求助，这是一个附件中的题目以及解析。问题是为什么不能选E，E是说一个alternative方案的劣势啊，应该也可以吧

By competing with rodents for seeds, black ants help control rodent populations that pose a
public health risk. However, a very aggressive species of black ant, the Loma ant, which has
recently invaded a certain region, has a venomous sting that is often fatal to humans. Therefore,
the planned introduction into that region of ant flies, which prey on Loma ants, would benefit
public health, since____________ .


这是一个方案推理。这道题方案和目标都在结论中。

目标是：benefit public health 方案是：introduction into that region of ant flies

找选项：抓住方案，所提到的内容与评价方案有关。

(A) ant flies do not attack black ants other than Loma ants （提到了方案的否定性副作用。）

(B) Loma ants are less effective than many bird species in competing with rodents for seeds

(C) certain other species of black ants are more effective than Loma ants in competing with
rodents for seeds

(D) the sting of Loma ants can also be fatal to rodents

(E) some pesticides that could be used to control Loma ants are harmful to the environment

其他选项都不涉及方案和目标，不是方案推理的评估方向。不会是答案。
