1) As I was walking along THE street, I saw A hundred rupees note on THE road. ( I guess you missed on)
2) I saw AN accident this morning.
A car crashed into THE wall.
3) When you turn............... A pink one, A blue one, and A white one. I live in THE pink one.
4) We liven in AN old house in THE middle of the city. There is A beautiful garden behind THE house.
5) I have A cat and A dog. THE dog never bites anyone, but THE cat often scratches THE dog.
