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
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
问题分析：还是完成句子，仔细看看最后一句话给我们的提示，说premium reduction能实现目标的原因？答案怎么样也得和premium reduction有点联系，我们根据这个提示来看选项。
A就和premium reduction没有关系，杀。
B也和premium reduction没什么关系，杀。
C说过charge lower premiums，和提示有点联系，留着。
D也和提示没关系
E虽然说了lower premiums但是整体意思强调的是两种保险公司数量的对比，没提，干掉！
