In conclusion, the arguer fails to demonstrate that a review of the baggage- handling procedures at Avia Airlines is not needed to maintain or increase the number of Avia s passengers. To strengthen the argument, the author
would have to provide evidence that most Avia passengers last year were
indeed happy with baggage-handling procedures. To better evaluate the argument, we would need more information about the numbers of Avia passengers per flight last year and about the baggage-handling records of Avia s competitors.
