Read the following passage and circle A, B, C or D to indicate the correct answer to each of<br />

the question from 36 to 42<br />

George Washington Carver showed that plant life was more than just food for animals and<br />

humans. Carver’s first step was to analyze plant parts to find out what they were made of. He<br />

then combined these simpler isolated substances with other substances to create new products.<br />

The branch of chemistry that studies and finds ways to use raw materials from farm<br />

products to make industrial products is called chemurgy. Carver was one of the first and greatest<br />

chemurgists of all time. Today the science of chemurgy is better known as the science of<br />

synthetics. Each day people depend on and use synthetic materials made from raw materials. All<br />

his life Carver battled against the disposal of waste materials and warned of the growing need to<br />

develop substitutes for the natural substances being used up by humans.<br />

Carver never cared about getting credit for the new products he created. He never tried to<br />

patent his discoveries or get wealthy from them. He turned down many offers to leave Tuskegee<br />

Institute to become a rich scientist in private industry. Thomas Edison, inventor of the electric<br />

light, offered him a laboratory in Detroit to carry out food research. When the United States<br />

government made him a collaborator in the Mycology and Plant Disease Survey of the<br />

Department of Agriculture, he accepted the position with the understanding that he wouldn’t<br />

have to leave Tuskegee. As an authority on plant diseases – especially of the fungus variety –<br />

Carver sent hundreds of specimens to the United States Department of Agriculture. At the peak<br />

of his career, Carver’s fame and influence were known on every continent.<br />
