Read the text about the discovery of radioactive decay. For gaps one-9 cull the correct answer A-D.
The Discovery of Radioactive decay
In 1896 the French physicist Antoine Henri Becquerel1________ investigating uranium salts. He accidentally left a bit of uranium lying on some photographic plates – glass plates which were used in photography earlier motion-picture show wasii________.
three________ the plates were wrapped in thick black paper to protect them from calorie-free, afterwards some time Becquerel constitute out that they had been exposed, just equally if they had been lying in the sun. He asked himself how thisiv_________ happened. He repeated the experiment and finallyfive________ to the conclusion that the uranium table salt emitted unknown rays, similarsix________ Ten-rays, which could pass through thick black paper. In this fashion radioactivityvii________ discovered.
The story shows some of import qualities of a scientist's mind: the desire to sympathise why something happens the fashion it does, and the imagination which made Becquereleight________ of a won the Nobelnine________ in Physics for his discovery.
