**The following appeared in a memorandum from the manager of WWAC radio station. "To reverse a decline in listener numbers, our owners have decided that WWAC must change from its current rock-music format. The decline has occurred despite population growth in our listening area, but that growth has resulted mainly from people moving here after their retirement. We must make listeners of these new residents. We could switch to a music format tailored to their tastes, but a continuing decline in local sales of recorded music suggests limited interest in music. Instead we should change to a news and talk format, a form of radio that is increasingly popular in our area."**  
  
Answer:  
  
The argument suggests the equivocal nature of the manager of WWAC radio station. It can be inferred from the argument that the management is taking decisions hastily without much survey or knowledge about their listeners. It can be clearly seen from the lines "We could switch to a music format tailored to their tastes, but a continuing decline in local sales of recorded music suggest limited interest in music. Instead we should change to a news and talk format", it can be clearly seen that the management is not sure about what their current listeners like. There is clearly no proof in the argument about what their current listeners like to listen.  
  
Secondly, how can one conclude that because of the decline in the sales of the local record music suggest that limited interest of people in music? It is possible that people might not be buying local recorded music because the music quality is not good or there might be a case that the economy is not good and people might not prefer to spend money on recorded music. How can the radio station switch to a music forma inclined to the taste of the people when they are not sure what people like to listen to? There is no proof of a survey being conducted which tells what people of the area like to listen to.  
  
Thirdly, there is a claim which says "the decline has occurred despite the population growth in the listening area". It might seem plausible at first that there is a decline in the number of listeners to a radio station in spite of an increase in the population in the area, but it is false. How can we connect the increase in the population in the area with the number of users who listen to a radio station? Further, there is no proof that the increasing population likes to listen to radio or not.  
  
It might seem that there is a connection between the decrease in the number of rock-music and when argument suggests that "the growth has resulted mainly from people moving here after their retirement" ie. increase in the population of the elderly people but, what the argument fails is that it never tells whether the increasing population likes rock music or not? There is no proof in the argument that the eldery people don't like rock music.  
  
In summation, the argument seems reasonable in some areas, but it doesn't provide us with the solid proof which makes it less acceptable. The argument is suggest that the manager is obscure about his current listeners tastes and is taking decisions in wrong direction.
