By competing with rodents for seeds, black ants help control rodent populations that pose a public health risk. However, a very aggressive species of blank 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.
Which of the following, if true, most strengthens the argument?
分析A选项
分析B选项
分析C选项
分析D选项
分析E选项

原文主要两个意思：
blank ant可以控制其他rodents(危害人类健康）;
引进ant flies去捕食Loma ants（一种对人类是致命的blank ant）
A选项正确，说明蚁蝇会减少L蚂蚁数量，降低健康风险
B选项和C选项 无关
D选项 L对于其他rodent也是致命的，无关
E选项提出另外一种控制L蚂蚁的方式，偏离讨论对象

对于E选项的补充，个人同意官方OG的解析，E选项不是完全无关，只是对于原文结论的论证能够提供的支持作用很小，A项建立起了ant flies与目标达成的联系，已经是最佳选项，相比之下，E项完全没有提到ant flies 作用很小
