Undergraduate / What would you do to improve the world? - Trinity College Schorlaship [4]

Hello there!

I'm now participating in a big game sponsored by Trinity College, Australia. All I have to do is write an essay within 500 words.

Here is the topic: " IF YOU HAD THE POWER TO DO ONE THING TO IMPROVE THE WORLD, WHAT WOULD YOU DO? DISCUSS "

I've made up the outline. Creation is my favourite. Therefore, I intend to write a story. It's exactly a conversation between two characters and I want to express my discussion inside it. I'm afraid that it's not the right form of an essay so I really need some advice to complete my essay.

Could you please help me? Thank you very much
