Question: Read the following article and answer the question. Article: Have you ever heard of Back-to-Front Day? It is a festival in Britain. On that day, the adults have to go to school. And the children? They are the policemen and firemen; they sit in the offices and call New York and Paris; they are doctors and nurses. "Stand in the corner, Mr. Bass!" said Mary. Mary was six and had a class of twenty-three men and fifteen women. They were making too much noise. John was a policeman. Though his uniform was too big, he walked down the street with pride. "Hm, why are you not at school?" "Oh, I ... I have something important to do," said the man. "Fiddlesticks !" said John angrily. He took out his notebook. "Name?" he asked. "Mr. Green." John wrote it down and blew his whistle and a police car appeared. "I have a _ here," said John. "Drive him to school!" At the hospital a small doctor climbed on one chair in order to examine Mrs. Brown's throat, and Nurse Jenny took Granny Lisa's temperature. The best part of Back-to-Front Day is in the evening. The children put the adults to bed, very early. They tell them a story, too -- after the adults wash their faces and brush their teeth. How interesting Back-to-Front Day is!

All they have to do is to put the right chip into the e-schoolbag and press the button. It is said that e-schoolbags have been put into use in some Chinese middle schools. In 2012, some students in Shanghai started to use e-schoolbags in the new term. Some say that e-textbooks can be easily broken. Some say it is not good to students' eyes.

Q: Read the following article and answer the question. Article: Stop. Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound. Noise can be caused by many kinds of machines, such as motorcycles, jet planes and farm tractors . Rock music is also noise. What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant loud noise can cause a loss of hearing. Scientists use a unit of measure called decibel to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level causes the great hearing loss. Question: We can conclude from the passage that _ . Answer:

Q: Read the following article and answer the question. 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: What do people benefit from the Berkeley-Darfur Stove? Answer:

OPTIONS:
- They can sell stoves to make a living.
- They can save both time and money.
- They can be protected from diseases.
- They can cook their food easily.

A:
They can cook their food easily.
