九山环一湖

1,Political Advertisement:

Mayor Delmont’s critics complain about the jobs that were lost in the city under Delmont’s leadership.  Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office.  So there can be no question that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger.

Which of the following, if true, most strengthens the argument in the advertisement?

1. The average pay for jobs created in the city during the past three years was higher than the average pay for jobs created in the city earlier in Mayor Delmont’s tenure.
   



2. Average pay in the city was at a ten-year low when Mayor Delmont took office.
   



3. Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again.
   



4. The average pay for jobs eliminated in the city during Mayor Delmont’s tenure has been roughly equal every year to the average pay for jobs citywide.


5. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city

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.

Q1: D.
D says Average pay for jobs losted = city-wide average pay, and theadvertisement states that average pay for new jobs > city-wideaverage, so D supports the argument that the average paycheck in this city has been getting steadily bigger.

Q2: D.
两害相权取其轻．Methane without burning contributes more to green house effects than Carbon dioxide generated by burning of Methane.

答案是C,C

Well, I guess the 答案错了．  I'm pretty confident of my answers, unless some NN could convince me otherwise :-)

Agree, the answer must be D, D        .\,

32 提我觉得应该是C。

    proposal 观点 ：M should be burned

    objection 观点： M burn 了危害更大，所以不能burn

   counter object  要说burn 了没有危害 ， 所以是D。

偶不是牛NN。M的危害比二氧化碳大，那么把M转换成二氧化碳危害相比要小，得到改进了

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

if it's D, then the global warming will be increased rather than reduced.  what you think?
