Day 109 Several factors indicate that radio station KNOW should shift its programming from rock-and-roll music to a continuous news format
The following appeared in a memorandum from the general manager of KNOW radio station.
“Several factors indicate that radio station KNOW should shift its programming from rock-and-roll music to a continuous news format. Consider, for example, that the number of people in our listening area over fifty years of age has increased dramatically, while our total number of listeners has declined. Also, music stores in our area report decreased sales of recorded music. Finally, continuous news stations in neighboring cities have been very successful. The switch from rock-and-roll music to 24-hour news will attract older listeners and secure KNOW radio's future.”
Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.
五问：
（1）“the number of people in our listening area over fifty years of age has increased dramatically, while our total number of listeners has declined. Also, music stores in our area report decreased sales of recorded music. Finally, continuous news stations in neighboring cities have been very successful”是事实，“Several factors indicate that radio station KNOW should shift its programming from rock-and-roll music to a continuous news format”是结论，值得反驳吗？（注意 KNOW要大写，是一个 radio station的名字。）
（2）本地区年龄在 50岁以上的人口增长的同时， radio station的听众减少，一定是因为摇滚乐节目造成的吗？是否可能有其他更重要的原因？例如：电台的广告太多， DJ水平太差等。
（3）本地的音乐商店所出售的音乐唱片的数目减少，一定是因为人们不愿意听音乐了吗？是否可能有其他原因？比如人们使用更先进的 itunes来下载音乐。即便人们不愿意购买音乐唱片，是否就意味着他们不愿意通过广播电台来收听免费的音乐？原文中是否给出了足够的信息来证明人们将会更喜欢听新闻而不是免费的音乐？音像店和电台不一样，一个花钱买唱片，一个免费听歌曲。商店销售量下降可能与经济萧条、购买力下降以及最近没有什么新唱片发行有关，而这种情况可能正好会使听电台音乐的人数有所增加。
（4）临近的城市与本地是否可能有所不同？原文中是否给出了足够的信息来说明临近的城市与本地之间的差异？哪些城市之间的差异可能导致在“临近的城市”能够取得成功的电台节目可能在本地并不成功？可能临近的城市最近正在做选举前的民意调查，所以当地居民对政治新闻更有兴趣。
（5）原文中是否给出了足够的信息来证明，年长的听众更容易被新闻而不是音乐所吸引？另外，年长的听众一定是我们的目标听众吗？而对于老年人来说，他们也许不爱听摇滚乐，但也没有证据说他们一定会喜欢政治新闻。
