Question: Read the following article and select the best answer. Article: London--coffee protects mice from radiation and could get the same way in humans, according to Indian scientists. Scientist at India's Bhabha Atomic Research Center discovered that mice injected with caffeine remained alive after high doses of normally _ radiation. Although the study was limited to animals, Kachadillilli George, head of the research team, believes the findings could have implications (something suggested ) for humans . "It does suggest that coffee might have some beneficial effects in protecting against radiation," he told New Scientist magazine late last month. George and his team injected 471 mice with caffeine and left them uncovered to 7.5 grays of gamma radiation ,enough to kill most mice. But 25 days later 70 percent of the mice that had received 80 milligrams of caffeine per kilogram of body weight were still alive. On the contrary all 196 mice that had been left uncovered to the same radiation but had not been given any caffeine died. Question: From the news, we know _ can be protected from radiation. - both mice and humans - only mice - only humans - neither humans nor mice
Answer: both mice and humans

Question: Read the following article and select the best answer. Article: A "blogger" is a person who writes on an Internet computer Web site called a "blog". The word "blog" is a short way of saying Web log, or personal Web site. Anyone can start a blog, and they can write about anything they like. There are millions of blogs on the Internet today. They provide news, information and ideas in many people who read them. They contain links to other Web sites. And they provide a place for people to write about their ideas and react to the ideas of others. A research company called Perscus has studied more than 300 Web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year. However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products. At the same time, some long-standing blogs have ended last week, blogging leader Dave Winer closed his free blog service weblogs. com. He says the site became too costly to continue. He started the blog four years ago. And thousands of people had written on it. They are now upset because they did not know that the site was closing. One blog that is still going strong is called Rebecca's Pocket. Rebecca Blood created the Website in 1999. She wrote about the history of blogs on the site. That article led to a book called "The Weblog Handbook". It has been translated into four languages so far. Ms. Blood says Rebecca's Pocket gets about 30,000 visitors a month. She writes about anything and everything--politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from stealing money from on-line bank accounts. Question: Which of the following statements is NOT true according to the text? - Politicians don't use blogs at all - A lot of bloggers no longer write or read blogs - Those who like to use blogs are mostly teenage girls. - Dave Winer closed his "weblogs.com" because of money shortage.
Answer: Politicians don't use blogs at all

Question: Read the following article and select the best answer. Article: Plants are very important living things. Life could not go if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. So animals and man need plants in order to live. This is why we find that there are so many plants around us. If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and _ plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants don't grow from seeds. They grow from spores. Spores are so small and light that they can float in the air. We may say that spores are quite the same as the seeds. When these spores fall on wet and _ , they usually grow into new plants. Question: The main idea of the passage is that _ . - plants are important for life - plants cannot grow without air - there are many plants around us - we cannot live without water
Answer:
plants are important for life
