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.
这题很像监视那一题，监视器更多了，犯罪更多了，其实不是犯罪更多了，而是发现犯罪的更多了因为安装了更多监视器能witness更多犯罪；同理这题也是一样，不是今年的事故更多由于violation更多，去年可能violation跟今年一样多，事故少，但是由于今年更严格的AB审查，导致发现的violation更多，所以才造成假象今年violation导致事故变多
要是有点赞功能就好了哈哈哈

原文结论：违反rule次数多，所以事故多
削弱（用他因）：今年更严格的AB审查→发现的violation更多
原文结论：违反rule次数多，所以事故多
削弱：事故发生的原因是其他；rule本身变多，变严格了
啊，你这个削弱说的是违反rule次数多的原因吧

premise ”more violations of AB rules “ -> conclusion "This fact explains why Azura had more accidents"
错在没读懂题干和逻辑关系，选项引入他因->AB延长了
C. Correct. This statement provides an alternative reason that the number of violations for Azura Airlines would have increased. That is, if the AB conducted more extensive and more rigorous inspections this year, then it is very likely that the number of violations found by the AB would increase. In other words, if more points are tested or existing tests are made stricter, then the increase in rigor of the testing would presumably lead to an increase in violations.
