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. ----------------------------------------------------------------- 解答是B 但是我不懂為什Critism以B為基礎如果是這樣 conventional landscape會花很多錢那轉成WATER的不是應該更省錢請各位大大幫忙解惑感謝我這題快搞兩小時了QQ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.116.171.191
