Business analyst: Urban sprawl has increasingly transformed rural farmland into suburbs in those parts of the country most vulnerable to winter storms. This explains why the sums paid out by insurance companies for storm damage have skyrocketed in recent years. If developers had not built homes in areas more frequently affected by violent weather, the costs of storm damage would not be as high as they are today.

Which of the following, if true, most seriously weakens the business analyst's argument?

A. Homes built in these new suburbs are widely spaced and are thus more vulnerable to storm damage than are urban homes.

B. Sums paid by insurance companies for storm damage in densely populated urban districts throughout the country have risen dramatically in recent years.

C. The rate of suburbanization of rural farmland has been highest in recent years.

D. Insurance companies demand higher premiums from homeowners in urban areas than from homeowners in rural areas.

E. On average, a tract of land in a city is of greater value than a tract of the same size in these new suburbs.

Landfills naturally release methane gas as the waste stored in them decays. Such decay is greatly accelerated by contact with rainwater. Some landfill operators use technology to extract methane before it escapes into the atmosphere, but this is an expensive process. A less expensive process, phytocapping, involves placing a layer of soil and dense vegetation on top of a landfill. This prevents most water from reaching the waste and could prevent the production and release of methane. Therefore, in order to reduce methane emissions in the most financially sound manner, landfill operators should adopt this alternative.

Which of the following would it be most useful to determine in order to evaluate the reasoning above?

A. Whether methane gas is produced by other human-influenced sources

B. Whether a combination of the methods would eliminate methane emissions

C. Whether other gases are released into the atmosphere as landfill waste decays

D. whether people consider current levels of landfill methane emissions to be harmful

E. Whether methane gas captured from landfills can be sold profitably as a fuel source

1、现象：理赔大幅上升，原因：在郊区这种易受影响的地区建了太多房子。
问weaken
思考：果因论证，考虑削弱他因削弱或同因反果、同果反因。

A：郊区建的房子比较widey spaced，所以比城市的房子更容易受影响。解释前提，加强。
B：城市地区因暴风破坏的理赔大幅上升。正确，他因削弱，理赔上升不是由于郊区，而是由于城市。
C：近年来郊区化最高。无关。
D：城市比乡村的保费高。无关。
E：城市比郊区地贵。无关。

选B

2、A方法：提取甲烷，但是操作很贵，B方法：覆盖土壤和植被，减少甲烷产生和释放，操作便宜。从经济角度上应该选B。
问evaluate
思考：对比型，有没有A和B在经济上额外的优缺点

A：甲烷是不是由其他来源产生的。无关。
B：是否A+B方法可以完全消除甲烷产生。A+B肯定比单独B更贵。
C：垃圾释放的是否有其他气体。无关。
D：人们是否认为现在释放甲烷的量是有害的。无关。
E：提取的甲烷是否可以当做燃料出售。正确，A方法在经济上额外的优点，如果可以出售，那可以减少A的成本。

选E

1. Weaken B
【P】U很多RF->S 在冬天风暴严重地区，所以保险公司的费用总额近几年上升
【C】如果不在频繁发生violent weather地方造房子，storm伤害就不会和现在一样高
A 解释了为什么S里的房子更容易遭到破坏 增强 不在这些地方建房子 花费就不会那么高了       
B 在U密集的街区 sum高 说明不是Suburbs产生的cost高 削弱了
C rate of suburbanization无关       
D 在U的保险费比R高 premiums和保险公司最终pay的钱 不是一样的 要看伤害多少 赔多少       
E 城市和新S的价值 。。。？无关比较
2. Evaluation B
【P1】W腐烂L释放M，+雨水腐烂速度会加快
【P2】有些技术，capture M，但很贵；P不贵，限制水从而减少M的释放
【C】为了减少M，要用P (alternative)
B 给出折中方案

1 因为把很多房子由农村迁往城市，这些城市应对冬季暴风能力较低，所以保险公司支付风暴破坏的支出近年上升。入宫不在这个区域建造房子，风暴的保险支出就不会像现在一样高
问 削弱
A 这边的房子比农村房子脆弱——增强
B 农村的风暴保险支出近年也大幅上涨
C 建房子在郊区的趋势最近很强烈——无关
D 保险公司对农村需要的保费高于郊区——无关
E城市和郊区比——完全不是题目的对象
==>B

2 用科技防止天然气泄露进空气，贵。便宜的方法是盖一层土，在上面种蔬菜。这种方法既可以组织水渗透，又可以组织天然气泄漏。因此，为了更加经济的防止泄露，应该用这个方法
问 evaluate——更加经济，考虑成本+收益
A 是否有其他人为影响的泄露方法——无关，有没有其他的泄露无关处理方法的经济性
B 两个方法结合是否会消除泄露——无关
C 如果landfill腐烂，是否有其他天然气泄露——无关，评估的就是这一种
D 现在的泄露水平是否有害——无关
E 提取的天然气是否能出售——正确，如果可以，科技方法收益提高，成本降低，可能不那么贵了
==>E
