Article: Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. These mountains are a splendid sight when viewed from the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure( )that must be maintained. Unfortunately, these systems are starting to break down. It is not just in Yosemite but in national parks around the nation. Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with. Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park Service had to send water trucks to provide water for the visitors. Last month pipe almost broke again and roads had to be closed for a while. Why hasn't the National Park Service kept up the park repairs? There is lack of money. The United States has 378 mountains, parks, and wilderness areas. Between three and four billion dollars are needed for repairs. Yosemite is one national park that does have money fro repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park. A Sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowed park. Question: The main problem of Yosemite Park is its _ . Yes or no, is the answer "overcrowdedness"?
No

Article: The area south of the Thames at Greenwich has a long history. Throughout time different buildings have been constructed on the same site. The Palace of Placentia, an English Royal Palace built in 1447, no longer exists apart from a few remains under the present buildings. The grand buildings on the South Bank of the Thames at Greenwich were designed by Sir Christopher Wren, most famous for St. Paul's Cathedral. The buildings were finally completed in 1745, although some parts started to be used as early as 1705. They're now part of a university -- having served as a naval hospital and a naval college and the setting for several cinemas. But the buildings stand on a site which has a much longer history, of which now only a part remains that is below the ground. For nearly two hundred years, from around 1450 to 1650, Greenwich was one of the main royal palaces of England. Some of the most famous English rulers, such as Henry VIII and Elizabeth I, not only lived there, but also were born there. Henry VIII put an armory there, and there were also gardens, a great fountain and a mass of buildings. The Palace was also in a strategic location, because at the time either side of Greenwich on the Thames were important Royal Dockyards . Eventually, though, the Palace fell into disrepair. In 1664, the King at the time, Charles II, decided to replace it with completely new buildings in a modern style. Only a cellar from the former Royal Palace now remains, under one of the new buildings. Its red brick, typical of the 16th century, contrasts sharply with the white stone above it.

Article: A company advertised in the newspaper for a sales position. Details of the prerequisite , salary and benefits were given. It was also clearly stated that applicants needed to take an aptitude test and an interview. However, looking at the whole advertisement, one could not find any contact information of the company. Most interested applicants thought that it was the company's HR department's carelessness or a printing error. They therefore waited patiently for the newspaper to publish an amendment. But instead of waiting for the newspaper to publish the company details, another three applicants took the initiative to find out the company's contact information themselves. Tim did a search on the Internet. By typing the company's name, he easily obtained all the information including its contact number. Lisa called up the local telephone number search service and found out the company's office number. She called up the office and got the required contact information. Donna put in a greater effort in her search. She remembered seeing a poster by the same company in the city so she drove all the way down and made a few rounds to search for it. She finally found it together with the company's contact information. Three days after that advertisement was published in the newspaper, most interested applicants were still waiting eagerly for an amendment. On the other hand, the application letters and resumes of Tim, Lisa and Donna had already reached the hands of the company's HR manager. They were then called up for an interview. During the interview, all went well and immediately they were hired. The three of them were a little surprised at how fast things went on. They were expecting for an aptitude test as stated in the advertisement. The HR director answered them, smiling, "Our test is hidden in the advertisement itself. To be a good salesperson in this age, he or she has to be broad-minded and very importantly, does not follow rigid steps or rules. You are all clever and agile. In a short time, you've...
