Read the following article and select the best answer. Article: A new American report says water-related problems will likely increase tensions around the world in the next ten years. These problems include water shortages, poor water quality and floods. The problems will increase the risk of failure of governments. However, countries are unlikely to go to war over water. But the real question is that some governments may use water as a weapon to pressure others ten years later. The report looks at possible effects of water problems on the United States national security interests over the next thirty years. It says the areas that will be most affected by water problems are North Africa, the Middle East and South Asia. The United States Secretary of State Hillary Clinton says, "Reliable water resources are essential for feeding the hungry, running industries and creating energy. Certainly they are central when we think about how climate changes will affect future generations." The report also predicts an increased demand for American assistance and expert help to solve those problems. That demand for help could create opportunities for leadership and influence. Water shortages, poor water quality, and floods are unlikely to result in state failure. But these could combine with poverty, social tensions, environmental problems, poor leadership and weak governments to produce social disorder. And that combination could cause state failure. The report predicts that from now through 2040 water shortages and pollution probably will harm the economic performance of important trading partners. During the next ten years the loss of groundwater supplies in some agricultural areas will create a risk to national and global food markets. These shortages will be a result of poor management. Agriculture uses about seventy percent of the world's freshwater. The report says technology that reduces the amount of water needed to grow crops will offer the best way to fight against water shortages. Question: What can be inferred from this passage? - Water pollution does more harm to the economic performance. - The loss of groundwater supplies has threatened global food markets. - Technology that reduces water use in agriculture should be developed. - Developing technology that produces freshwater is the best way of fighting water shortages.
Technology that reduces water use in agriculture should be developed.

Ques: Read the following article and select the best answer. Article: A couple of years ago on a hot summer day in south Florida, a little boy decided to go for a swim in the old swimming hole behind his house. In a hurry to dive into the cool water, he ran out of the back door, leaving behind shoes, socks, and shirt as he went. He flew into the water, not realizing that as he swam toward the middle of the lake, an alligator was swimming toward the shoe. His mother in the house was looking out of the window and saw the two as they got closer and closer together. In great fear, she ran toward the water, shouting to her son as loudly as she could. Hearing her voice, the little boy became worried and made a return to swim to his mother. It was too late. Just as he reached her, the alligator reached him. From the bank. the mother caught her little boy by the arms just as the alligator _ his legs. That began a tug-of-war between the two.

A farmer happened to drive by, heard her screams, raced from his truck, took aim and shot the alligator. After weeks and weeks in hospital, the little boy survived. His legs were extremely scarred by the attack of the animal and on his arms were deep scratches where his mother's fingernails dug into his flesh in her effort to hang on to the son she loved. The newspaper reporter, who interviewed the boy after the injury, asked if he would show him his scars. The boy lifted his pants legs. And then, with obvious pride, he said to the reporter. "But look at my arms. I have great scars on my arms, too. I have them because my mom wouldn't let go. Question: What did the boy think of the scars on his arms? - fearful. - Shy. - worried. - Proud.

Ques:Read the following article and select the best answer. Article: Many American youngsters earn their own allowance by doing temporary jobs for their neighbors. Babysitting is one of the common of these jobs. Most couples do not have maids or relatives living with them, and they need to have someone watch the children if they want to go out. Another way is by mowing lawn in summer and clearing snow from sidewalks and driveways in winter. Many people mow their own lawns,but often people prefer to give the job to a neighbor's child. In winter, snow clearing from streets and highways is the government's responsibility. Homeowners or tenants, however, must clear sidewalks and driveways. Since clearing snow is very tiring, many people prefer to hire teenagers for this job rather than do it themselves. Besides, many American teenagers usually work two to three hours after school and all day on Saturday or Sunday at the local supermarket. They work as cashiers or stockroom clerks. Or they help customers carry things to their cars. Other favorite jobs are waiting on tables in restaurants or working part-time at stores or gas stations.
