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 9 to 13.

Scientists have experimented with a new procedure for alleviating the damage caused by strokes. Strokes are frequently caused by a blood clot lodging in the tree of arteries in the head, choking the flow of blood. Some brain cells die as a direct result of the stroke, but others also die over several hours because the proteins spilling out of the first cells that die trigger a chemical chain reaction that kills the neighboring cells.

The current method of reducing the amount of damage is to give a clot dissolver, known as TPA, as soon as possible. But generally TPA is not given to the patient until he or she reaches the hospital, and it still does not immediately stop the damage.

The new technology, still in the research stage, involves chilling the area or the entire patient. It is already known that when an organ is cooled, damage is slowed. This is why sometimes a person who has fallen into an icy pond is not significantly harmed after being warmed up again. The biggest issue is the method of cooling. It is not feasible to chill the head alone. Doctors have chilled the entire body by wrapping the patient in cold materials, but extreme shivering was a problem.

The new idea is to cool the patient from the inside out. Several companies are studying the use of cold-tipped catheters, inserted into the artery in the groin and threaded up to the inferior vena cava, which is a large vein that supplies blood to the abdomen. The catheter is expected to cool the blood that flows over it, thus allowing cooler blood to reach the area of the stroke damage.

It is not expected that the cooling will be substantial, but even a slight decrease in temperature is thought to be helpful. In effect, the patient is given a kind of forced hypothermia. And doctors believe it is important to keep the patient awake so that they can converse with the patient in order to ascertain mental condition.

Studies continue to determine the most effective and least damaging means of cooling the patient in order to reduce this damage.

The word “alleviating” in the first sentence is closest in meaning to _____.

A. causing

B. devastating

C. reducing

D. increasing

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   22  to  26

A.   Read the passage carefully, then choose the correct answer.

The ruined temples of Angkor are perhaps one of the mast impressive Seven Wonders of the World. Located in modern day Cambodia near Lake TonIe Sap, the largest freshwater lake in Asia, Angkor was the seat of power for the Khmer Empire from the ninth to the fifteenth century. The ruins of Angkor are documented as same .of the mast impressive ones in the world, rivaling the pyramids of Giza in Egypt. Why this mighty civilization died out is a question that archeologists are now only beginning to ponder. The answer, it turns out, may be linked with the availability of fresh water.

One possible explanation far the downfall of the Khmer Empire has to do with the inhabitants' irrigation system. The temple and palaces of Angkor were constructed around a series of artificial reservoirs and canals which were annually flooded to capacity by the Mekong River. Once filled, they were used to irrigate the surrounding rice patties and farmland during the course of the year. Farmers were completely dependent upon the water for their crucial rice crop. Without consistent irrigation, the farmers would have been unable to maintain functional crop production.

Scientists speculate that toward the end of the Khmer Empire the hydraulic systems of the reservoirs and canals broke down. The construction of hundreds of sandstone temples and palaces required an enormous amount of physical labor. In addition, as the capital of the Khmer Empire, Angkor contained upwards of one hundred thousand people who resided in and around Angkor. In order to feed so many people, the local farmers were driven to grow food quicker and more efficiently. After centuries of continual use, the irrigation system was pushed beyond its capacity. Soil erosion, nutrient depletion, and the loss of water led to decrease in the food supply. With less food available, the people of Angkor slowly began to migrate to other parts of Cambodia thus leaving the marvelous city of Angkor to be swallowed by the jungle. Therefore, it is speculated that the Khmer Empire may have fallen victim to its own decrepit infrastructure.

22. What is the passage mainly about?

A. Modern day agricultural procedures in Cambodia.

B. A possible explanation for the, decline of a civilization.

C. The essential role water plays in farming.

D. Religious temples of the ancient Khmer Empire.

23. The passage preceding the passage most likely discusses ______.

A. architecture of ancient Asian civilization

B. religious practices of the people of Angkor

C. the form of government practiced by the Khmer Empire

D. the other six wonders of the world

24. According to the passage, Lake Tonle Sap in Cambodia ______.

A. is an enormous fresh body of water in Asia

B. was unable to supply enough fish for the people of Angkor

C. became polluted due to a population explosion

D. is one of the Seven Wonders of the World

25. Why does the author mention the hydraulic systems of the reservoirs?

A. They supplied irrigation from the Indian Ocean.

B. They became non-functional due to overuse.

C. They were destroyed by nearby warrior tribes.

D. They helped transport the sandstones for constructing temples.

26. It can be inferred from the passage that the inhabitants of the Khmer Empire ______.

A. were intentionally starved by the farmers

B. lost their food source due to excess rainfall

C. supplemented their diets with 'meat hunted in the nearby jungles

D. depended upon rice as their main source of food

27. All the following are mentioned as events that can affect food supply EXCEPT.

A. erosion of soil                                       B. contamination of soil

C. reduction of nutrients                            D. loss of water supply

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. 

Smog is a combination of smoke and fog It occurs when gases from burnt fuel mix with fog on the ground. When heat and sunlight get together with these gases, they form fine, dangerous particles in the air.

Smog occurs in big cities with a lot of traffic. Particularly, in the summertime, when it is very hot, smog stays near the ground. It is dangerous to our breathing, and in smoggy areas, we cannot see very well.

Smog was first discovered in Great Britain in the 19th century, during the beginning of the Industrial Revolution. At that time, people used coal for heating and cooking. Factories also used coal to produce iron and steel. Smoke mixed with wet, foggy air and turned yellow. The smog often hung over cities for many days. It caused lung diseases and breathing problem. Thousands of people died in London every year.

Today, cities that have a large population and are located in hot, subtropical areas have the biggest smog problems - for example, Los Angeles, Mexico City and Cairo.

Question 28. Where can smog possibly be found?

A. At a place where it is rainy

B. At a place where the traffic is heavy and the weather is foggy

C. In a city where many people smoke

D. Underground

Question 29. In the first paragraph, the word fine is closest in meaning to

A. tiny B. good C. harmful D. shiny

Question 30. What will happen if smog stays close to the ground?

A. It will disappear in a short time B. It will make the sky cleaner.

C. It will harm our health and block our sight. D. It will cause many storms.

Question 31. What probably caused the smog in Britain at the beginning of the Industrial Revolution?

A. There were too many cars in the country.

B. The weather there was too foggy.

C. People smoke a lot at that time.

D. Factories and people used coal as energy.
