A moment after Ruth knocked on the door, Dr Johansson opened it and led her excitedly inside. She had called him the day before to A21 check a few facts for an article she was writing for the newspaper - Dr Johansson was a leading expert in physics - and he had invited her to go and see his latest experiment. At first, she had tried to A22 get out of it, remembering the hours of physics lessons she had sat through at school. However, he had insisted A23 on seeing her, saying that she wouldn't regret it. As they walked into the laboratory, Ruth wondered exactly what she was letting herself in for. A cat sat on a workbench. It opened one eye lazily and looked at her. There was a black box connected to a computer and another black box on the other side of the room.

'Now, Miss Evans,' said Dr Johansson, with a slight foreign A24 accent 'What you are

about to see may change the world forever!'

Ruth smiled politely. It sounded like a bad film script and she was quickly A25 coming to the conclusion that he was slightly mad. Dr Johansson must have sensed her disbelief.

'Ah, I see you are not sure. That is natural. However, A26 once you have seen my

invention, you will have no doubts.' He pushed a couple of buttons and a low hum filled the room. 'I have been A27 conducting experiments on this for three years, and finally I have succeeded.'

'Experiments on what?' asked Ruth. Dr Johansson picked up the cat and placed it in the black box, closing the lid gently. He stood Ruth next to the other black box.

'The transportation of a living creature!' Dr Johansson said triumphantly, and he pressed a final button. There was a spark of electricity in the air. He opened the box and the cat had disappeared. 'You ... you've killed it!' Ruth shouted. Dr Johansson smiled and pointed to the black box next to her.

He A28 told her to look inside. She slowly lifted the lid. The cat looked up at her as if it was used to this kind of treatment, then closed its eyes and settled down for a nap.
