试题详情
题目：
In Colorado subalpine meadows, nonnative dandelions co-occur with a native flower, the larkspur. Bumblebees visit both species, creating the potential for interactions between the two species with respect to pollination. In a recent study, researchers selected 16 plots containing both species; all dandelions were removed from eight plots; the remaining eight control plots were left undisturbed. The control plots yielded significantly more larkspur seeds than the dandelion-free plots, leading the researchers to conclude that the presence of dandelions facilitates pollination (and hence seed production) in the native species by attracting more pollinators to the mixed plots.
Which of the following, if true, most seriously undermines the researchers’ reasoning?
Which of the following, if true, most seriously undermines the researchers’ reasoning?
选项:
A、Bumblebees preferentially visit dandelions over larkspurs in mixed plots.
B、In mixed plots, pollinators can transfer pollen from one species to another to augment seed production.
C、If left unchecked, nonnative species like dandelions quickly crowd out native species.
D、Seed germination is a more reliable measure of a species’ fitness than seed production.
E、Soil disturbances can result in fewer blooms, and hence lower seed production.
答案:
E

王文静老师这道题a选项为什么不对呢？蜜蜂更喜欢d 所以更多去有d的花促进传粉导致seed产量增加 这样不可以是正确答案吗

提问：
老师我有点费解，这道题的逻辑链不是在说 dandelions的存在和attract more p的关系吗？那跟种子产量有什么关系？您可以帮我把做题的过程和所有选项都讲一下吗？

老师好 我想问下 B选项说“在mixed plots里，pollinator可以通过将pollen从一个种群传到另一个种群从而促进种子的生产” 这不是跟文中说“dandelion通过吸引更多的pollinators来促进种子的生产”这个推理 不同吗？那B不是也可以undermine原文的推理吗？

求解释C为什么错，网上的答案说C与原文事实不符合，那怎么判断什么是与原文事实不符，还是直接削弱呢？
