Article: About ten men in every hundred suffer from color1 blindness in some way. Women are luckier, only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman! There are different forms of color1 blindness. In some cases a man can not see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed. Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called "cones". These help us to see in a bright light and to tell difference between color1s. There are also millions of "rods" but these are used for seeing when it is nearly dark. They show us shape but no color1. Some insects have favorite color1s. Mosquitoes like blue but do not like yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite color1s. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful color1s by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible color1s around. Question: This passage is mainly about _ . Yes or no, is the answer "color1 blindness"?
No

Q: Article: I entered high school having read hundreds of books. But I was not a good reader. Merely bookish, I lacked a point of view when I read. Rather, I read in order to get a point of view. I searched books for good expressions and sayings, pieces of information, ideas, themes--anything to enrich my thought and make me feel educated. When one of my teachers suggested to his sleepy tenth-grade English class that a person could not have a "complicated idea" until he had read at least two thousand books, I heard the words without recognizing either its irony or its very complicated truth. I merely determined to make a list of all the books I had ever read. Strict with myself, I included only once a title I might have read several times.(How, after all, could one read a book more than once?)And I included only those books over a hundred pages in length.(Could anything shorter be a book?) There was yet another high school list I made. One day I came across a newspaper article about an English professor at a nearby state college. The article had a list of the "hundred most important books of Western Civilization." "More than anything else in my life," the professor told the reporter with finality(firmly), "these books have made me all that I am." That was the kind of words I couldn't ignore. I kept the list for the several months it took me to read all of the titles. Most books, of course, I hardly understood. While reading Plato's The Republic, for example, I needed to keep looking at the introduction of the book to remind myself what the text was about. However, with the special patience and superstition of a schoolboy, I looked at every word of the text. And by the time I reached the last word, pleased, I persuaded myself that I had read The Republic, and seriously crossed Plato off my list Question: On hearing the teacher's suggestion of reading, the writer thought _ . Yes or no, is the answer "one must read as many books as possible"?
A: Yes

Question: Article: Crowd controls could soon become an important skill for climbers on Mount Everest, as important as physical strength or watching the weather. In a single day last week, nearly 40 people reached the top of the world --- a record. Reports from base camp spoke of queues at dangerous ridges and crowds as people passed each other in the final dash for the 8, 848 meters top. More traditional mountaineers tease about the circus atmosphere surrounding Everest in recent years, and there are warnings that the crowds are making the mountain more dangerous. In 1996, 14 died on the mountain when the members of several groups were trapped at high altitudes by sudden snowstorms. Bad weather in early May led to this year's jam on the summit ridge, but the loss, luckily, was light. Just four climbers died, including a Nepali Sherpa who had made 11 previous successful climbing. Traditionalists are also worried about the growing tendency of climbers to set records and achieve "firsts", rather than simply climb the mountain. This year's crop of mountaineers included the oldest man, 64-year-old Sherman Bull from Connecticut, and the youngest, 16-year-old Temba Tsheri Sherpa of Nepal. An American with only one arm was on the mountain this year; an Indian with no legs also tried but failed. Erik Weihennieyer, an American, became the first blind person to reach the top of the world. His fellow climbers stayed in front of him on the way up, describing the type of land and ringing bells. Nepal views Mount Everest as something of a cash cow. The government charges journeys a minimum of $ 70,000. That is probably why officials in Katmandu are ignoring concerns about overcrowding and talking about even more climbers coming next year. But a celebration of the 48th anniversary of the first conquest of Everest, by Sir Edmund Hillary and Sherpa Tenzing Norgay, was cancelled after violent strikes. Tumultuous Nepali politics, it seems, could be just the crowd-control measure that Everest needs. Question: What is the problem that the climbers have to face in recent years? Yes or no, is the answer "Overcrowding."?
Answer: No

Article: It helps us understand the world better if we know a little geography and have some maps at hand. But with maps in Chinese only, misunderstanding is possible in studying world events. Chinese names are long, hard to pronounce and without meaning to a foreigner. For the opening of the country maps are important and helpful and needed badly. I wish maps various languages, such as those used in the United Nations, would come out and be sold in all bookstores open to Chinese. Question: In the United Nations people use maps in _ . Yes or no, is the answer "various languages"?
**Answer**
No
