Article: London has always been known for its "black fogs". In the winter of 1952, a milky white fog rolled into the city. As the smoke poured into the air, it was so hard to see that people had to walk in front of the buses to guide them. In this way, the most serious air pollution disaster in history began. When it was over, more than 4,000 people had been killed by the thick black smog. New York City has had several London-type smogs since 1950. Each time, 100 to 400 deaths were caused by the smog. Although these smogs were not as deadly as London's, New York City has the worst air pollution problem in the United States. In all the killer smogs, factories and homes poured smoke and fumes into the air from the furnaces. The chemical fumes combined with the water droplets in the fog to form harmful substances. These substances caused the illness of those who breathed the polluted air. Usually, such harmful fumes rise into the upper air and are blown away by the wind. But sometimes there is an unusual weather condition called a temperature inversion. A layer of cold air remains near the ground as smoke and fumes pour into it. This is covered by an upper layer of warm air that acts like a lid. It prevents the polluted cooler air from rising. The harmful fumes pile up and make people ill. The smog may be so thick that airports are closed and chains of collisions occur on the highways. Another type of smog occurs in Los Angeles. Here the weather may be clear and sunny. But stinging eyes and dry coughs show that harmful chemicals fill the air. The smog is due to invisible gases, mostly from automobile exhaust. Because these chemicals are changed by the sun high up in the air, it is called photochemical smog. It contains automobile exhaust fumes and nitrogen oxides changed by the sun's rays. Added to these are sulfur dioxide and other fumes from factories and oil refineries. Photochemical smog is found in many large cities all over the world. Killer smogs don't happen very often, fortunately. But in Beijing, a combination... Question: What can reduce the air pollution according to the passage'? Yes or no, is the answer "Wind."?
Yes

Article: Dick was a twenty-year-old man. His father was a teacher and taught chemistry in a middle school and his mother worked in a shop. They lived a happy life until his parents died one night when suddenly an earthquake broke out. Luckily his sister took him to see their aunt in the city and they did not stay at home. Everything was destroyed in the earthquake and the two children got into trouble. Thanks to their aunt who was not rich enough, they grew up but they lived a hard life. His sister was so sad that she became a nun . After he finished middle school, he was introduced to an owner of a hotel and began to work there. One day the young man fell to the ground while he was cleaning a window on the second floor. He was sent to the hospital and the doctor looked him over. One of his legs was broken and he had to be in hospital. He said to the nurse, "I'm a poor man, madam. Arrange a third-class ward for me, please." "Can't anybody help you?" "No, madam," answered Dick. "I have only a sister. She's a nun and she's poor, too." "I don't think so," the nurse said angrily. "Nuns usually marry God. And God is the richest in the world, you know!" "Well, then," Dick said with a smile. "Please arrange a first-class ward for me and post the bill to my brother-in-law." Question: Which of the following is true? Yes or no, is the answer "The nurse would arrange a third-class ward for Dick."?
Yes

Q: Article: Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true. People who studied plants have found out that plants carry a small electrical charge . It is possible to measure this charge with a small piece of equipment called "galvanometer". The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened. A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them - perhaps by pulling off its leaves or by pulling it out of its pot - then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects . Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room. Another scientist, named Sauvin, achieved similar results to Backster's. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them. Question: Backster was surprised at the results of his studies because _ . Yes or no, is the answer "he found that plants could express feelings of shock"?
A: Yes

Article: A company has just launched what it calls "the world's first free standardized English test" recently. Anyone can take the test for free. The new exam is called the EFSET, which is short for Education First Standardized English Test. The company, Education First, is known by the letters EF. It is estimated that there are two billion English language learners worldwide. Many of them are interested in attending an American college or university. To do so, foreign students need to take the Test of English as a Foreign Language -- better known as TOEFL. However, many foreigners are not wealthy enough to take the TOEFL. In addition, test-takers often have to travel overnight to reach an official testing site. The World Bank says an average Cambodian worker earns only about $1,000 per year. Approximately the cost of taking the TOEFL is 17.5 percent of the average worker's yearly wage. It is not just individuals who find the test pricey. Some governments also find it prohibitive. What's more, not everyone needs official results from the TOEFL or IELTS -- the International English Language Testing System. In the future, it's likely that the government may use the EFSET to test millions of employees and students. Experts believe that the EFSET meets the highest value in language testing. It uses special computer software that makes the questions easier or harder, depending on one's performance. The EFSET measures all the English learners' levels while the IELTS and TOEFL only measure learners' levels from moderate to advanced. The EFSET is unique in the sense that it gives free online access to anyone interested in measuring their English level. There is a 50-minute and a two-hour version of the test, which its developers are calling the EFSET Plus. Both versions test only reading and listening skills. It's hopeful that speaking and writing skills will be tested in the future. The IELTS and the TOEFL still use humans to rate the speaking and writing sections. It's a huge deal for students who are in areas where they... Question: Why do many foreign students take the TOEFL? Yes or no, is the answer "To receive further education in America."?
