Let us think and reflect

I Read the extracts given below and answer the questions that follow.

1. Before beginning this story, let me put you in the picture. I am Anita, fourteen years old. My brother Anand, one year younger than me, caused all that hoo-ha with his burglar alarm. The trouble with him is that he thinks he is a scientist. He loves tinkering with all sorts of electrical gadgets, tools, dynamos, planks of wood, and things like that. And he keeps creating ‘inventions’ that never work out as they are supposed to.
