One of the most recent social changes taking place in the world is social networking. Social networking has been in existence for at least 150 years, and probably longer than that. In the times before the invention of the computer and the World Wide Web (WWW), social networking was done in person. People who had similar likes and interests would gather together to share experiences, make new friends, and improve their businesses. On the Internet, social networking websites made their first appearances during the late 1990s. The first major social networking website in the United States was MySpace. MySpace allowed its users to exchange messages, share pictures, and make new friends in a way that was never thought of in the past. With MySpace, people who did not go out much could reach out to others from their own homes. In 2004, Facebook was created. It was first a website created for use by Harvard University's students and teachers, but it soon expanded to include just about everyone. It is now larger than some of the largest companies in the world. It is a website that is changing all the time. Facebook has completely changed the way people stay connected with each other and the rest of the world. The way it works is simple. Users can set up a new account   easily. All a new user needs is an email address to start. Once a person has created an account and his friend also has his own Facebook page, he can invite his friend by sending a request out to him. Once you get started, making new friends will come easily. What do new users of Facebook need to create an account? A) An email address. B) His friend's help. C) High-speed network. D) His friend's Facebook page.

Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them. More than that, though, he has also interfered   with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man's interference can be seen in what happened many years ago in the forest of the Kaibab plateau   of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead. The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and _ . In 1882 a visitor noted, "We, who ... have wandered through its forests and parks, have come to regard it as the most enchanting region it has ever been our privilege   to visit." This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly. Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer's enemies. In 25 years' time, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000. The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd  ,but a far greater loss resulted from starvation   and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000. The number of the deer in the Kaibab had increased enormously in  _  years' time. A) 25 B) 6 C) 12 D) 18
