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?
什么叫“most undermines the defense of the government’s plan”?
如果原文讲The objection that the ban would reduce restaurants’ revenues is ill founded. 又说government’s plan使该地区的收入增加比其他地方快,那E的选项说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是不是相当于否定both objection and government’s plan?
