VI. Read the passage and choose the best answer to each question.             Percy Lebaron Spencer (1894-1970) was an American engineer and inventor. Like several great inventors, Dr Percy Spencer made his most famous discovery by accident. He was testing a new piece of radar technology called “ magnetron” in a laboratory in 1946 when the candy bar in his pocket started to cook. This interested him, so he put some corn next to the magnetron and that cook too !             The next day Dr Spencer and his colleague placed an egg near the magnetron. Dr Spencer’s curious colleague took a step closer to check the egg-just in time for it to explode and cover his face !             After a short time, the company Dr Spencer worked for was trying to find a more controlled way to use this microwave energy to cook food. In 1947, the first microwave oven became available. It was almost two metres tall and weighed over 350 kilos !             Finally in 1966 technology became advanced enough to produce microwaves for everyday domestic use. By then they were such smaller and easier to control. Nowadays you can see microwave ovens all over the world. They are here to stay. 1.Dr Spencer discovered that…………………             A. a new piece was called “magnetron”                     B. a candy bar could cook his pocket.             C. magnetron could cook food                                   D. invention often happened by accident 2.
