这道题应该选C吧。 实际上题目是说年龄在20多岁这一阶段的人很少读报,在30 岁以上的读报很多。 二十多岁的人在人口中虽然占较大比例但是报纸发行者却不担心十年后报纸销量会减少。 这里就有一个推理的gap。 二十年以后这些20岁的年轻人就会步入30岁阶段,如果他们读报比例仍然10% ,而不是50%,那么报纸销量肯定会减少。 可是,这个报纸发行者的自信哪里来呢? 真正的原因就在于 人们的偏好问题,20多岁时不爱看报,以后30多岁爱看了。也就是。The proportion of Domoricans in their twenties who regularly read a newspaper has always been low. ABDE 任何选项的讨论实际上都解决不了问题,从某种程度上来说他们都是无关的。 希望你在做题中仔细体会这种每道题推理中的gap所在,和无关选项的迅速排出。 这在考场上帮助很大。 加油吧!
