What is the expectation of the scientists by designing the collider? To translate data as electronic code. To identify new atomic particles. To discover new clues to the origin of the universe To accelerate beams of protons. 53. According to the passage, the collider might become out-of-date . due to its high cost before it is ever built because of budget cuts owing to the limited advanced equipment 54. Judging from the passage, the collider is worth its high cost has proved to be very useful will make many people jobless is not yet operating 55. What is the main topic of this passage? The basic structure of matter. Design of the super collider Construction of a tunnel. Detecting the size of the universe. Passage Two What makes a person a scientist? Does he have ways -or tools-of leering that are different from others? The answers are no .It is not the tools a scientist uses but how he uses these tools that make him a scientist. You will probably agree that knowing how to use a power saw is important to a carpenter .You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone .The scientist, however, goes one step further: he must be sure that he has a reasonable answer to his question and that his answers can be confirmed by other person .He also works to fit the answers he gets to many questions into a large set of ideas about how the world works. The scientist’s knowledge must be exact. There is no room for half right or just half the time .He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at the times .If the conditions are different, any changes the scientist observes in a demonstration must be explained by changes in the conditions .This is one reason that investigations are important in science .Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested though investigation. Einstein’s ideas were shown to be correct. A scientist uses many tools for measurement. Then the measurements are used to make mathematical calculations that may test his investigations. 56. What, according to the passage, makes a scientist? A) The tools he uses B) His ways of leering C) The way he uses his toes D) The various tools
