Paper 1
Question 1

The following is an extract from a police interview. The speaker is a witness to events immediately preceding a road trafffic accident in which someone was seriously injured. Please read the extract and then answer the question at the end, giving reasons for your answer:

"I was stopped at some traffic lights. The lights turned to green and I started to move off. As I did so, this coked-up boy racer came zooming past me. He was already doing about 50 and looked like he had his foot down. He just missed some pedestrians. He was laughing like a maniac and didn't seem to know where he was or what he was doing. I was terrified. I remember thinking 'Jesus! He's going to hit someone!' I carried on for a bit and sure enough a few minutes later when I caught up with him I saw he'd collided with that bus."

What, do you think, the police will feel are the crucial bits of this account? What is the most important and relevant information that it contains?

1. The witness was travelling in the same direction as the other car.
2. Something else.
