Brochure: Help conserve our city’s water supply. By converting the landscaping in your yard to a water-conserving landscape, you can greatly reduce your outdoor water use. A water-conserving landscape is natural and attractive, and it also saves you money.
Criticism: For most people with yards, the savings from converting to a water-conserving landscape cannot justify the expense of new landscaping, since typically the conversion would save less than twenty dollars on a homeowner’s yearly water bills.
Which of the following, if true, provides the best basis for a rebuttal of the criticism?
A. Even homeowners whose yards do not have water-conserving landscapes can conserve water by installing water-saving devices in their homes.
B. A conventional landscape generally requires a much greater expenditure on fertilizer and herbicide than does a water-conserving landscape.
C. A significant proportion of the residents of the city live in buildings that do not have yards.
D. It costs no more to put in water-conserving landscaping than it does to put in conventional landscaping.
E. Some homeowners use more water to maintain their yards than they use for all other purposes combined. 作者: prayer 时间: 2010-1-12 11:03
我认为答案是B，因为文章中讨论的是新的节水装置是否省钱的问题，那个反对意见说新的装置剩下的钱没有安装费用多，这东东省不到20块钱一年。讨论的是省钱还是花钱，主要是跟安装这个新的装置之前情况比较。B符合，以前的装置还需要一堆东西，更花钱。 D：安装费上新的和传统的差不多，但是更换成新的装置还是需要额外的费用，这笔费用比节省下来的水钱多多了，这里也没用。 Ether purpose属于无关词作者: herosweet 时间: 2010-1-12 11:18
