“The Cumquat Café began advertising on our local radio station this year and was delighted to see its business
increase by 10 percent over last year’s totals. Their success shows you how you can use radio advertising to make
your business more profitable.”
The argument states that cumquat cafe was able to increase its business by advertising in the local radio station.stated this way , the argument is based on questionable assumptions.The argument fails to provide clear evidences and supporting facts to substantiate the claim .Hence the argument is unconvincing and deeply flawed.
Firstly, the argument mentions that the cafe started advertising in the local radio station , leading to increase in its business.The argument is making an assumption that radio is popular amongst the locals and that people do listen to radio.more over the argument also assumes that people make purchase decisions based on advertisement in radio.This is not substantiated by any data.It is also possible that the cafe is frequented motly by the teens and that teens do not tune into radio at all.In such a case the Argument will be considerably weakened.Hence , we need proper evidence to substantiate the claim laid in the argument.
Secondly the argument states that the advertisement in radio lead to a 10 percent increase in the business.We have been provided no evidences on the same.It is possible that the business normally experiences a growth of 10 percent year on year and that advertisement in radio has not affected the revenue in any way.We also dont know what other modes of advertising has been undertaken by the cafe .If there are more than one medium in which the cafe has started to advertise such as news paper, ads in local entertainment channels, then it will not be possible to ascertain the entire increase in revenue to radio.Hence the argument would have been strengthened if more data would have been provided to prevent the alternate reasoning.
Finally the arguments is making a recommendation on using the radio advertising to make busineess protitable.This is indeed a very general claim and the argument fails to take the cost benefit analysis into consideration.We do not know how much advertising cost in the radio and t he corresponding increase in revenue its likely to bring.without such a analysis busineesses may actually make a loss.hence the argument will fall apart.
The argument is flawed and based on questionable assumptions and could have been further strengthened if evidences would have been given to substantiate the claims.
First up, there were a few errors in spelling that could have been avoided, as well as commas that were spaced wrong and fullstops, with no gap and no capital letter in the beginning of the sentence (see underlined in above quotation). Also evidence is a singular plural, there is no such thing as evidences.
Based on a brief reading, I would probably give this a 3. I think your points slightly miss the point of the text. I believe, based on the sentence given there were two major issues with the statement.
Firstly, there is no evidence given that the increase in profits were the result of radio advertising, the results could have been due to a strong economy, or a season of excellent weather which encouraged people to go to cafes.
Secondly, the claim that radio advertising can bring success to "your business" makes the assumption that radio advertising is equally useful for all types of business, which is a completely unsupported and generalised argument.
