这道题首先选项的意思就很费解！！！

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?这句话看不懂
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.

这题到底是让反对criticizm还是支持criticizm呢？
然后答案为什么是B呢？？  哪位高手指点一下？？

rebuttal: criticize, point out shortcoming of another proposal, present counter evidence.  In short, AGAINST the criticism.

B attacks the criticism by adding more reasons for choosing water-conserving landscapes over conventional one.

D选项说安装water-conserving landscaping 的花费不比安装 conventional landscaping的花费多，岂不是也反驳了题干中的criticism么

我觉得D的话 不管是不是cost no more, 要改成新的地形就必须有new expense，是要justify这笔费用的必要性

现在思考的是在已经装了conventional landscaping的情况下是否改造成water-conserving landscaping划算，而不是什么都没有的情况下比较装哪种划算
