Article: One night in February 1962, John H. Glenn. Jr., flew over Australia. The man in the Mercury capsule was alone, but friendly voices reached him by radio. On the dark land 100 miles below, he saw a sprinkling of light. They marked the city of Perth, where people had turned on their lights as a greeting to him. In Friendship7, Glenn radioed, " The lights show up very well. Thank for everybody for turning them on." His capsule raced on to the east. During his three orbits(......) of the earth, Glenn could always reach one of eighteen tracking stations. Some of them were on ship at sea. Others were in the United States. Many of the stations had been built with the help of other countries. These countries allowed Americans to bring in radio equipment and set it up. Without the help of such lands as Nigeria , Zanzibar(,), and Mexico, there would have been breaks in the worldwide radio network. John H. Glenn. Jr., was the first America to orbit the earth. For his flight, the tracking network covered 60,000 route miles. Five hundred men worked in the stations along the route. Since his flight, the network has grown. Today, it covers more than 100,000 route miles and has about one hundred stations. One-third of these stations are outside of the United States. Question: Why did people in Perth turn on the lights? Yes or no, is the answer "They wanted to greet Glenn."?
(Answer)
No

Article: Many countries have passed safety laws that require seat belts in vehicles. A modern three-point seat belt, also called a safety belt, is a harness to prevent the driver or a passenger from flying forward and hitting hard against the interior of a vehicle during a collision. A modern seat belt will help to position you properly to gain maximum benefit from your car's airbags that will inflate during a collision. Using a seat belt also prevents you from being ejected from a car into the path of oncoming traffic. Research shows that when you wear a modern seat belt, you reduce the risk of death or serious injury by 70% or more during an auto accident. Seat belts have existed in different forms since the early days of automobiles, and they have changed from a single lap belt to the three-point seat belt we use today. In 1911 the first airplane seat belt was installed. Then, in the 1920's they were used in racecars. By the 1930s, a group of American physicians created lap belts for their own vehicles and urged vehicle manufacturers to provide seat belts on all vehicles. Dr. C. Hunter Shelden made a major contribution to our safety with his article in the November 5, 1955 Journal of the American Medical Association (JAMA). He strongly encouraged the manufacture and use of door locks, airbags, and retractable seat belts, like the ones we use today. The modern three-point seat belt, including a lap belt and a shoulder belt, was introduced as standard equipment on Volvo cars in 1959. In 1970, the state of Victoria in Australia made the wearing of a seat belt compulsory for every car driver and front-seat passenger. Today many countries have also mandated the use of five-point safety harnesses for carefully designed child safety seats that can protect a child during a serious car accident. An airbag is a Supplemental Restraint System, or SRS, and consists of a rapidly inflatable restraint cushion that works together with a seat belt to protect you during a collision. Modern cars often contain several airbags in... Question: We can learn from this article that _ . Yes or no, is the answer "American physicians created lap belts for their own vehicles because they had seen many injuries caused by car accidents"?
(Answer)
No

Article: Renata Di Pietro was studying to be an opera singer. But at 23, while on a music scholarship at the University of Iowa in 1976, her sight began to fail. Soon, it became increasingly difficult to read scores and pick up hand signals from conductors, and the gifted singer was forced to drop out. After moving to Cleveland, Georgia in 2005, Di Pietro relied on guide dogs to get around. Over the years, she became depressed when she'd lose one of the dogs, who had become her best friend, to old age or death. "It's very painful, because you love each one," she says. In 2009, Di Pietro was _ by information from a friend that miniature horses typically live for at least 30 years and make calm and strong guides. She started with a male horse, but he was too hard to control. Angel came next, a mini white female horse Di Pietro has mostly trained herself. "Horses have the ability to avoid the things in the way," she says. "If I am about to run into something, she slides her body in front of me." Di Pietro, now 59, has taught her guide horse to make some sounds with her hoof when she comes to stairs. "Angel can find a chair and locate the nearest door for me," Di Pietro says. Currently, she's training Angel to pull her wheelchair and to fetch. Despite her disability, Di Pietro still sings, performing with her husband, musician Carl Hummer, at special events. Angel is always by her side. "I fight a battle every day to take courage to engage the world," Di Pietro says. "Angel is my warhorse. We fight that battle together." Question: Why did Di Pietro have to give up her studying in the university? Yes or no, is the answer "She found it difficult to see things clearly."?

No
