CEPT Practice B2 Level Read and select about a woman at number 20

 

The woman at number 20 was no doubt mindful of a crime prevention circular she had received very recently and said that she would expect them to know whether she had a water meter if they were genuine employees of the water company. The tall man from the van showed a card to the sceptical woman, which seemed to satisfy her. She went into her house and left them to it. The three men busied themselves in the driveway of number 18. They raised a manhole cover, then one man got a toolbox from the van, went round the side of the house and into the back garden. After a few minutes the front door opened and he appeared at it, signalling to his colleagues. The tall man closed the manhole cover, took another toolbox from the van and went to the doorstep. He glanced around, then he also entered the house, leaving the front door ajar. The third man reversed the van into the driveway.
