The arguer drew out the conclusion that it is profitable to build up a jazz music club in the city of Monroe. To support the statement, the argument cites the following facts: the nearest jazz club is 65 miles away which allows the new music club to occupy the entire market; jazz is highly popular in Monroe because there are over 100,000 people attending jazz festival last summer, there are certain famous jazz musicians living in the Monroe, and ' Jazz Nightly ' is the highest- rated radio program in Monroe; a nationwide survey shows that the typical jazz fans tend to spend around 1,000 dollars yearly on jazz entertainment.
First, it is possible that local people don't think 65 miles is too far due to the exist of cars and those who really enjoy jazz only go to the music club they like, ignoring the new music club. Second, the argument doesn't tell us the number of local citizens, so perhaps 100,000 people are the little part of all. Plus, though there are some well-known jazz musicians in the Monroe, we don't know if they travel to the city by chance. Besides, the author ignores the possibility that there are few radio programs in that city, which makes them have to choose a program, even though all radio programs are boring. Third, the passage doesn't show the reliability of the survey and possibly the survey was made by some unskilled persons. Under either scenario, adopting the author's proposal might harm, rather than benefit.
