Input: Consider Input: Article: The college entrance exam is not only a big challenge for Chinese high school students, but also a very important exam in the lives of South Korean students. Although the long, cold winter has already started in South Korea, the annual national exams have made the atmosphere very heated. More than 675,000 South Korean high school graduates took the college entrance exam last Wednesday. They usually take exams in Korean, maths, sociology , history and foreign languages. Officially there is one college place for every 1.33 students. But because all the students want to go to the top universities in the country, the competition can reach one place for 10 students. The students want to attend these colleges for both their famous names and better job opportunities. Because students face fierce competition, they have to study very hard to realize their dreams. Park Seung said he and his classmates often go to school before 7:30 a.m. After school has finished at 6:30 p.m., most of them go to the library to continue their study instead of returning home. Since many libraries in South Korea are open 24 hours a day, they often stay long into the night. Many of the Senior 3 students only sleep for three to four hours a day. "I feel a lot of pressure, but I have to study very hard in order to make my dream come true. This is my lifetime goal and it will be a turning point in my life which could decide my future," Park said. The exam day is a very serious day for the whole of South Korea. Vehicles are not allowed within a 200-metre radius of all the test sites to make sure the students have quiet surroundings. Tooting of horns is forbidden, even airplanes are ordered to avoid landing and take-off near the test sites during listening comprehension test hours. Students are told their scores in December before they apply for college. This is followed by face-to-face oral tests. There are public and private universities in South Korea. Many private universities are well-known, but their fees can be 18, 000 yuan each term. This has made a lot of students think again.

(C) Many of the Senior 3 students can't have enough sleep. (D) Airplanes are ordered to avoid landing and take-off during national exams.
Asnwer: B

Input: Consider Input: Article: Ban Fur? Then Why Not Leather? Much to the displeasure of some local businesses, the City Council in West Hollywood, California, voted without opposition last week to ban the sale of fur products. Should laws be involved in this issue? Is it unfair to ban sales of fur, but not sales of leather and hides ? Animals Do Not Have Rights By Tibor R. Machan My view is that animals do not have basic rights. It is a matter of ethics and not of the laws of human societies. If animals had such rights as human beings do, they would have to be held responsible for killing fellow animals in the wild. That way of thinking about animals makes a category mistake. Using animals, including their fur or organs, to improve people's lives is acceptable. A Small Step Against Cruelty By Kate Carter Both fur and leather are the skins of dead animals. Why should we think that the lovable furry ones deserve more of a life than the less pleasing ones? Some say leather is less cruel because it's a byproduct of the meat industry. But this isn't really true. Some cheap leather may be a byproduct of the meat industry, but often it's the other way round. In South Africa, where there is a developing market for ostrich farms, the skins account for roughly 80 percent of the slaughtered birds' value, a mere 20 percent of which comes from the meat. "Who" Are You Wearing? By Marc Bekoff West Hollywood's ban is a move in the right direction. However, we must work to ban the sales of leather and hides, too. Furs come from animals who are attacked to become clothing, while some leather and hides come from slaughterhouse animals. We must remember that when people choose to wear fur, leather and hides, they are wearing formering conscious beings. So it's a matter of who they are wearing, not what they are wearing because these animals must be referred to as who and not what or that.
Question: What is the passage mainly about?
Options: (A) West Hollywood's ban on fur products. (B) Differences between fur and leather sales. (C) The government's role in protecting animals. (D) The ecological imbalance in West Hollywood.
Asnwer: B

Output: No

Input: Consider Input: Article: Edmund Halley was an English scientist who lived over 200 years 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 worked out that problem, but he could not find the papers on 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 scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance 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 to make a prediction of what would happen in the future. He decided that this 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 had been called Halley's comet, in his honor.
