Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Edmund Halley was an English scientist who lived over 200years ago. He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems. However, Halley had a friend named Isaac Newton. Who was a brilliant mathematician. Newton thought he had already which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse. Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientist. He made a surprising discovery. The comets that had appeared in the years 1531, 1607 and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart. This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again. It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley's prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet been called Halley's comet, in his honor. Question: Which of the following is TRUE? Options: A: Edmund Halley was an American scientist. B: Halley made his discovery by doing experiments. C: Isaac Newton was a famous mathematician. D: The orbit of a comet had the shape of an around.
Ans: C

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Two new whale sharks arrived at the world's largest aquarium on Friday. Both whale sharks, the world's largest fish, arrived at the Georgia Aquarium in Atlanta after 6 a.m. The pair had been flown 8,000 miles from Taipei, Taiwan. They will join the aquarium's three whale sharks--the only ones on display outside of Asia. " We re the only people in the world that can claim three times, " aquarium director Jeff Swanagan said, " Each time we learn more and more." The two young males were given Asian names. One is Taroko, named after Taroko Gorge, a national park in Taiwan. The other is Yushan, which means "Jade Mountain", and is named after a mountain in Taiwan. The sharks were flown from Taiwan on a plane in 20-foot-long tanks with oxygen machines and other equipment to keep the water suitable for them. They arrived at about 3:30 a.m. in Atlanta, where their tanks were moved to two trucks and driven to the aquarium surrounded by some of Atlanta police cars with their blue lights flashing. They were lowered into their new home--as Norton and two females, Alice and Trixie, circled nearby, seemingly curious about the new arrivals. It is difficult to tell the age of the whale sharks, but at least one of the new arrivals is believed to be the smallest the aquarium has got. They are believed to be the aquarium's youngest whale sharks yet. Question: The two new whale sharks _ Options: A: are the largest in America B: have Asian names C: have got used to living in America. D: arrived at the aquarium at 3:30 am
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Depression is a serious problem today.Depression causes workers to be unproductive,causing companies and countries to lose billions of dollars.One expert says that depression is like cancer because it is "widespread,costly and deadly".Depression hits one person in five around the world. Although people have believed depression to be a problem among the rich and educated,studies show that depression is a problem among everyone. Over any six-month period,between five to seven percent of the world's population will be suffering from a serious depression. suicide rates among people suffering from the disease in its extreme,or clinical form were 80 percent higher than in the population at large,and sufferers were four times more likely to have heart attacks. People who suffer from depression often have problems sleeping,getting up on time,and doing work productively. Depression,which researchers agree has its origin in the genes ,brings loss of confidence and ability to concentrate-making it impossible for employees and managers to work efficiently. Depression is made more serious in China by Chinese's inability to face it.Many people believe that depressed people are either weak or lazy. Besides,there is no good treatment,with few specialists available. "Most patients in China just don't get help,"a Chinese doctor says."In my hospital.I have to see 30 or 40 patients in a morning,just have time to say "Hello how do you feel?" In Western countries,people are not afraid to admit that they have depression,but most do not tell it to their boss,because they fear that their boss would fire them. "In my experience,aging bosses are the most willing to admit they have it. Because they feel the most secure about themselves,"an American doctor says. Hopefully,in the near future,people around the world will be able to admit that they have depression so that they can get the right treatment. Question: Which of the following is true according to the passage? Options: A: It is widely believed that everyone may suffer from depression. B: Depression brings great problems to its sufferers in their life and work C: Depression is a commonly-existing problem only in rich countries. D: The poorer and the less educated a person is,the less he will suffer from depression.
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: What is America's number one sport? Can I still say baseball? You could make that statement 30 years ago,but things have changed.Baseball of course has the richest history of all sports.But with the popularity of basketball and American football,there can now be an argument on which sport is American's number one sport. Basketball really took a turn in the1980's as Magic Johnson and Larry Bird took the NBA to another level.Of course,basketball was already popular and had seen such stars as Jerry West and Dr.J,but the real breakthrough came in the 1980's and from there it really took off with Michael Jordan into the 90's.Basketball has even become very global now as many NBA stars competed in the Olympics and faced no competition.Today,they had better be ready because there are so many talents in other countries and the competition will be stiff. Like basketball,American football has always been a favorite of many sports fans and its popularity has grown widely.The ratings that Super Bowl Sunday brings are amazing.They have even talked about making Super Bowl Sunday a national holiday. In the year 2050,basketball and American football will have history like baseball's rich history and maybe American national sport.They have been trying for years,but it is not going to happen. So what is American's number one sport? To me baseball will always be Americans' hobby--rich in history and many memories for people of all ages.If you have any comments on this subject,do give your opinions. Question: The most powerful basketball player in l980's is Options: A: Larry Bird B: Michael Jordan C: Jerry West D: Magic Johnson
Ans:
B
