Q20:
During the past year, Pro-Tect Insurance Company’s total payouts on car-theft claims were larger than the company can afford to sustain. Pro-Tect cannot reduce the number of car-theft policies it carries, so cannot protect itself against continued large payouts that way. Therefore, Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices. Many policyholders will respond to the discount by installing antitheft devices, since the amount of the discount will within two years typically more than cover the cost of installation. Thus, because cars with antitheft devices are rarely stolen, Pro-Tect’s plan is likely to reduce its annual payouts.
In the argument above, the two portions in boldface play which of the following roles?
谢谢!
is the answer A?
different from other BF that have two counteracting arguments or conclusions, this one only involves one argument, that is to reduce total payouts on car-theft claims without dropping any policies which contributed to the current situation.
first BF tells us that it's not possible to drop those car-theft policies(rule out), so the company worked out another way to reduce the payout, then the second BF is the alternative.
是A阿 我选的是B。。。
看了你的解释有点明白
