新东方补充教材P248第262题
题目如下：
Instead of blamming an airline accident on pilot error,investigators should find out why the error was made by analyzing airplane design,airline managment,and pilot-training programmes.For only then can changes be made to ensure that the same type of error does not recur and cause another accident.
A. Pilot error is not a contributing factor in most airline accidents.
请详细说明A为什么不对，我认为它加强了结论了啊？
小妹有礼了！
