范文224中AA第三篇弱弱求教

骡子桑

各位NN，
在看范文有些问题弱弱求教一下
曼哈顿FoV笔记中说到，我们不能有任何外界的知识带入到argument里去。
但是以下范文中作者却阐述了“投电视广告会影响人们的行为”这样的常识，请问作者给出这一段的态度究竟在此处是认可原文的观点，将这句话认为一句常识，所以不需要额外证明吗？

感觉与FoV中的攻击观点有所出入。
是否我们在写AA的时候，允许某些常识，比如天空是蓝的，地球是圆的，还是“投电视广告会影响人们的行为” 算一种常识？

原题：
3. The following appeared in a memorandum issued by a large city’s council on the arts.
“In a recent citywide poll, fifteen percent more residents said that they watch television programs about the visual arts than was the case in a poll conducted five years ago. During these past five years, the number of people visiting our city’s art museums has increased by a similar percentage. Since the corporate funding that supports public television, where most of the visual arts programs appear, is now being threatened with severe cuts, we can expect that attendance at our city’s art museums will also start to decrease. Thus some of the city’s funds for supporting the arts should be reallocated to public television.”

To be fair, however, we must recognize that the author’s assumption is a special case of a more general one that television viewing affects people’s attitudes and behavior. Common sense and observation tell me that this is indeed the case. After all, advertisers spend billions of dollars on television ad time because they trust this assumption as well.
