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
