问题     George Washington Carver showed that plant life was more than just food for animals and humans. Carver’s first step was to analyze plant parts to find out what they were made of. He then combined these simpler isolated substances with other substances to create new products.
    The branch of chemistry that studies and finds ways to use raw materials from farm products to make industrial products is called chemurgy. Carver was one of the first and greatest chemurgists of all time. Today the science of chemurgy is better known as the science of synthetics. Each day people depend on and use synthetic materials made from raw materials. All his life Carver battled against the disposal of waste materials, and warned of the growing need to develop substitutes for the natural substances being used up by humans. Carver never cared about getting credit for the new products he created. He never tried to patent his discoveries or get wealthy from them. He turned down many offers to leave Tuskegee Institute to become a rich scientist in private industry. Thomas Edison, inventor of the electric light, offered him a laboratory in Detroit to carry out food research. When the United States government made him a collaborator in the Mycology and Plant Disease Survey of the Department of Agriculture, he accepted the position with the understanding that he wouldn’t have to leave Tuskegee. An authority on plant diseases-especially of the fungus variety--carver sent hundreds of specimens to the United States Department of Agriculture. At the peak of his career, Carver’s fame and influence were known on every continent.
According to the passage, chemurgy can be defined as______.
选项
答案development of industrial products from farm products
解析 要对关键词chemurgy进行英语释义。如果能用英语进行释义则更好。如果不能，也可从原文中发现对它的解释。如第二段开头一句话就是对这一词汇的解释；raw materials from farm products to make industrial products或development of industrial products from farm products。
