This argument concludes that people complain the increased time of national news in late-night news program by replacing the weather and local news, as an result, and that increasing number of local businesses cut off their advertising contracts with the station. therefore, the business manager who writes this memorandum recommends the station should restore the time devoted to weather and local news to its original level. Nevertheless, the manager fails to provide the sufficient evidences to permit a proper evaluation of the argument's reasoning.
One of the memorandum's deficiencies involves the exact number of the complaints received. The manager didn't provide the accurate percent of the feedback from the viewers, instead, he or she just says "most of the complaints". to some extent, more than 50 percent can be defined to be "most", thus, it would not be obvious to note that reduced time of weather and local news are the major issue what people are concerned with if only half of audiences complain. Additionally, there is no specific evidences to elaborate that the complaints are about the limit time of the types of news. For example, the complaints are possible about the validity of the weather and local news. In any event, more information about the exact number of the feedback from the viewers and the specific context of complaints are needed in order to determine whether the reduced time and the complaints as presented have a necessary correlation.
Another weakness of the memorandum is that it provide no information about the connection between the cancelation of ads contracts and the change time of news of this station. It would be useful to work out the true reason why local businesses choose to end the cooperation with the station. For instance, the station maybe lose their ads contracts because the late-night programs become less fun and organized, what's more, it is reasonable to blame the deficient display of local businesses. To kown clearly the reason why businesses bring down the ads, it would be helpful to show some representative information about the sincere opinion of businesses.
Yet another of the editorial's shortcomings has to come with whether the station could regain the attraction of viewers and avoid losing the income of further advertising if we restore the time devoted to weather and local news. There are some other solutions to resolve the problems. For example, the station can enhance the quality of the late-night news programs. It would require more detailed information support the viewpoint of the manager.
In the view above, only the manager can explain the deficient statements as presented above, would it be persuasive to conceive the station change its time schedule of late-night news programs.
