标题: help, a LSAT CR, [打印本页] 作者: hexin 时间: 2003-4-7 09:33 标题: help, a LSAT CR, 16. Investigators concluded that human failure was not responsible for the fatal airplane crash last August, and since that time new and more stringent rules for identifying and reporting mechanical problems have been in effect. That accounts for the fact that reports of airplane mechanical problems have increased in frequency by 50 percent since last August. Which one of the following is an assumption underlying the argument in the passage?
(A) Airplane travel is still relatively safe, despite the increase in reported mechanical problems. (B) Mechanical problems in airplanes have increased dramatically since last August. (C) Mechanical problems in airplanes have not increased by 50 percent since last August. (D) Airlines are less reluctant to report mechanical problems than they previously were. (E) Mechanical problems in airplanes have become easier to detect since last August.
Whoe can tell me why the answer is C, I don't know what is the argument in this passage. Thanks!作者: cranberry 时间: 2003-4-7 21:49
the argument is the rules cause the 50% more reports about problems作者: cranberry 时间: 2003-4-7 21:54
it implies that there may not be so many problems actually作者: hexin 时间: 2003-4-7 23:56
thanks cranberry. Now I see.
