the body converts into vitamin A.  The plan has good chances of success, since sweet potato is a staple of the region’s diet and agriculture, and the varieties currently grown contain little beta-carotene.

Which of the following, if true, most strongly supports the prediction that the plan will succeed?

1. The growing conditions required by the varieties of sweet potato currently cultivated in the region are conditions in which SPK004 can flourish.

2. The flesh of SPK004 differs from that of the currently cultivated sweet potatoes in color and texture, so traditional foods would look somewhat different when prepared from SPK004.

3. There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is. 为什么不是排除他因？

4. The varieties of sweet potato currently cultivated in the region contain some important nutrients that are lacking in SPK004.

5. There are other vegetables currently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do.

Newspaper editorial:

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?

1. 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.

2. Former inmates are no more likely to commit crimes than are members of the general population.

3. 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.

4. Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.

5. The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.

3     GWD-6-Q32:

Proposal:  Carbon dioxide and methane in the atmosphere block the escape of heat into space.  So emission of these “greenhouse” gases contributes to global warming.  In order to reduce global warming, emission of greenhouse gases needs to be reduced.  Therefore, the methane now emitted from open landfills should instead be burned to produce electricity.

Objection:  The burning of methane generates carbon dioxide that is released into the atmosphere.

Which of the following, if true, most adequately counters the objection made to the proposal?

1. Every time a human being or other mammal exhales, there is some carbon dioxide released into the air.

2. The conversion of methane to electricity would occur at a considerable distance from the landfills.

3. The methane that is used to generate electricity would generally be used as a substitute for a fuel that does not produce any greenhouse gases when burned.

4. Methane in the atmosphere is more effective in blocking the escape of heat from the Earth than is carbon dioxide.

5. The amount of methane emitted from the landfills could be reduced if the materials whose decomposition produces methane were not discarded, but recycled.

4      GWD-8-Q22*:

When storing Renaissance oil paintings, museums conform to standards that call for careful control of the surrounding temperature and humidity, with variations confined within narrow margins. Maintaining this environment is very costly, and recent research shows that even old oil paint is unaffected by wide fluctuations in temperature and humidity. Therefore, museums could relax their standards and save money without endangering their Renaissance oil paintings.

Which of the following is an assumption on which the argument depends?

A. Renaissance paintings were created in conditions involving far greater fluctuations in temperature and humidity than those permitted by current standards.

B. Under the current standards that museums use when storing Renaissance oil paintings, those paintings do not deteriorate at all.
         

C. Museum collections typically do not contain items that are more likely to be vulnerable to fluctuations in temperature and humidity than Renaissance oil paintings.

D. None of the materials in Renaissance oil paintings other than the paint are vulnerable enough to relatively wide fluctuations in temperature and humidity to cause damage to the paintings.

E. Most Renaissance oil paintings are stored in museums located in regions near the regions where the paintings were created.
