Aging poses a serious challenge to OECD (Organization of Economic Co-operation and Development) countries, in particular, how to pay for future public pension liabilities. And early retirement places an【B1】______burden on pension financing. There is no easy solution, but 【B2】______retirement could help. Early retirement may seem like a worthy individual goal, but it is a socially【B3】______one, and makes the present public pension system difficult to sustain for long.

In the next 50 years, low fertility rates and【B7】______life expectancy in OECD countries will cause this old-age dependency rate to roughly double【B8】______size. Public pension payments, which afford 30-80% of total retirement incomes in OECD countries, are【B9】______to rise, on average, by over three percentage points in GDP and by as much as eight percentage points in some countries.【B10】______is the pressure on pension funds that there is a danger of today's workers not getting the pensions they expected or felt they【B11】______for.

After years of【B16】______early retirement schemes to avoid【B17】______and higher unemployment, many governments are now looking【B18】______persuading people to stay in work until they are older. Surely, the thinking goes, if we are healthier now and jobs are physically less【B19】______and unemployment is down, then perhaps the【B20】______rate should rise anew.
【答案解析】解析:考查名词辨析。根据下文“In the next 50 years”可知,接下来是对将来可能发生情况的预测,A.outlook意为“前景”,符合文意,代入句中,表示“这一前景是令人担忧的”。故答案为A。outcome“结果”;outbreak“(战争的)爆发,(疾病的)发作”;outset“开始,开端”,均不符合题意。
