Vorland's government is planning a nationwide ban on smoking in restaurants. The objection that the ban would reduce restaurants' revenues is ill founded. Several towns in Vorland enacted restaurant smoking restrictions five years ago. Since then, the amount the government collects in restaurant meal taxes in those towns has increased 34 percent, on average, but only 26 percent elsewhere in Vorland. The amount collected in restaurant meal taxes closely reflects restaurants' revenues.
Which of the following, if true, most undermines the defense of the government's plan?
When the state first imposed a restaurant meal tax, opponents predicted that restaurants' revenues would decline as a result, a prediction that proved to be correct in the short term.
The tax on meals in restaurants is higher than the tax on many other goods and services.
Over the last five years, smoking has steadily declined throughout Vorland.
In many of the towns that restrict smoking in restaurants, restaurants can maintain separate dining areas where smoking is permitted.
Over the last five years, government revenues from sales taxes have grown no faster in the towns with restaurant smoking restrictions than in the towns that have no such restrictions.
枚举推理
前提:V的几个城镇在限制在餐厅吸烟后仍然税收增加
结论:全国禁止在餐厅吸烟也不会影响税收收入
枚举了v的几个城镇作为样本,推出全国的结论,属于枚举推理
枚举的推理的方向:样本的代表性,是否有另外一个反样本
D,在那些限制吸烟的城镇的餐厅里是有吸烟区的,没有完全禁止吸烟,所以样本不能代表禁止吸烟后的全国的情况,削弱了推论
赞!
