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?
【选项】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.
