And early retirement places an【C1】______burden on pension financing. There is no easy solution, but【C2】______retirement could help.
   Early retirement may seem like a【C3】______individual goal, but it is a socially expensive one, and makes the present public pension system difficult to sustain for long. The【C4】______reason is that more people are retiring early and living longer. That means more retirees depending on the funding of those in work for their【C5】______, The【C6】______is worrying. In the next 50 years, low fertility rates and rising life expectancy in OECD countries will cause this old-age dependency rate to roughly double in size.

【C7】
选项 A、invest
B、deduct
C、afford
D、cost
答案C
解析 本题考查上下文语义。空格所在部分是which引导的非限制性定语从句，修饰先行词public pension payments，表示“……全部退休收入30％一80％的公共退休金款项”。从上文我们知道，退休人员依赖在职者的支付而获取养老金，而在职者缴付的即是“公共退休金款项”，他们缴付的这些资金构成了退休人员全部退休收入的30％一80％。因此，只有afford此处表示provide sb．with sth．，符合文意，为正确答案。
