A country ’ s Aeronautics Board (AB) employs inspectors who make routine annual inspections of all aircraft. On inspecting Azura Airlines’ airplanes in December, they reported considerably more violations of AB rules this year, compared to a year ago. This fact explains why Azura had more accidents this year, compared to last year.

Which of the following, if true, would cast most doubt on the conclusion in the passage?



Some aviation experts in other countries consider certain AB rules to be too lax and too easy to get around.

Azura’s routes are no more dangerous than are those of most other airlines.

The AB increased the length and rigor of its inspections this year, compared to last year.

Prior to last year Azura had an excellent safety record with very few accidents.

In both years the AB report on Azura did not include violations on airplanes owned by Azura but leased by another airline.
