标题: LAST-27-4-12[求助]
12. The school principal insisted that students failures are caused by bad teaching. In a relatively short time failing grades disappeared from the school. The principal happily recognized his as evidence that the teaching had improved at the school.
The flawed pattern of reasoning in the above is most similar to that in which one of the following?
(A) The nutritionist insisted that the weight gain that team members complained of was caused by overeating. In a brief time all the members stopped overeating. The nutritionist was pleased to conclude that they had stopped gaining weight.
(B) The manager insisted that the worker who files complains had too many difference tasks. The manager simplified the jobs, and complains stopped. The manager happily concluded that the working environment had been improved.
(C) The nutritionist insisted that the weight gain that team members complained of was merely in their imagination. Members were given weight charts for the last three months. The nutritionist was pleased to conclude that the complaints of weight gain had stopped.
(D) The manager insisted that the workers who filed complaints did not have enough to do. Soon there were no more complaints filed. The manager was pleased to conclude that the workers were now productively filling their time.
(E) The nutritionist insisted that the weight gain that team members complained of was cause by their thinking of food too often. The nutritionist was happy to conclude that the weight gain had stopped once the team members reported that they had stopped thinking of food so often.
答案为D, 请问原文的错误与D在哪点类似

谢谢

原文错误:A-->B
得出:非A-->非B
错误.D也犯了这样的错误.complaint(A)-->have enough time to do(B)
now haven't complaint(非A)-->filing time(非B)

谢谢答复. D的推理比较明了, 但对原文有疑问
students failures are caused by bad teaching
bad teaching是原因 students failures 是结果.窃以为 bad teaching--> students failures 不知应该怎样思考才能得出students failures--> bad teaching

说一下我的想法，大家讨论。
根据题目，
The school principal insisted that students failures are caused by bad teaching
学校校长坚持认为学生们学习不好是由于教学差。
students failures（A） --》bad teaching（B）
我是从意思上分析的，
否则如果B是A的充分条件的话，那么题目的逻辑就没有错误了呀。

原文并不是充分必要关系，而只是因果关系。前者有推理关系，后者没推理关系。有些书讲无因无果之类，那是误导的。原文的错误是犯因果方面的错误。
