In two months, the legal minimum wage in the country of Kirlandia will increase from five Kirlandic dollars(KD5.00) Per hour to KD5.50 per hour. Opponents of this increase have argued that the resulting rise in wages will drive the inflation rate up. In fact its impact on wages will probably be negligible, since only a very small proportion of all Kirfandic workers are currently receiving less than KD5.50 per hour.
Which of the following, if true, most seriously weakens the argument?
Most people in kirlandia who are currently earning the minimum wage have been employed at their current jobs for less than a year.
Some firms in Kirlandia have paid workers considerably less than KD5.00 per hour, in violation of kirlandic employment regulations.
Many businesses hire trainees at or near the minimum wage but must reward trained workers by keeping their paylevels above the pay level of trainees.
The greatest growth in Kirlandia's economy in recent years has been in those sectors where workers earn wages that tend to be much higher than the minimum wage.
The current minimum wage is insufficient for a worker holding only one job to earn enough to support a family ,even when working full time at that job.
In fact its impact on wages will probably be negligible（adj. 可以忽略的）, since only a 【very small proportion】 of all Kirfandic workers are currently receiving less than KD5.50 per hour.
Kirlandia的最低工资即将从时薪5KD涨到时薪5.5KD，反对者认为会带来通货膨胀。但实际上目前工资在5.5KD以下的工人很少，调整最低工资带来的影响可以忽略不计。问weaken：
B选项：Some firms in Kirlandia have paid workers considerably less than KD5.00 per hour, in violation of kirlandic employment regulations.
提高最低工资，这些firms也可能继续违反规定，无法削弱
C选项：Many businesses hire trainees at or near the minimum wage but must reward trained workers by keeping their paylevels above the pay level of trainees.
很多trainee的工资是在最低工资附近的，但是trained workers的工资是要高于trainee的，所以一旦trainee的工资涨了，那trained worker的工资肯定也要涨，所以很多工人的工资都要涨。
题干说的是 only a very small proportion会有影响，显然C选项表明会有很多工人受到影响，有效weaken [a small proportion]
思路总结：看到only a very small proportion，问削弱，CQ方向可能是不止a small proportion会受影响，而是会影响large proportion
