Editor: Articles in Gardening Magazine often spur sales of the plants they
describe, particularly among people new to gardening. Accordingly, we will
no longer publish articles or accept advertisements praising the beauty of
rare wildflowers. Most such plants sold to gardeners have been difficult to
propagate under cultivation, so plant sellers often collect them in the wild. Our new policy is part of our efforts to halt this yearly plundering of our native plant populations.
Which of the following, if true, casts the most doubt on the wisdom of the
magazine's new policy as a way of pursuing the intended effect?
A. When people new to gardening buy plants, they often fail to take adequate
care of the plants that they buy and become discouraged from buying those
varieties again.
B. Plant sellers who sell rare wildflowers have no reasonably inexpensive
alternative way to offer their wares directly to new gardeners.
C. The demand for rare wildflowers rarely exceeds the number of such plants
that can be collected in the wild by plant sellers.
D. The propagation of rare wildflowers often depends on the plants' interaction
with other organisms in their environment, such as plants that create suitable
soil conditions or insects and birds that disperse seeds.
E. Revenues from sales of plants collected in the wild are supporting the
discovery of new low-cost techniques enabling rare wildflowers to be readily
propagated in nurseries.
我一直在D和E之間徘徊～答案是E。但我覺得D也很像可以weaken他
該怎麼判斷呢？請大家指點迷津!!
