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?
分析A选项
分析B选项
分析C选项
分析D选项
分析E选项

当前版本由 不灭的凤凰 更新于2018-10-25 21:32:14 感谢由 不灭的凤凰 对此题目的解答所做出的贡献。此题主要有两个点：
1.问题陷阱：rebuttal是问对“water－conserve land不省钱“的反驳，也就是答案要支持这个新方案是省钱的。
2.根据cost就可以锁定答案在BD。
B 正确，反驳因为老款的涉及到肥料除草剂这些会更多cost，正好驳斥掉观点。
D 比的cost不是put in，而是conversion，排除。
P：水景观节约水费少
C：水景观不能节约开支
偷换概念：水费=开支
削弱方向：添加其它不属于水费的开支
B选项：节约肥料
符合削弱方向

因为第一个人的观点是，有水的这个景观会比传统景观更省钱，第二个人认为并没有。题目要求反驳第二个人。所以就要说明传统景观和有水景观的expense区别在哪里？简言之就是哪个日常投入少哪个日常投入贵，B回答了这个问题。
