Answer:
My brother came 1 up 2 with a ‘brilliant’ scheme to make money at school. He 3 conceived a crazy idea to buy sweets and chocolate in a local shop then sell them at a profit to students at his school. I don’t know how he dreamed 4 up this idea, but I thought it was stupid. I tried to 5 change his mind, or, at least, make him 6 reconsider his decision, but he had 7 made up his mind to go 8 ahead with the plan. Once he’s 9 made a decision, my brother never has 10 second thoughts. Of course, the plan failed. He bought lots of expensive sweets but nobody at his school wanted to buy any from him!
