investigators concluded that human failure was not responsible for airplane crash last Augst,and since that time new and more stringent rules for identifying and reporting mechanical problem have beeb in effect.that accounts for the fact that reports of airplane mechanical problem have increased in frequency by 50 percent since last August

which one of the following is an assumption buderlying the argument

1 airplane travel is still safe,despite the inceasing in the reproted mechanical problem

2mechanical problem have inceased dramatically since last Augest

3mechanical problem in airplane have not inceased by 50% since last Augest

4airline are less reluctant to report mechanical problem than they previously were

5mechanical problem have become easier to detect since last August

请高手指点哪个是对了,我没太搞懂逻辑关系

文章说是rules使得机械问题的报告上升了50%

3排除了一种情况,如过是机械问题本身上升了50%,那么使得报告上升50%的就不是rules,从而排除了这个削弱的情况

所以3应该是答案

请问underlying the argument 意思是削弱吗?????我知道undermine是削弱,这到题问的是什么意思啊

which one of the following is an assumption underlying the argument

assumption has been questioned here and you have to find out a premise of this argument here.

underlying is an adj used here to modify assumption.That means assumption is not explicitly listed in the argument and it is the basic condition for this argument.If the assumption is wrong ,then the argument will be wrong correspondingly

好像我有点明白了,就是说因为新的和更严格的标准和规范起了作用,机械问题的报告上升了50%.前提就是机械问题本身没有上升了50%.

如果机械问题本身就上升了50%,机械问题的报告也上升了50%,这样,根本新的和更严格的标准和规范就没起作用.
