听力原文: The police released the first video images yesterday of the two men believed to have been involved in robbing a jewelry shop in the city seven days ago. But the video pictures taken a week ago were not very clear. The camera which filmed the men was about 200 metres away from a parked lorry which the robbers later used as a getaway vehicle18. The men were also filmed wearing hoods as they ran towards the lorry after the robbery.
The pictures are timed at 9. 05a. m. last Saturday just half an hour before the robbery occurred. Witnesses have confirmed that at some time during this half-hour, they saw the two men, without hoods, leave the lorry separately19. Despite the quality of the video, the police believed that the robbers are distinct enough to be identified. The first suspect, who got out of the driver's side of the lorry, was about 5 foot 6 inches tall, and fat. He was wearing a grey jacket, with a hood, and dark trousers. The passenger was slimmer, and slightly taller20 , about 5 foot 8 inches, and was wearing light-blue jeans and a white jacket with a hooded jogging top. According to the police, the lorry, stolen in the parking lot of the city mall last month, had been repainted from white to somber, and fitted with false registration plates20.
Where were the two men filmed?
A.In the jewelry.
B.In the City Mall.
C.Near the lorry.
D.In the parking lot.
