39、The following appeared in an Avia Airlines departmental memorandum.

“On average, 9 out of every 1,000 passengers who traveled on Avia Airlines last year filed a complaint about our baggage-handling procedures. This means that although some 1 percent of our passengers were unhappy with those procedures, the overwhelming majority were quite satisfied with them; thus it would appear that a review of the procedures is not important to our goal of maintaining or increasing the number of Avia’s passengers.”

The recommendation endorsed in the argument is that a review of baggage-handling procedures is not necessary to maintain or increase the number of AVIA’s passengers .The authors cites the fact that only 1 percent passengers who traveled on Avia Airlines last year filed a complaint about our baggage-handling procedures as grounds for the conclusion. Moreover, the author reasons that the overwhelming majority were quite satisfied with those procedures. The argument involves the sort of gratuitous assumption and unreliable statistics, for this reason it is unconvincing.

The argument is based on the assumption that since only 1 percent passengers filed a complaint for baggage-handling procedures, the remaining 99 percent passengers must be satisfied with the issue. It is, however, not necessarily the case. Nor does the author cite any evident to support this assumption. The author fails to take into account other factors that might lead to the result. For instance, some passengers who do not formally complain about the procedures are too busy to file the complaint. Lacking this assumption, the recommendation that a review of the procedure is not important is entirely unfounded.

Even it is granted that the remaining 99 percent passengers have no complaint about baggage-handling procedures , another assumption must be made before we draw the conclusion. We must assume that the percent of passengers who complain about the issue of AVIA Airlines is no higher than that who complain about similar issue of other airlines. Lacking information about other airlines, it is impossible to access the validity of the conclusion.  For example, if almost no passengers complain about the procedures to other airlines, the conclusion that a review is not important would be highly suspect.

Based on the reasons I listed above, the argument is not completely sound. The evidence in support of the conclusion does little to prove the conclusion since it does not address the assumption I have already raised . Ultimately, the conclusion would have been more convincing by making it clear that only 1 percent passengers are unsatisfied with baggage-handling procedures of AVIA’s, and that this proportion in AVIA is not higher than that in others airlines.

划线句好像不对，但我也不知道怎么改，请NN指点。

另外，我正在弄模板，参考了很多224篇范文里的东东，这些范文是不是ETS出的？那我参考了会不会被认作抄袭呀？
