However, the supplement will not raise any worker’s income above what government assistance would provide if he or she were not gainfully employed.这句话的意思，也就是说政府会给那些工作了的，但是收入还没有不工作领政府补贴的人多的人补贴是吧？~~政府给补贴，本来是想让雇主hire 员工更便宜，这样薪水就平衡了~~但是也最多就达到没工作的人的补助水平了~~于是就不会给不工作的人一个financial incentive~~~（是不？）如果我理解正确的话要谢谢大牛你啊！！如果理解不正确请指正哦~
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?
A.Ant flies do not attack black ants other than Loma ants 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.The use of pesticides to control Loma ants could have harmful effects on the environment. Answer: A
我觉得答案A没有错哈~ GMAT的CR，要关注结论（bible中有讲述的）：（1）结论中阐述的是引入“ant flies” 去eat L，从而benefit public benefit。选项A直接阐述“ant flies”的引入，对其他可以控制啮齿类动物增长的黑蚁没有attack。其实就是否认了ant flies引入的潜在危害，从而支持了原文结论。A是很直接支持结论的哈。（2）B中，承认其实深究的话，是有限支持。题中主要说的是L袭击人类啊，所以引入ant flies，B中米有结论的stimulus啊。 换个角度看哈，其实要是选择B的话，C基本上就是B的另一种表达方式，二者是一个意思啊，如果按亲的想法，亲选B的话，也阔以选C的。 直接分析一下其他选项，C和B一样啊，脱离了结论关键stimulus哈，多少不符题意。排除。 D weaken 。 E其实也是支持，但是相对A来说，不素那么直接的支持，也是脱离了结论的stimulus了。
我再来补充下第一题吧~ 个人理解题目中这句是解题关键“However, the supplement will not raise any worker’s income above what government assistance would provide if he or she were not gainfully employed.”尤其是“if he or she were not gainfully employed”.
