Today, we take you to the United States National Arboretum, an active center for both scientific research and public education. Many people who come to Washington are astonished when they first visit the National Arboretum. The Arboretum is only a short drive from the center of the city. However, visitors often feel like they are remote from the busy American capital. The Arboretum covers one hundred eighty hectares of green space in the northeast part of Washington. The area is famous for its beautiful flowers, tall trees and other plants. About nine thousand different kinds of plants grow there. The National Arboretum was established by an act of Congress in 1927. Today, the United States Department of Agriculture's Agricultural Research Service operates the Arboretum. The goal of the Arboretum is to carry out studies and provide education in an effort to improve the environment. The goal includes protecting trees, flowers and other plants and showing them to the public. The National Arboretum is a popular stop for visitors to Washington. It is open every day of the year except December twenty-fifth, the Christmas holiday. Money is not necessary to visit the Arboretum. As many as six hundred thousand people visit the Arboretum's grounds each year. Hundreds of thousands of people also visit with the help of computers. They use the Arboretum's Internet web site to learn about current research programmes and how to care for plants. Director Thomas Elias says Arboretum officials would like to see even more visitors. He says they believe that many people do not know it exists. Part of the problem might result from the fact that the Arboretum is about five kilometers from the closest train station. Many famous places in Washington are a short walk from Metrorail, the local train system. The Arboretum is easy to reach by automobile or bus,...

Write a multi-choice question for the following article, with the given choices and answer: Article: Robinson Crusoe is a famous novel written by Daniel Defoe. The book tells the story of a man who is shipwrecked . He spends 28 years on an island near Venezuela. The book tells the story of everything that happens to Robinson Crusoe. He hopes someone will rescue him, but he has been there for so long on his own that he also begins to fear being rescued. Robinson Crusoe was published in 1719. Most experts believe the story is based on the life of Alexander Selkirk, who was a Scottish sailor. On an expedition in 1704, Selkirk had an argument with his ship's captain. Selkirk thought the ship was not safe and was about to fall apart. When the ship stopped at a remote island to get fresh water, Selkirk got off. He tried to get the other crew members to leave with him, but nobody would. The shop then sailed away without him. Selkirk spent four years and four months on his own on the island, known as Aguas Buenas. Selkirk was finally rescued by a ship that visited the island in 1709. The ship's captain was grateful to Selkirk because he provided food for the crew when they arrived. Now archaeologists think they have found the remains of Selkirk's camp on Aguas Buenas. They found two deep holes that would have held wooden posts. The archaeologists say this is evidence that Selkirk built a shelter there. The post holes are near a fresh water stream. They are located quite high up, which would have meant that Selkirk was able to watch out for the ships coming close to the island. The most interesting evidence, the archaeologists say, is part of a piece of equipment used by sailors to navigate . Historians believe Selkirk was a navigator, so the instrument could have belonged to him. Robinson Crusoe was published ten years after Selkirk was rescued. Most experts think Daniel Defoe heard and read stories about Selkirk, which inspired him to write the book. Options: A lost its way while sailing B lacked fresh water upon arrival C was being navigated by Selkirk D was running out of food upon arrival Answer: D was running out of food upon arrival Question:
Ans: We can infer from the text that the ship that visited Aguas Buenas in 1709 _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: The main cause of a heart attack is not exercise or stress -- it's air pollution, according to a study published in The Lancetthis month. Researchers found spending time in traffic, whether as a driver or a pedestrian , tops the list of risk factors that bring on a heart attack. Jon Ayres, professor of environmental and respiratory medicine at the University of Birmingham, says, "Air pollution is not only linked to strokes, heart attacks and cancer -- it has a deep effect on those with existing respiratory conditions." So how can you avoid the damage? We asked the experts for their tips. TAKE TO THE SIDE STREETS Avoid main roads. These have the highest number of vehicles and also more traffic jams, which tend to run on diesel . Diesel engines emit tiny particles that reach the lungs most easily. Choose side streets, pavements, parks and avenues lined with trees. BUY SOME HOUSEPLANTS We spend 90 percent of our time inside, but studies by the U.S. Environmental Protection Agency have found that pollution levels can be two to five times higher indoors than outside. Objects such as synthetic carpets, TV screens can emit chemicals called volatile organic compounds (VOC,), which have been linked to diseases such as cancer. Researchers at Curtin University in Perth, Australia, found an increase in asthma risk among children under three who had high VOC levels in their homes. Therefore, the application of air fresheners and houseplants can keep the circulation of the air and absorb the pollutants. Options: A Tips to avoid the damage of air pollution. B Air pollution is the main cause of a heart attack. C Air pollution is linked to strokes, heart attacks and cancer. D Pollution levels can be two to five times higher indoors than outside. Answer: A Tips to avoid the damage of air pollution. Question:
Ans: What is the passage mainly about?
