Question: Read the following article and select the best answer. Article: A mouse looked through a crack in the wall to see the farmer and his wife opening a package; what food might it contain? He was astonished to discover that it was a mouse trap! Running to the farmyard, the mouse shouted, warning everyone, "There is a mouse trap in the house, there is a mouse trap in the house." The chicken, with her head high, glared at the mouse and said, "Shut up. Little Ugly. This is a great concern to you, but it has nothing to do with me; I can't be troubled by it. The mouse turned to the pig and told him, "There is a mouse trap in the house." "I am so sorry, Mr. Mouse," said the pig sympathetically, "but there is nothing I can do about it but pray; you are always in my prayers." The mouse turned to the cow, who relied, " A mouse trap, am I in great danger, huh?" Now the mouse had to face the farmer's mouse trap alone. The very night a sound was heard through the house, like that of a mouse trap catching its . The farmer's wife rushed to see what was caught. In the darkness, she did not see it was a big poisonous snake whose tail the trap had caught. The snake bit the farmer's wife. The farmer rushed her to the hospital. She returned home with a fever. It is said that drinking fresh chicken soup will help treat fever, so the farmer took his sharp knife to the farmyard for the soup's main ingredient. His wife's sickness continued, so friends and neighbors came to sit with her around the clock. To feed them, the farmer killed the pig. The farmer's wife did not get well, in fact, she died, and so many people came for her funeral. The farmer had the cow killed to provide for all of them to eat.

Volunteering in Nursing Homes According to the National Center for Health Statistics,"Over 50% of those living in nursing homes do not have close relatives and 46% have no living children." Life in a nursing home is lonely,confusing,and frightening for many residents.

Question: Read the following article and select the best answer. Article: Can you imagine traveling to work in a one-man submarine? Scientists believe that someday one-man submarines will be as numerous as automobiles today. One says," One day soon, men will walk on the ocean floor as they do on the street. " Perhaps during your life time, people will travel, work and live under the sea. Ships carrying oil and articles of trade will move beneath the ocean. Passenger ships will be built to travel underwater, where storms cannot delay them or make people seasick. Special underwater ships will be designed for mining, fishing, and exploring unknown areas. For military use, there may be submarines that can fly and then dive underwater to approach the battle area without being seen. First, however, the human problems associated with living in the ocean will need to be studied in detail. Many of these problems are the same as the problems of living in outer space: pressure, lack of oxygen, and weightlessness. Already scientists have begun to study these problems. In 1963 and 1964 scientists and Navy divers lived and worked underwater for several days in two projects which were called Sealab I and Sealab II. The Sealab II experiment kept the scientists and divers 215 feet below the surface for thirty days, studying marine biology, temperature, pressure, currents, and ocean bottom geology. Many puzzling questions remain unanswered, however. Man's warm blood makes it difficult for him to live long in the sea without some kind of warmth. Can our blood be changed to fit new water surroundings? What will happen to our muscles if we live in the water very long? Will they become soft away from our usual land existence? Will bones become weak and our blood pressure change? Scientists are searching for answers. By studying plants and animals deep in the ocean, scientists may find a cure for some of our most serious human diseases. We may learn to use plants to increase our world food supply. Engineers may learn to use the power of the sea by building huge walls to catch the force of... Question: To become used to living in the sea, we should try to _ - increase the amount of our blood - keep our blood warm - soften our muscles - warm our bones
Answer:
keep our blood warm
