It is more important to spend public money on promoting a healthy lifestyle in order to prevent illness than to spend it on treatment of people who are already ill. To what extent do you agree or disagree?
In the modern world, it is undeniable that governments must decide how to allocate limited public funds within healthcare systems. Some people argue that it is more important to spend public money on promoting a healthy lifestyle to prevent illness, rather than on treating those who are already sick. Although some may disagree with this view, I partly support it due to several reasons, which will be examined in this essay.

Some people think that parents should teach their children how to be good members of society. Others, however, believe that school is the best place to learn this. Discuss both views and give your own opinion.
Some would say that parents should teach their offspring how to be good members of society, while others are of the opinion that school is the best in this regard. This essay agrees with the latter point and will show that, despite the practical experiences that parents give their children, school lessons can give deep insights into what it takes to be good citizens.
