The following question asks for your opinion. You can either have a strong opinion or a more balanced opinion, but you should definitely make your opinion clear in your introduction.
Governments should not have to provide care or financial support for elderly people because it is the responsibility of each person to prepare for retirement and support him or herself.
To what extent do you agree or disagree with this opinion?
Introduction (strong opinion):
People have different views about whether or not governments should help senior citizens. I completely disagree with the idea that elderly people should receive no support from the state.
Introduction (more balanced opinion):
People have different views about whether or not governments should help senior citizens. Although I accept that we all have a responsibility to save money for retirement, I disagree with the idea that elderly people should receive no support from the state.
After the first introduction, I'd advise you to write 2 paragraphs that both explain why you disagree. The second introduction allows you to discuss both sides (which might be easier).
