根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
A serious problem for today’s society is who should be responsible for our elderly and how to improve their lives.It is not only a financial problem but also a question of the system we want for our society. 
First,employers should take the responsibility for their employees. But when a company must take life-long responsibility for its employees,it may suffer from a commercial disadvantage due to higher employee costs.
  This means each person must  save during his working years to pay for his years of retirement.This does not seem a very fair model since some people have enough trouble paying for daily life without trying to earn extra to cover their retirement years.This means the government might have to step in to care for the poor.
In addition, the government could take responsibility for the care of the elderly.This could be financed through government taxes to increase the level of pensions.Furthermore,some institution should be created for senior citizens,which can help provide a comfortable life for them.  
The government can seldom afford to care for the elderly,particularly when it is busy trying to care for the young.
One further solution is that the government or social organizations establish some working places especially for the elderly where they are independent.
Therefore,it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations.

A．Every coin has two sides

B．To sum up,all these options have advantages and disadvantages.

C．I would like to suggest several possible solutions to this problem.

D．It’s unfair to let the government to share all the responsibilities.

E.      To make this possible,a percentage of profits should be set aside for this purpose.
F.      Another way of solving the problem is to return the responsibility to the individual.
G.  Unfortunately,as the present situation in our country shows,this is not a truly practical answer.
