I'm taking a test and have to guess the right answer to the question after the article. Article: There are many people who say Thomas Edison invented the twentieth century. Although there are those who may disagree, yet Edison was one of the greatest inventors in America. Born in 1847 in Ohio, Thomas Edison attended school for only three months. After his teacher said that he could not learn, Edison's mother decided to teach him at home. There he was allowed to study the subjects that most interested him. By age ten, Edison had built a science laboratory of his own. Edison got his first job at age twelve on the railway selling candy and newspapers. There he once saved a boy whose father was the boss of the railway station. In return the boss helped him a lot. In his late twenties, Edison built an "invention factory" where he and his business partners could devote all their time to inventing. After improving upon the telephone, Edison created the phonograph . Although Edison did not actually invent the light bulb, he did create an electric lighting system which led to its widespread use. Edison set up the first central electric power station in 1882, so New York became the first city in the world to have electric lights. This was the beginning of the modern world in which electricity became a way of life. The following year, one of Edison's engineers discovered electrons , which at last led to electronics. Without electronics, we might not have radio, TV, computers, or space travel. The rest of Edison's life was spent making and improving inventions. Thomas Edison died at the age of eighty-four in 1931. Three days later, much of America dimmed its lights in honor of the inventor--a man who had more impact on the development of present-day civilization than anyone else in history. Question: The best title for this passage is _ . Options: A: Edison, a Poor Man B: Edison, a Great Inventor C: Edison Died at 84 D: Edison and His Childhood

I'm taking a test and have to guess the right answer to the question after the article. Article: Life has changed in Mexico City. Streets normally filled with people are empty. One of the most popular professional soccer teams recently played a game in an empty stadium that can seat more than100,000 people. It's swine flu that has made life in Mexico City grind to a halt . Seemingly out of nowhere, swine flu has caused confirmed deaths in 12 countries as of April 30. It has sent a wave of alarm around the world. Governments are trying to find ways to prevent further out-breaks. The World Health Organization has raised its swine flu global threat level to five out of six. People may be familiar with bird flu, but they know little about swine flu. Swine flu is a contagious respiratory disease in pigs. It is caused by a type-A influenza virus. Humans can also catch swine flu. The virus causes regular outbreaks in pigs, but people usually do not catch it. However, there have been cases of the virus spreading to people, and then from one person to another. The symptoms of swine flu are similar to the common flu. They include fever, lethargy , lack of appetite, coughing, runny nose, sore throat, nausea , and vomiting . The high proportion of young adults among the deaths is one of several mysteries about this virus. Most of the dead had lung damage. What caused it is not yet known. The virus spreads the same way the common flu does. When an infected person coughs or sneezes around another person, the latter is put at risk. People can get the disease by touching something with the flu virus on it and then touching their mouth, nose or eyes. There are medicines to treat swine flu. Doctors suggest using anti - viral drugs. They keep the virus from reproducing inside the body. Although there are no vaccines for it now, several everyday steps can help prevent the spread of the virus: washing hands frequently; avoiding close contact with people who are sick; and avoiding touching surfaces that might have the virus on it. People may worry that they will get swine flu from eating or preparing pork. In fact,... Question: What can we infer from the passage? Options: A: At present there still aren't effective vaccines for swine flu. B: Swine flu virus cannot spread in the air. C: From now on, people can't eat pork if they want to be safe. D: All of the dead killed by swine flu had lung damage.

I'm taking a test and have to guess the right answer to the question after the article. Article: Lichens are difficult to see. They don't move. They often mix into the living place. You might not even recognize one if you are looking right at it. Lichens live on rocks, branches, houses, and even metal street signs. You can find these colorful organisms almost everywhere -- from deserts to rainforests, and from Antarctica to Africa. They've traveled in outer space, and some scientists think there might even be lichens on Mars. What you probably don't realize is that a lichen is more than a single thing. It includes two different types of living organisms: a fungus and an alga . Neither of these organisms is a plant, so the lichen isn't a plant either. Through photosynthesis , the alga gets the sun's energy to make food for the fungus, which is the place for the alga to live in. However, the alga cannot leave the fungus. Around the world, scientists have found tens of thousands of types of lichens. Many may not even have been discovered yet. As scientists continue to find new kinds of lichens, they are also working to understand how they are connected to one another. By putting together a lichen family tree, they hope to understand why so many different types of lichens have grown in so many places around the world. Many researchers are trying to understand basic facts about the organisms and their connections. Researchers are also using lichens to examine the health of the environment. Question: What do we know about lichens according to the passage? Options: A: They will die if they leave Earth. B: There are more lichens than plants on Earth. C: They look similar to the environment around them. D: They are too small to be easily seen by people.
