此题在OG12上的正确答案为A 当时做OG时我也错选了C 花了好些时间弄懂原因 说一下原因: 先看题干,问的是 if carried out, will have the announced effect 那就回原文看到底announced effect是什么(lawyer前辈说过,要特别注意结论的具体性和特殊性)
最后一句:Removing the boxes will reduce thenumber of prank calls without hampering people’s ability to report a fire即为announced effect 这句话包含两层意思: 1、reduce thenumber of prank calls 2、will not hampering people’s ability to report a fire.
看A:traces all alarm calls made from private telephones会使人们不敢谎报火灾,满足1的要求,records where they came from 则满足2的要求 再看C: 不难发现它只满足2的要求而不满足1的要求
