Question: Write a multi-choice question for the following article, with the given choices and answer: Article: On May 2, 2012, Ashok Gadgil became the winner of the $100,000 Lemelson-MIT Award for Global Innovation . Each year, the honor is given to an inventor who has made a big difference in the lives of people in developing countries. Gadgil is a professor and physicist at the University of California, Berkeley. He spent thirty years helping people in need. His inventions have helped more than 100 million people around the world. "I chose to focus on problems where my knowledge of science could help," Gadgil said. In the 1990s, Gadgil designed his first life-saving invention after more than 10,000 people died from Bengal cholera because of the clean water crisis in India. His invention uses ultraviolet light to kill deadly disease-carrying germs from drinking water. It costs just one cent to clean five liters of water (about 21 cups). So far, the invention has provided safe drinking water for more than five million people in India and other developing countries. Gadgil's another important invention is the Berkeley-Darfur Stove . The long and violent war in Darfur, Sudan, has caused many people to move to foreign countries and live in refugee camps . They are given food aid. But people still have to travel a long distance five times a week to gather firewood to cook meals. This can be dangerous because of street violence in the area. To avoid danger, some spend much of their money used to feed their families buying firewood. The stove Gadgil created cuts fuel usage by 55%. That means people wouldn't have to leave the camps to find firewood as often. The invention also helps to save homes more than $300 a year. About 125,000 people and their families have been helped. As a professor, Gadgil encourages his students, "Be optimistic when you try a hard problem," he says. "It's when you solve a large problem that you can have a big influence on the world." Options: A He helped about 125,000 people in India. B He spent lots of money on his inventions. C He used his knowledge to help people in need. D One of his inventions could cure Bengal cholera. Answer: C He used his knowledge to help people in need. Question:

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: About ten men in every hundred have the trouble of color blindness in some way. Women are luckier, only about one in two hundred is affected in this matter. Perhaps, after all ,it is safer to be driven by a woman. There are different kinds of color blindness. For example, a man cannot see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can't tell the difference between blue and green. Only a few unlucky men may see everything in shades of green-- a strange world indeed. Color blindness in human beings is a different thing to explain. In only one eye there are millions of very small things called "cones " . These help us to see in the bright light and to tell differences between colors. These are also millions of "rods" ,but these are used for seeing when it is nearly dark. They show us shapes but not colors. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky. With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of the rods we can see shapes at night. Options: A women drive more carefully B women are better at driving than men C women can see things more clearly D there are fewer color -- blind women Answer: D there are fewer color -- blind women Question:
