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?

A. Some aviation experts in other countries consider certain AB rules to be too lax and too easy to get around.
B. Azura's routes are no more dangerous than are those of most other airlines.
C. The AB increased the length and rigor of its inspections this year, compared to last year.
D. Prior to last year Azura had an excellent safety record with very few accidents.
E. In both years the AB report on Azura did not include violations on airplanes owned by Azura but leased by another airline.

OA C

Premise: A country's Aeronautics Board (AB) employs inspectors who make routine annual inspections of all aircraft.

Conclusion: On inspecting Azura Airlines' airplanes in December, the inspectors reported considerably more violations of AB rules this year, compared to a year ago.

OPTION A - INCORRECT
The opinion of some aviation experts in other countries concerning AB rules is not in accordance with the passage.

OPTION B - INCORRECT
Neither do we know about Azura routes nor the routes of other airlines as no information was given about routes. Hence, we can't know if Azura routes are no more dangerous than those of other airlines.

OPTION C - CORRECT
This objection weakens the argument the most because it wasn't stated that the country's Aeronautics Board (AB) carried out their inspections rigorously this year, compared to last year. We only know about the routine annual inspections of all aircraft.

OPTION D - INCORRECT
This option is wrong because Azura had more accidents this year compared to last year.

OPTION E - INCORRECT
The inspection carried out on Azura airlines reported more violations of AB rules this year compared to a year ago. Hence, we don't know about violations of airplanes owned by Azura but leased by other airlines.
