A car’s antitheft alarm tat sounds in the middle of the night in a crowded city neighborhood may stop an attempted ca theft. On the other hand, the alarm might signal only a fault in the device, or a response to some harmless contact, such as a tree branch brushing the car. But whatever the cause, the sleep of many people in the neighborhood is disturbed. Out of consideration for others, people who have these antitheft alarms on their cars should deactivate them when they park in crowded city neighborhoods at night. Which one of the following, if assumed by the author of the passage, would allow her properly to draw her conclusion that the owners of alarm-equipped cars should deactivate the alarms when parking in crowded city neighborhoods at night? (A) The inconvenience of false alarms is small price to pay for the security of a neighborhood. (B) In most cases when a car alarm sounds at night, it is a false alarm. (C) Allowing the residents of a crowded city neighborhood to sleep undisturbed is more important than preventing car theft. (D) People who equip their cars with antitheft alarms are generally inconsiderate of others. (E) The sounding of car antitheft alarms during the daytime does not disturb the residents of crowded city neighborhoods. answer:C my choice:B作者: albert 时间: 2003-8-27 06:02
an assumption should be a required condtion to make the conclusion valid..in other words, making the meaning of the choice you choose as assumption negative, you should find that the conclusion won't hold...otherwise, the choice is incorrect...
C is assumption because if ....is not more important than...., the conclusion won't hold..
so could you explain why you choose B?作者: bigmouse 时间: 2003-8-27 08:51
B的意思应该是在大多数情况下，报警是错误的。我认为这个也是个假设啊？
