The following appeared in a memorandum from the manager of WWAC radio station.
"WWAC must change from its current rock-music format because the number of listeners has been declining, even though the population in our listening area has been growing. The population growth has resulted mainly from people moving to our area after their retirement, and we must make listeners of these new residents. But they seem to have limited interest in music: several local stores selling recorded music have recently closed. Therefore, just changing to another kind of music is not going to increase our audience. Instead, we should adopt a news-and-talk format, a form of radio that is increasingly popular in our area."
Write a response in which you discuss what questions would need to be answered in order to decide whether the recommendation and the argument on which it is based are reasonable. Be sure to explain how the answers to these questions would help to evaluate the recommendation.
我们发现brief passage中，有多处不是事实（而是作者的推论）的地方： * “WWAC must change from its current rock-music format” * “they seem to have limited interest in music” * “just changing to another kind of music is not going to increase our audience” * “we should adopt a news-and-talk format” 这些地方就出现了从事实到推论的逻辑过程值得我们分析。 我仅以材料文中的一个部分为例： 针对推论“they seem to have limited interest in music”的依据“several local stores selling recorded music have recently closed”中出现了如下数个常见的逻辑疑点： 地点问题：local 思考： Those retirees who have moved to this area may purchase music from sources other than those local stores. 依据指令答题： Are there sources other than those local stores from which those retirees purchase music? ← 提出question。 If there are those sources, such as the Internet or stores from other areas, ←（用对原文逻辑不利的答案）回答question。 the alleged limited interest is not the actual case, and instead, the actual case may be that it is not from the local stores that those retirees just purchase music. ← 指出在这个答案的情况下原文的逻辑被削弱了。 它因问题：several stores have recently closed 思考： Those that have recently closed may be closed for various other reasons, such as a limited range of choice, overpricing, or the saturated local market in which the intense competition eliminates some of the music stores, instead of listeners’ limited interest in music. 依据指令答题： Are there various other reasons for which those stores have recently closed?← 提出question。 As a matter of fact, there may be. For example, it is likely that those stores have a limited range of choice that cannot meet the needs of those retirees as music listeners or their music does not suit the taste of those listeners. If those sell music at high prices, overpricing may therefore be another possible factor. In addition, the local music market may have intense competition that eliminates those music stores that have recently closed, or it is likely that a saturated local market renders those less competitive stores redundant and has forced them to be out of business. ←（用对原文逻辑不利的答案）回答question，同时，可能举例。Any of the above likely situation would contradict the alleged conclusion that those retirees have limited interest in music. ← 指出在这个答案的情况下原文的逻辑被削弱了。 范畴问题：recorded music 和 偷换概念：selling 依据指令答题： Is it only the recorded music that those retirees do not like? Since there are other types of music, those retired people may enjoy live music instead of music recorded in CDs. At this point, it is also necessary to consider whether or not they simply do not like music they need to pay for. ← 提出question的时候，不是只有问句形式，而也可能用陈述句句型。 Since there is free music in pubs, bars or the street, or on the radio, they do not necessarily need to spend money on music. In either case, the author’s assertion is overgeneralized since those retirees may just have limited interest in recorded music as one type of music rather than music in general / overall.
