Read the following article and select the best answer. Article: Air pollution is one of the hottest topics at present because poor air quality is an important factor in both the incidence and cause of respiratory  diseases. Zhong Nanshan, a deputy to the NPC and a member of the CAE, said recently when the concentration of PM2.5 rises by 10 micrograms per cubic meter, hospitalization may rise by as much as 3.1 percent. Meanwhile, when the concentration of PM2.5 rises from 25 mgs per cubic meter to 200, the average daily death rate may rise to 11 percent. Zhi Xiuyi, a leading expert in lung cancer treatment and also vice-president of the CATS, said medical authorities used to focus on tobacco control as a primary means of preventing lung cancer. "But in fact, air pollution is no less harmful than smoking and our research team released a report earlier this year showing that the cancer rate in Beijing is closely related to industrialization," he said. The report, conducted by the Beijing Institute of Cancer Research, shows that the number of cancer patients in China has increased markedly during the past ten years. Chaoyang District, the city's main area of industrialization, has the highest incidence of cancer, almost double that of Yanqing, an area on the outskirts of the city. About four out of 1000 Chaoyang residents have some form of the disease, with lung cancer at the top of the list. "The risk of having cancer largely depends on the length of exposure and the concentration of noxious gases ," said Zhi. In response to the doubt whether seven years' exposure to poor air quality will almost result in cancer, Zhi said the time scale was taken from research overseas that suggested the rate of incidence generally peaked in the seventh year of exposure to a heavily polluted environment. Question: If there were 3,000,000 people in Chaoyang District, how many would have respiratory diseases? - 16000 - 12000 - 8000 - 7500
(Answer)
12000

Read the following article and select the best answer. Article: The Mona Lisa, one of the world's most famous paintings, has been recreated with 3,604 cups of coffee--and 564 pints of milk. The different colors were created by adding no, little or lots of milk to each cup of black coffee. The recreated Mona Lisa measured 20 feet long and 13 feet wide. It took a team of eight people three hours to complete the work. It was created for The Rocks Aroma Festival in Sydney, Australia, and seen by 130,000 people who attended the one-day coffee-lovers event. Elaine Kelly, one of the organizers from the Sydney Harbor Foreshore Authority, was delighted with the result. She said, "Each coffee cup was filled with varying amounts of milk to create the different shades  of the painting. We wanted to create an element of surprise and a sense of fun in the way we communicated with the public." "Once we had the idea of creating an image  out of coffee cups we searched for something iconic to reproduce .And after some time we chose the most iconic painting in history. The Mona Lisa has been reproduced so many times in so many different mediums but, as far as we know, never out of coffee," Kelly continued. "Besides, the idea is practical." "It was fantastic. It really looked like the famous painting--the Mona Lisa. It was wonderful," said one visitor. After much planning it was great to see it coming together so well and the 130,000 people who attended the event certainly enjoyed it and were deeply attracted by it," said Kelly. Question: The people who saw the recreated Mona Lisa are all  _   lovers. - Mona Lisa - milk - coffee - painting
(Answer)
coffee

Read the following article and select the best answer. Article: Donald was not very good at maths. He could not understand the teacher's explanations. Even when the teacher explained something a second time, Donald still could not understand it. "Never mind," Donald told himself. "I'm quite good at other subjects. I'll cheat in the maths exam, then I won't be in trouble." "I will sit next to the boy who's best at maths," he thought, "and copy down his answers." The day of the exam came, and Donald sat next to Brian Smith, who always was at the top of the class in maths. Donald carefully copied Brian's answers onto his own exam paper. At the end of the exam, the teacher collected the papers and graded them. Then she said, "Well, boys and girls. I've decided to give a prize to the student who got the highest grade. However, it's difficult for me to decide who to give the prize to, because two students, Doanld and Brian, got the same grade." "Let them share it," one of the other students said. "I have thought about that," the teacher said, "but I have decided to give the prize to Brian." Donald was angry when he heard this. He stood up and said. "That is not fair. I got the same grade as Brian." "That is true," the teacher said. "However, Brian's answer to Question 18 was 'I don't know,' while yours was 'Neither do I.'" Question: Donald got the same grade as Brian because   _  . - both boys were good at maths - Donald cheated - Brian copied Donald's answers - the question were very easy
