Passage: Due to the aging population, the German government is facing a dilemma: if the pension system is not reformed, pensions will be unsustainable. Policies to solve this dilemma include increasing the proportion of pension contributions, lowering the level of pension payments, and raising the retirement age. Among them, raising the retirement age has faced the greatest resistance, and governments that implement such a policy may lose a large number of votes in the next election.

B. B.In order to reduce pressure, the German government has stipulated that from 2012, a 20-year transition period will be used to increase the retirement age from 65 to 67
C. C.Delay retirement by one year, and the pension cut can reach nearly 1% of GDP
D. D.The average life expectancy of Germans is now greatly improved, and retirees are receiving pensions for longer and longer
