Surveys in Domorica indicate that only 10 percent of Domoricans in their twenties read a newspaper regularly, while more than half of all Domoricans over thirty read a newspaper regularly. Although Domoricans in their twenties constitute a large proportion of the population, newspaper publishers nonetheless predict that ten years from now, the percentage of Domoricans who regularly read a newspaper will probably be no lower than it is today.
Which of the following, if true, provides the strongest grounds for the newspaper publishers' prediction?
The number of Domoricans in their twenties is less than the number of Domoricans over thirty.
The number of newspapers in Domorica has been gradually increasing over the past several decades.
The proportion of Domoricans in their twenties who regularly read a newspaper has always been low.
The surveys defined a regular reader of a newspaper as someone who reads a newspaper more than twice a week.
The proportion of Domoricans who regularly read a newspaper was higher 20 years ago than it is today.
此题破题点关键在于结论句的 ten years from now, 说明十年后的情况和现在基本没有变化，这就要说明P里陈述的读书情况是一个普适性trend
C. has always been low就说明了该情况可以一直延续下去
A. 两个年龄阶段的人数对本题没有影响，要关注的是各个年龄阶段的人 读书比例 是否有变化
