89 . Nine years ago, a rice paddy in eastern Java suddenly began spewing mud. Before long, it covered three square miles; roads factories and homes disappeared under a tide of muck. Twenty lives were lost and nearly 40,000 people displaced, with damages topping $ 2.7 billion. The disaster, known as the Lusi mudflow, continues to have its impact till now. A mud volcano, Lusi expels water and clay rather than molten rock. such eruptions occur around the world, but Lusi is the biggest and most damaging know. Scientists have debated the cause for years. and two intensely argued hypotheses have emerged: Some believe and earthquake set off the disaster, others that the mudflow was caused by a company drilling for natural gas. Researchers largely relied on computer models and comparisons with other earthquakes and mud volcano eruptions. But recently scientists uncovered a previously overlooked set of gas, reading collected at the drilling sites by Lapindo BBrantas, a natural gas and oil company, in the days before the mudflow began. In a report in, the new data proves that the drilling by the company caused the disaster. The passage is about _______
- A. Indonesia's nine-year-old volcano's eruption
- B. Mud versus usual volcanoes in science
- C. Indonesia's mud volcano and its causes
- D. Why Indonesia's dormant volcano became active

By culture, (L3) one means first of all what the anthropologists mean, the way of life of a particular people (L4) living together in one place. That culture is made visible in their arts, in their social system, in (L5) their habits and customs, in their religion. It is and aggregate of customsinstitutions, manners, (L6) standards, testes, morals and beliefs. Now, these are transmitted rather by the family than by (L7) the school , hence when family life fails to play is part, we must expect our culture to (L8) deteriorate (L9) It is a delusion to think that the maladies of the modern world can be put right by a system of (L10) instruction. on the contrary, universal education, by lowering standards, morals and tastes to (L11) a common denominator and by sharpening the wits rather than disciplining character, tends to (L12) break down existing cheeks and balances. Education should be the drawing forth of potential (L13) values, it should not be the destruction of the safeguards that tradition place around young (L14) egos naturally inclined to wilful and precarious flights. (L15) 1.The writer uses the term ‘culture’ to refer to-
- A. the cultivation of a plant or garden by a community
- B. one's acquaintance with literature and art

269 . The First Amendment to the American Constitution declares o freedom of the press to all people. Although this right was not officially adopted until 179 l , the famous Zenger trial of 1735 laid the groundwork for insuring this precious freedom. .73 John Peter Zenger emigrated as a teenager from Germany. In 1733, he began publishing the New York Weekly journal. The o following year, he was arrested for writing a story about the crown-appointed governor of New York. While Zenger was imprisoned for nine months, his wife dutifully published the newspaper 1--3 everyday, bravely telling the truth about the corrupt government officials sent by the king to govern the colonies. Finally Zenger's long-awaited trial took place. The hostile judge dismissed Zenger's -5' local lawyers, making it necessary for his wife to seek out Andrew o Hamilton, a prominent Philadelphia lawyer. Persuaded by ; Hamilton, the jury bravely returned a not-guilty verdict, defying the judge's orders for a conviction. As a result of determination and bravery on the part of the colonists, a lasting victory for freedom of ' the press was gained by immigrant. 1.John Peter Zenger was a ________
- A. famous lawyer
- B. member of the Jury
- C. corrupt governor of New york
- D. Brave newspaper publisher

286 . No one knows when we started using colour, but we think that ancient cultures may have used colours to symbolize specific things. Research shows us that each culture had a different system for colour use. In other words, the people chose Nk hat the colours represented- blue in one culture could mean the opposite in another. Research suggests that over the years, we have learnt to recognize various colours as a warning. If a primitive man cut his hand and saw his blood, the red colour truly represented danger-it told him to do something about it or he could die. On the other hand, blue or green colour has a sort of healing. effect and helps people reduce their stresses. But the same person 7 would not eat meat if it was blue or green- something tells us that green or blue meat is bad. This is an experiment you can try for yourself with food colouring. Try serving a meal to your friends with the potatoes or rice coloured blue. You know that the food is harmless. but your guests will probably not eat it. And when they refuse the food, they are using a universal ability that humans have developed over thousands or years. 1.Which of the following summarizes the extract appropriately?
- A. Our colour prejudice
- B. Colour use in our culture
- C. Our fear for colours
- D. Colour and collar
