问题    Today much rubber is synthetic. It would seem that there would be less opportunity for accidents in creating this artificial product. Nevertheless the first synthetic rubber was produced by accident, an even stranger accident than that which happened to Charles Goodyear.
   In 1917, Professor Harry L. Fisher, a teacher of organic chemistry at Columbia University, was asked by the United States War Department to prepare chemical compounds, The War Department planned to test these compounds in order to decide how effective they would be against an enemy. Fisher was given a list of 20 such compounds, and number 13 on the list was a chemical made with sulfur. Some people think that is an unlucky number, and Fisher thought it was when he first heated the chemicals in his laboratory The result was a bad - smelling, sticky substance that certainly had no military value. But it became the first of the synthetic rubbers to be produced in large quantities.
   The invention of the automobile and the tube tire caused the rubber business to grow greatly. The growth of the electric industry, was great also, for it uses synthetic rubber as a covering fur wires. Goodyear died still owing 200,000 dollars, but the company having his name grew to one doing business everywhere in the world and earning millions and millions of dollars. And it all began when Goodyear serendipitously dropped some rubber on a hot stove.
选项 A、the first synthetic rubber was produced by Charles Goodyear
B、if it had not been for a traffic accident, we would not have had synthetic rubber
C、more need for rubber helped the development of synthetic rubber
D、the first synthetic rubber came into being totally unexpectedly
答案D
解析 细节判断题。文中第一段主要告诉我们合成橡胶本来似乎没有机会问世，但其诞生比Goodyear制作的天然橡胶成品更具有偶然性，其它各项选拦都有与事实不符之处。
