11月27日，广州杀G，JJ AA： The following appeared in an Avia Airlines departmental memorandum: “On
average, 9 out of every 1000 passengers who traveled on Avia Airlines in
1993 filed a complaint about our luggage-handing 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.”
Discuss how logically convincing you find this argument. In explaining your
point of view, be sure to analyze the line of reasoning and the use of
evidence in the argument. Also discuss what, if anything, would make the
argument more sound and persuasive, or would help you to better evaluate
its conclusion.
