¡¡¡¡(Ñù±¾²»¾ß±¸´ú±íÐÔ)¸Ä´íÄ£°å£º(1) One problem with the argument involves the cited statistics about sales of books and magazines. It is unreasonable to draw any conclusions about their sales in the future based on statistics regarding last year¡¯s. Depending on the total number of books and magazines, it is entirely possible that those on personal health are not representative of the whole. For example, perhaps the sales regarding sports totaled more than $50 billion. If so, then the arguer¡¯s recommendation might amount to poor advice for us.

¡¡¡¡(ÊÕ¼¯Êý¾Ý¹ý³ÌÓÐÎó)¸Ä´íÄ£°å£º(2)The survey methodology might be problematic in two aspects. First, we are not informed whether the survey required that respondents choose their concern between alternatives. If it did, then the results might distort the preferences of respondents, who might very well prefer a certain one not provided in the survey. Secondly, we are not informed whether survey responses were anonymous, or even confidential. If they were not, the respondents might have provided responses that they believed those in power would approve of, regardless of whether the responses were truthful. In either event, the survey results would be unreliable for the purpose of drawing any conclusions about people¡¯s real increasing inclination.
