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
