单选题 Experienced gardeners advise against planting snap peas after late April because peas do not develop properly in warm weather. This year, however, the weather was unusually cool into late June, and therefore the fact that these snap peas were planted in mid-May is unlikely to result in crop failure despite the experts' warnings.
The pattern of reasoning displayed above is most closely paralleled in which one of the following?

A、 According to many gardening authorities, tomatoes should not be planted near dill because doing so is likely to affect their taste adversely; however, since these tomatoes were grown near dill and taste fine, there is clearly no reason to pay much attention to the so-called experts' advice.
B、 Since African violets do not thrive in direct sunlight, it is said that in this region these plants should be placed in windows facing north rather than south; however, since these south-facing windows are well shaded by evergreen trees, the African violets placed in them are likely to grow satisfactorily.
C、 Where flowers are to be planted under shade trees, gardening expertsoften advise using impatiens since impatiens does well in conditions of shade; however, it is unlikely to do well under maple tree since maple tree roots are so near the surface that they absorb all available moisture.
D、 Most seeds tend to germinate at much higher rates when planted in warm soil than when planted in cold soil; spinach seeds, however are unlikely to germinate properly if the soil is too warm, and therefore experts advise that spinach should be planted earlier than most vegetables.
E、 (E) House plants generally grow best in pots slightly larger than their existing root systems, so the usual advice is to repot when roots first reach the sides of the pot; this rule should not be followed with amaryllis plants, however, because they are likely to do best with tightly compressed roots.

【正确答案】 B

【答案解析】[解析] 本题段落中的论证是通过分析一件事情在不同条件下具有不同的结果的差异原因，然而把差异原因消除，从而得到了一件事情在不同的条件下仍有可能达到一致的结果。(B)通过消除南部窗台上的阳光，从而得出了不能在阳光下茂盛生长的非洲紫罗兰在南部窗台上也能很好地生长的结论，该结论的推理模式显然与题干中的推理模式相一致。因此(B)为正确选项。(A)、(C)、(D)和(E)四个论证中都没有用到消除差异原因的方法，因此均为错误选项。
