Read the following passage carefully. Of all the weapons of destruction invented by science till today, the most destructive one is the Atom bomb. Scientists have succeeded in making this after years of research. These researches first started in Germany about the beginning of the Second World War. The German scientists were afterwards engaged by America, and a big laboratory covering several square miles was set up in that country. Constant researches were carried on in America very secretly and in 1944, the scientists succeeded in making the Atom bomb. During that time the Second World War was almost coming to an end. Germany was defeated. But the small country, Japan, was still waging the war against the mighty forces of England, France and Russia and America was forced to enter the war.
