Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.     It is estimated that over 99 percent of all species that ever existed have become extinct. What causes extinction? When a species is no longer adapted to a changed environment, it may perish. The exact causes of a species’ death vary from situation to situation. Rapid ecological change may render an environment hostile to a species. For example, temperatures may change and a species may not be able to adapt. Food Resources may be affected by environmental changes, which will then cause problems for a species requiring these resources. Other species may become better adapted to an environment, resulting in competition and, ultimately, in the death of a species.    The fossil record reveals that extinction has occurred throughout the history of Earth. Recent analyses have also revealed that on some occasions many species became extinct at the same time – a mass extinction. One of the best-known examples of mass extinction occurred 65 million years ago with the demise of dinosaurs and many other forms of life. Perhaps the largest mass extinction was the one that occurred 225 million years ago. When approximately 95 percent of all species died, mass extinctions can be caused by a relatively rapid change in the environment and can be worsened by the close interrelationship of many species. If, for example, something were to happen to destroy much of the plankton in the oceans, then the oxygen content of Earth would drop, affection even organisms not living in the oceans. Such a change would probably lead to a mass extinction.           One interesting, and controversial, finding is that extinctions during the past 250 million years have tended to be more intense every 26 million years. This periodic extinction might be due to intersection of the Earth’s orbit with a cloud of comets, but this theory is purely speculative. Some researchers have also speculated that extinction may often be random. That is, certain species may be eliminated and others may survive for no particular reason. A species’ survival may have nothing to do with its ability or inability to adapt. If so, some of evolutionary history may reflect a sequence of essentially random eventsWhat does the author say in paragraph 1 regarding most species in Earth’s history?

Read the following passage and mark the letter A, B, C or D on your answer sheet to choose the best answer for each of the question from 43- 50 American movies create myths about college life in the United States. These stories are entertaining, but they are not true. You have to look beyond Hollywood movies to understand what college is really like.Thanks to the movies, many people believe that college students party and socialize more than they study. Movies almost never show students working hard in class or in the library. Instead, movies show them eating, talking, hanging out, or dancing to loud music at wild parties. While it is true that American students have the freedom to participate in activities, they also have academic responsibilities. In order to succeed, they have to attend classes and study hard. Another movie myth is that athletics is the only important extracurricular activity. In fact, there is a wide variety of nonacademic activities on campus such as special clubs, service organizations, art, and theater programs. This variety allows students to choose what interests them. Even more important, after graduation, students’ résumés look better to employers if they list a few extracurricular activities.Most students in the movies can easily afford higher education. If only this were true! While it is true that some American college students are wealthy, most are from families with moderate incomes. Up to 80% of them get some type of financial aid. Students from middle and lower-income families often work part-time throughout their college years. There is one thing that many college students have in common, but it is not something you will see in the movies. They have parents who think higher education is a priority, a necessary and important part of their children's lives.Movies about college life usually have characters that are extreme in some way: super athletic, super intelligent, super wealthy, super glamorous, etc. Movies use these stereotypes, along with other myths of romance and adventure because audiences like going to movies that include these elements. Of course, real college students are not like movie characters at all.So the next time you want a taste of the college experience, do not go to the movies. Look at some college websites or brochures instead. Take a walk around your local college campus. Visit a few classes. True, you may not be able to see the same people or exciting action you will see in the movies, but you can be sure that there are plenty of academic adventures going on all around you!Which of the following could best serve as the title of the passage?

Read the following passage and mark the letter A, B, C or D on your answer sheet to choose the best answer for each of the question from 43- 50 American movies create myths about college life in the United States. These stories are entertaining, but they are not true. You have to look beyond Hollywood movies to understand what college is really like.Thanks to the movies, many people believe that college students party and socialize more than they study. Movies almost never show students working hard in class or in the library. Instead, movies show them eating, talking, hanging out, or dancing to loud music at wild parties. While it is true that American students have the freedom to participate in activities, they also have academic responsibilities. In order to succeed, they have to attend classes and study hard. Another movie myth is that athletics is the only important extracurricular activity. In fact, there is a wide variety of nonacademic activities on campus such as special clubs, service organizations, art, and theater programs. This variety allows students to choose what interests them. Even more important, after graduation, students’ résumés look better to employers if they list a few extracurricular activities.Most students in the movies can easily afford higher education. If only this were true! While it is true that some American college students are wealthy, most are from families with moderate incomes. Up to 80% of them get some type of financial aid. Students from middle and lower-income families often work part-time throughout their college years. There is one thing that many college students have in common, but it is not something you will see in the movies. They have parents who think higher education is a priority, a necessary and important part of their children's lives.Movies about college life usually have characters that are extreme in some way: super athletic, super intelligent, super wealthy, super glamorous, etc. Movies use these stereotypes, along with other myths of romance and adventure because audiences like going to movies that include these elements. Of course, real college students are not like movie characters at all.So the next time you want a taste of the college experience, do not go to the movies. Look at some college websites or brochures instead. Take a walk around your local college campus. Visit a few classes. True, you may not be able to see the same people or exciting action you will see in the movies, but you can be sure that there are plenty of academic adventures going on all around you!American parents believe in ______.
