Article: The need to feed a growing population is putting much pressure on the world's supply of water. With 97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage seems strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural industries experience constant water shortages. Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements. This is particularly troubling for countries with agricultural industries in areas dependent on irrigation . In Texas, farmers' overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed. Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry. Question: Which of the following is TRUE? Yes or no, is the answer "The underground water in Saudi Arabia might run out in 50 years."?
No

Article: So far, educationists have still failed to design anything more efficient and reliable than examinations. Some people say examinations test what you know. 71 . They may be a good means of testing memory, or the skills of working rapidly under extreme pressure, but they can tell you nothing about a person's true ability and talent. Question: Educationists, of course, should take the responsibility to face the challenge and come up with wise solutions. Yes or no, is the answer "The answer is ly yes."?
No

Q: Article: What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science? We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work. What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves. He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum . He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively. Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation. Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place. These seem to be some of the ways in which a successful... Question: Many people believe that science helps society to progress through _ Yes or no, is the answer "more than one aspect."?
A: Yes

Question: Article: Long ago there lived a powerful king. Some of his ideas were good, but others caused people to suffer. One of the king's ideas was to set up a public arena . When a person was accused of a crime, his future would be decided in this arena. It had two doors, side by side, exactly alike. The accused person was taken into the arena and asked to open one. Behind one door was a hungry tiger, while behind the other was a lady chosen especially for him. To this lady he would be immediately married, in honor of his innocence. The king had a beautiful daughter whom he loved very much , and she secretly loved a young commoner . When the king discovered their relationship, the man was immediately put in prison, and a day was set for him to enter the arena. The princess knew behind which door stood the tiger, and behind which a lady. She also knew that the lady was one of the loveliest in the kingdom. The princess hated the woman behind that silent door. As he entered the arena and his eyes met the princess's, the young man knew that she knew behind which door waited the tiger, and behind which stood the lady. The princess raised her hand, and made a short, quick movement toward the right. No one but her lover saw it. Every eye was fixed on him. He turned, and with a firm, quick step he walked across the empty space to the door on the right and opened it. Now, the point of the story is this: Did the tiger come out of that door, or did the lady? The more we think about this question, the harder it is to answer. It involves a study of the human heart. The soul of the princess loved the young man but also burned under the fires of sadness and jealousy . The question of her decision cannot be easily answered. And so I leave it with all of you: which came out of the open door? The lady or the tiger? Question: Which of the following is TRUE about the princess's decision? Yes or no, is the answer "The question of it is left open by the author."?
Answer: Yes
