Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: We've heard about radiation from the damaged nuclear reactors in Japan reaching American shores. Experts say so far there is no reason to worry, and point out that we meet radiation every day. Where and how? NPR's Renee Montagne posed that question to Peter Caracappa, a radiation safety officer and professor of nuclear engineering. MONTAGNE: How many things emit radiation? Dr CARACAPPA: Well, radiation and radioactive material is a part of nature. So everything that's living has some amount of radiation coming from it--a very small amout. Plus there's radiation in the ground and the air. So the extremes are uranium in the soil to bananas? Yes. By the way, why do bananas have radiation? Bananas have a lot of potassium . And a small amount of potassium naturally is called potassium 40, which is radioactive What's the difference between radiation that's harmful and not harmful? Well, the term radiation can apply to a lot of different things. But the harmful radiation is ionizing radiation. It has enough energy that it can make chemical changes in material. We could get ionizing radiation from an X-ray, for example. It's the kind of radiation that causes cancer. The broader definition of radiation includes a lot of things that we call non-ionizing radiation. That includes everything like radio waves and visible light and your microwave. So what then is the largest contributor of ionizing radiation? For the natural sources of ionizing radiation, actually the biggest chunk of that tends to come from radon , which is a radioactive material that is present in the air. It can become a concern when it builds up in low-lying areas of homes like basements. Would it be fair to say that most people do not need to worry about the danger of being exposed to radiation? I would say that the everyday exposure to radioation that we meet contributes an extremely tiny risk to our life or to our health compared to all of the other risks that we meet in our day-to-day life. Question: Whether radiation is harmful or not depends on _ . Options: A: whether it has a small amount of potassium B: whether it changes chemical in materials. C: whether it has energy to change materials D: whether it is visible in life
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: The writer Margaret Mitchell is best known for writingGone with the Wind, first published in 1936. Her book and the movie based on it, tell a story of love and survival during the American Civil War. Visitors to the Margaret Mitchell House in Atlanta, Georgia, can go where she lived when she started composing the story and learn more about her life. Our first stop at the Margaret Mitchell House is an exhibit area telling about the writer's life. She was born in Atlanta in 1900. She started writing stories when she was a child. She started working as a reporter for theAtlanta Journalnewspaper in 1922. One photograph of Ms. Mitchell, called Peggy, shows her talking to a group of young college boys. She was only about one and a half meters tall. The young men _ her, but she seems very happy and sure of herself. The tour guide explains: "Now in this picture Peggy is interviewing some boys from Georgia Tech, asking them such questions as 'Would you really marry a woman who works?' And today it'd be 'Would you marry one who doesn't?' " The Margaret Mitchell House is a building that once contained several apartments. Now we enter the first floor apartment where Ms. Mitchell lived with her husband, John Marsh. They made fun of the small apartment by calling it "The Dump " . Around 1926, Margaret Mitchell had stopped working as a reporter and was at home healing after an injury. Her husband brought her books to read from the library. She read so many books that he bought her a typewriter and said it was time for her to write her own book. Our guide saysGone with the Windbecame a huge success. Margaret Mitchell received the Pulitzer Prize for the book. In 1939 the film version was released. It won ten Academy Awards, including Best Picture. Question: Why did Ms. Mitchell stop working as a reporter according to the passage? Options: A: Because she was rich enough. B: Because she was injured then. C: Because her husband didn't like it. D: Because she wanted to write books.
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Doctor Mason has held a clinic for ten years. He is an expert doctor.

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: How much can environment affect intelligence? In one study, striking increases in IQ occurred in 25 children who were moved from an orphanage to more stimulating(,) environments.The children, who were all considered mentally retarded and unadoptable, were moved to an institution where they received personal attention from adults.Later, these supposedly retarded children were adopted by parents who gave them love, a family ,and a stimulating home environment.The children gained an average of 29 IQ points.For one child, the increase was an amazing 58 points.A second group of initially less "retarded" children, who stayed in the orphanage, lost an average of 26 IQ points. Other encouraging results can be found in early childhood education programs, which provide stimulating intellectual experiences for disadvantaged children.In one study, children from low-income families were given enriched environments from early infancy through preschool.By age 2 their IQ scores were already higher than those in a control group.More important, they were still 5 points higher seven years later.High-quality enrichment programs such as Head Start can prevent children from falling behind in school. A particularly striking environmental effect is the fact that 14 nations have shown average IQ gains of from 5 to 25 points during the last 30 years.These IQ boosts, averaging 15 points, occurred in far too short a time for genetics to explain them.It is more likely that the gains reflect environmental forces, such as improved education, nutrition, and living in a technologically complex society. Question: Which of the following is NOT mentioned as an environmental factor that affects IQ _ . Options: A: Good nutrition. B: Improved technology. C: Better education. D: Food pollution.

D
