Read the article and select the best 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." Question: Which of the following statements about Gadgil is TRUE? 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.

Read the article and select the best answer. Article: When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm and, in the winter especially, we were quite cut off from the outside world. As soon as I left school, I packed my bags and moved to the capital. However, I soon discovered that city life has its problems too. One big disadvantage is money---it costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma , and at times the air is so bad that I am afraid to go outside. Then there is the problem of travelling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous. Of course there are advantages. First, there is so much to do in the city, whatever your tastes in culture or entertainment. Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising---and, what is more, shops are often only a short walk away. Is life better then, in the city? Perhaps it is, when you are in your teens or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem better. I certainly hope to move back there soon. Question: How is the passage mainly developed? Options: A: By inferring B: By comparing C: By listing examples D: By giving explanations2
