Re: PT 58 Section 1 #18
Cheap airlines have few accidents, but they have not been in business long enough to have established safety records
Major airlines have reliable, long standing safety records.
Therefore, passengers of major airlines are safer than those of new, cheap airlines.
A: if the number of total accidents were the same, major airlines would be safer because they've been operating longer. This can't be a criticism
B: reliable, long standing safety records are not too brief a period to draw a conclusion about safety
C: This is correct, because it is the case that the travel agent infers the safety of major airlines merely from the EXISTENCE of records, without considering the content of those records
D: The travel agent says in essence "because major airlines have long standing records (that, as it so happens are reliable), they are safer. The fact that they are reliable is not the reason for his inference
E: One or more accidents would not necessarily mean that the inference that the airline is safe is incorrect.
