标题: GWD 逻辑一题求助！！！感谢感谢！！！
Brochure:  Help conserve our city’s water supply.  By converting the landscaping in your yard toa water-conserving landscape, you can greatly reduce your outdoor water use.  A water-conserving landscape is natural andattractive, and it also saves you money.
Criticism:  For most people with yards, the savings fromconverting to a water-conserving landscape cannot justify the expense of newlandscaping, since typically the conversion would save less than twenty dollarson a homeowner’s yearly water bills.
Whichof the following, if true, provides the best basis for a rebuttal of thecriticism? （是削弱criticism的说法，还是问criticism怎么削弱brochure的？）
  1. Even     homeowners whose yards do not have water-conserving landscapes can     conserve water by installing water-saving devices in their homes.
  • A     conventional landscape generally requires a much greater expenditure on     fertilizer and herbicide than does a water-conserving landscape.
  • A     significant proportion of the residents of the city live in buildings that     do not have yards.
  • It     costs no more to put in water-conserving landscaping than it does to put     in conventional landscaping.
  • Some     homeowners use more water to maintain their yards than they use for all     other purposes combined.
    答案说是B，这题是怎么个逻辑啊？


    哎，做GWD好慌啊，思维越加混乱，信心越加被打击。还有10来天考试，紧张哇！！！怎么办呐？


    十分感谢！！

    Brochure的观点：省钱；
    Criticism的观点：不能省钱；
    问：哪一个最能削弱Criticism的观点，所以选项中能够证明新的water-conserving landscape的确能省钱就可以了，
    只有B能推出：B的意思说：传统的设施在灌溉和除草方面要花费更多的钱（所以换了新的设施自然在这部分把钱省下来了）

    迟了一点，我也说说自己的理解吧。
    Brochure是让大家装节水的，不但节水还能省水钱
    Criticism是说装新的花的钱比节约的水钱多多了；
    问的是那个能够反驳Criticism的观点。
    B说的是新的不但节水，还能节约用在肥料和杀虫剂上的钱。是划算的。
    其他的选项都不能反映出新的设备能省钱这点。
