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.

          Mickey Mantle was one of the greatest baseball players of all time. He played for the New York Yankees in their years of glory. From the time Mantle began to play professionally in 1951 to his last year in 1968, baseball was the most popular game in the United States. For many people, Mantle symbolized the hope, prosperity, and confidence of America at that time.

          Mantle was a fast and powerful player, a “switch-hitter” who could bat both right-handed and left-handed. He won game after game, one World Series championship after another, for his team. He was a wonderful athlete, but this alone cannot explain America’s fascination with him.

          Perhaps it was because he was a handsome, red-haired country boy, the son of a poor miner from Oklahoma. His career, from the lead mines of the West to the heights of success and fame, was a fairy-tale version of the American dream. Or perhaps it was because America always loves a “natural”: a person who wins without seeming to try, whose talent appears to come from an inner grace. That was Mickey Mantle.

          But like many celebrities, Mickey Mantle had a private life that was full of problems. He played without complaint despite constant pain from injuries. He lived to fulfill his father’s dreams and drank to forget his father’s early death.

          It was a terrible addiction that finally destroyed his body. It gave him cirrhosis of the liver and accelerated the advance of liver cancer. Even when Mickey Mantle had turned away from his old life and warned young people not to follow his example, the destructive process could not be stopped. Despite a liver transplant operation that had all those who loved and admired him hoping for a recovery, Mickey Mantle died of cancer at the age of 63

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 43 to 50.

    Humans have struggled against weeds since the beginnings of agriculture. Marring our gardens is one of the milder effects of weeds - any plants that thrive where they are unwanted. They clog waterways, destroy wildlife habitats, and impede farming. Their spread eliminates grazing areas and accounts for one-third of all crop loss. They compete for sunlight, nutrients, and water with useful plants.

    The global need for weed control had been answered mainly by the chemical industry. Its herbicides are effective and sometimes necessary, but some pose serious problems, particularly if misused. Toxic compounds threaten animal and public health when they accumulate in food plants, groundwater, and drinking water. They also harm workers who apply them.

    In recent years, the chemical industry has introduced several herbicides that are more ecologically sound. Yet new chemicals alone cannot solve the world's weed problems. Hence, scientists are exploring the innate weed-killing powers of living organisms, primarily insects and microorganisms.

    The biological agents now in use are environmentally benign and are harmless to humans. They can be chosen for their ability to attack selected targets and leave crops and other plants untouched. In contrast, some of the most effective chemicals kill virtually all the plants they come in contact with, sparing only those that are naturally resistant or have been genetically modified for resistance. Furthermore, a number of biological agents can be administered only once, after which no added applications are needed. Chemicals typically must be used several times per growing season.

They compete for sunlight, nutrients, and water with useful plants.

    The global need for weed control had been answered mainly by the chemical industry. Its herbicides are effective and sometimes necessary, but some pose serious problems, particularly if misused. Toxic compounds threaten animal and public health when they accumulate in food plants, groundwater, and drinking water. They also harm workers who apply them.

    In recent years, the chemical industry has introduced several herbicides that are more ecologically sound. Yet new chemicals alone cannot solve the world's weed problems. Hence, scientists are exploring the innate weed-killing powers of living organisms, primarily insects and microorganisms.

    The biological agents now in use are environmentally benign and are harmless to humans. They can be chosen for their ability to attack selected targets and leave crops and other plants untouched. In contrast, some of the most effective chemicals kill virtually all the plants they come in contact with, sparing only those that are naturally resistant or have been genetically modified for resistance. Furthermore, a number of biological agents can be administered only once, after which no added applications are needed. Chemicals typically must be used several times per growing season.

The word "innate" in paragraph 3 is closest in meaning to________

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 43 to 50.

    Humans have struggled against weeds since the beginnings of agriculture. Marring our gardens is one of the milder effects of weeds - any plants that thrive where they are unwanted. They clog waterways, destroy wildlife habitats, and impede farming. Their spread eliminates grazing areas and accounts for one-third of all crop loss. They compete for sunlight, nutrients, and water with useful plants.
