The memorandum only plays a proper role in a general introduction, but it is not dependable, logical and persuasive enough because the lack of evidence and background details.The several factors cited by the writer are not reliable enough to be the base of the finding, a need of shifting programming. So I hold that it should be modified in the ways below.

The first factor has problems. The fact of the increased older listener and the decreased total ones does not have a provided background to make it trustworthy. Even if this fact is true, it still cannot lead to a necessity of such a shift, because older people may want to listen to more rock-and-roll music than a continuous news. And even if it is proved that they want to listen to such news, there is no evidence or estimation to show a rising number of older listeners or a declining number of total listeners in the future.

The second factor also has problems. The decreased sales of recorded music might not be caused by the rock-and-roll music programming, as the author does not provide any evidence or logical reasoning here to affirm it. It is highly possible that the decreased sales are caused by other affairs such as unemployment. After the programming is shifted, the sales may turn no better or even worse.

The last one has some problems, again. The neighboring cities' success has no evidence provided here to back it up. Even if they achieve some success, it might be a very small one that is ignorable. Even if they really achieve great success, it is still possible that it is not caused by the continuous news, nevertheless it is programmed. Even if it is caused directly by the continuous news, what happened in the neighboring cities might not happen here. So, it so assertive and insensible to put this fact here. Moreover, the background of that survey is not provided to make it trusty.

In all, this memorandum does not do well in providing necessary evidence or logically reasoning to make it trusty and persuasive. After being changed in the ways above, it will be a better argument.
