Which of the following most logically completes the argument below?

When interest rates are high, insurance companies reduce the premiums they charge for many kinds of insurance policies.The reason is that insurance companies want to take in as much money as possible in premiums so that they can invest the money at high rates of interest.And premium reductions help achieve this objective, since __________.

(A) interest rates are likely to decrease when large amounts of money are available for loans

(B) smaller insurance companies are not able to amass enough money to take advantage of investing at high interest rates

(C) insurance companies can sell many more insurance policies if they charge lower premiums than they would if they left premiums unchanged

(D) an increase in the number of policies sold eventually leads to an increase in the number of claims that an insurance company has to pay

(E) the number of claims that insurance companies pay increases at a higher rate than does the number of policies that the insurance companies can sell at the lower premiums
答案是C，哪位可以帮忙分析一下~感激不尽!

文中前两句话说，当利率高时，保险公司会降低premium，因为这样可以收到尽可能多的钱来投资。然后建立两者之间桥梁就可以了，总体收入是premiums 和 insurance policies 的成绩，虽然前者降低些，但是后者如果以一个更加大的幅度上升，总体还是会上升的。C项就说明了这点。

这道题就是要在降低保费和增加收入间找到一个理由来衔接，所以C选项就说，降低了保费就会促使人们买更多的保险，于是保险公司总收入就会增加（和我们熟知的减价促销会增加总的销售收入一个道理）
