Read the following article and select the best answer. Article: They are the sort of friends who are so close they trust each other with their lives. If one falls, the other is there to catch him. They are Wellman, whose legs were permanently injured nine years ago in a rock-climbing accident, and Corbett, an experienced rock climber. Together, they climbed up Half Dome, the famous 2,000-foot rock in the Yosemite National Park, through one of the most difficult routes . During the climb, Corbett took the lead, hit in the metal spikes that guided the ropes and climbed up. Then, after Wellman pulled himself up the rope, Corbett went down to remove the spikes and climbed up again. This process was repeated time and again, inch by inch, for 13 days. Wellman's job was not easy either. He got himself up the rope through upper body strength alone. In all, Wellman figured that he had done 5,000 pull-ups up the rope on the climb. However, when the two men first met, they never talked about climbing. "He knew that was how I got injured." Wellman said. Until one day Wellman decided that he wanted to climb again and they started training. Their climb of Half Dome was not all smooth. At one point, pieces of rock gave way, and Corbett dropped down quickly. Wellman locked their rope in place, stopping the fall at 20 feet. His quick action probably saved his friend's life. "Your partner can save your life -- you can save your partner's life," Wellman said as the pair received congratulations from friends. "There are real close ties." Question: Why did the two men never talk about climbing when they first met? - Corbett was poorly trained. - Wellman had lost interest in climbing. - Corbett didn't want to hurt Wellman. - Wellman hadn't decided whether to climb again.
Corbett didn't want to hurt Wellman.

Read the following article and select the best answer. Article: Investors soon will be able to own shares of Facebook stock. The world's biggest social media network presented documents to the Securities and Exchange Commission on Wednesday. The documents are required before the company can make its initial public offering or IPO. A date for the stock sale has yet to be announced. Experts say Facebook could raise about five billion dollars. That would be one of the biggest IPO sales ever. And it would be much bigger than Google's first public stock sale in 2004. At that time, the Internet search company raised almost two billion dollars. Facebook has 800 million users around the world. It is the second most visited website after Google. Now, experts say the social media network is in a position to become one of the most valuable Internet companies. Stock expert Anupam Palit at Greencrest Capital says that among social media sites, Facebook is in a class by itself. "It is the biggest company in this space and we believe what makes it very unique from every other company that went public last year in this space is that it is very, very profitable." said Anupam Palit. Early estimates place the total value of the social network between 75 and 100 billion dollars. That includes earlier investments by other companies. David Kirkpatrick wrote the book The Facebook Effect. He says Facebook's IPO will be historic. The stock sale could also make Facebook founder Mark Zuckerberg one of the world's youngest billionaires. He is only 27. Investment companies are likely to buy Facebook stock first. But investment manager Jim O'Shaugnessy says that is not so bad. He says the prices of some IPO stocks are too high and fall not long after they first go on sale. Recently, share prices of some Internet businesses have fallen after their stocks were first offered. For example, stocks of Linkedln, Groupon and Zynga, dropped in price by as much as 25% after going public. There were similar questions eight years ago when Google first sold stock to the public. Today, Google is one of the world's... Question: Which would be the best title for this passage? - Facebook and Its IPO - The Difference Between Facebook and Google - The Founder of Facebook - A Book Called The Facebook Effect
(Answer)
Facebook and Its IPO

Ques: Read the following article and select the best answer. Article: Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived . Biological death occurs when changes in the organism lead to the "breaking up" of vital cells and tissues. Death is then unchangeable and final. Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism , cooling delays the processes leading to biological death. To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta's heart became active once more. After fifteen minutes, spontaneous breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal. Question: For a person who suffers from the clinical death - his most important organs are damaged. - he still has the possibility of getting back to life. - he can not avoid final death. - he is still very much alive
Ans: he still has the possibility of getting back to life.
