In the second place , the comparison in this argument is incomplete and selective, the arguer discovers that using fans alone is more cost effective than using air conditions alone, and that using both fans and air conditioners are the least expensive way of cooling. However, the arguer fails to provide any information regarding the actual amount of time for using, respectively, fans alone, air conditioners alone, and both fans and air conditioners in those three groups of surveyed families. It is very likely that these three groups of families are located in three very different climatic regions of Claria, and hence the amount of days of the year during which they need to cool their houses varies significantly. Families living in cooler areas of the nation certainly cool their houses for fewer hours and hence use less electricity than families living in hot areas, no matter what cooling appliance they use. Unless we are certain that the surveyed families ling in the same climatic region, or that they need to cool their houses for the same amount of hours in the same year although they live in different regions, which is very unlikely, we have every reason to doubt the trustworthiness of this comparative study. Furthermore on electricity may be using more electricity for purposes other than cooling. Unless the arguer also takes this factor into consideration, the comparison is unconvincing.

　　First of all, the argument is based on a hasty generalization. According to the cited studies, professors at Bronston College are happier living in small towns when their spouses are also employed in the local area than when their spouses work in distant areas, which is understandable. This fact tells very little about what actual conditions the professors often consider as important when they choose where to work. Even if we accept the arguer’s assumption that whether their spouse can find a job in the local area Is the only important question that new professors consider when they decide whether to accept is it likely that the professor will consider accepting the university’s offer. Consequently, it is unwarranted to assume that new professors will accept Pierce’s offer whether their spouse can find satisfactory employment in the local area.

　　In addition, the arguer fails to consider several other relevant factors that may influence professors’ decision. For instance, since Pierce’s location is not ideal, the pay it offers should be high enough to be attractive. New gifted professors are also concerned about the position they can have and the courses they supposed to teach in the new university. What’s more, what researchers care most about might be the university’s research conditions such as laboratory equipments, adequate research funds, etc.

　　Finally, the arguer hints that the morale of Pierce’s entire staff is low, but he fails to analyze the causes. Is it because the management of the university is poor, or because the pay is too low, or because the local area stuffers from economic depression, or because the local environment is severely damaged by industrial pollution? Under these circumstances, offering employment to the spouse would be ineffective at all for the purpose of attracting more new professors. Furthermore, if these problems do exist, even if Pierce succeeds in hiring many of the most gifted teachers and researchers of the country, the general moral of the whole faculty would remain low.

　　The major problem with this argument is that the arguer fails to convince us that Cedar’s present supplier the Good-Taste should be fired. First, the fact that the Good-Taste is the second most expensive caterer in the city may be due to its better foods, quality service and high reputation in this industry. Second, the fact that it prices have been rising for the last three years may be due to nationwide inflation or the rising cost in the food industry. Third, the fact that Good- Taste refuses to serve special diets does not indicate that it cannot meet the needs of Cedar Corporation unless the arguer can demonstrate that Good-Taste served special diets at first and now it refuses to do so hence disappointing Cedar’s employees complained, which makes it impossible for us to e valuate the overall service of Good-Taste. Maybe these three people are those few on special diets. Even if they have every reason to complain about the foods or service of the supplier on a certain day, these three people’s opinion lacks the necessary representativeness based on which we can make any general judgment concerning the overall performance of Good-Taste.
