I'm taking a test and have to guess the right answer to the question after the article. Article: The rapid growth of cities worldwide over the next two decades will cause significant risks to people and the global environment, according to analysis. Researches from Yale and Stanford predict that by 2030 urban areas will expand by 590,000 square miles--nearly the size of Mongolia--to meet the needs of 1.47 billion more people living in urban areas. "It is likely that these cities are going to be developed in places that are the most biologically diverse," said Karen Seto, a famous scientist at Yale University. "They are going to be growing and expanding into forests, biological hotspots, savannas , coastlines--sensitive and _ places." Urban areas, they found, have been expanding more rapidly along coasts. "Of all the places for cities to grow, coasts are the most sensitive. People and buildings along the coast are at risk of flooding and other environmental disasters," said Seto. The study provides the first estimate of how fast urban areas globally are growing and how fast they may grow in the future. "We know a lot about global patterns of urban population growth, but we know significantly less about how urban areas are changing," she said. "Changes in land cover associated with urbanization lead to many environmental changes, from habitats loss and agricultural land conversion to changes in local and regional climate." The researchers examined studies that used satellite data to map urban growth and found that from 1970 to 2000 the world's urban footprint had grown by at least 22,400 square miles--half the size of Ohio. "This number is numerous, but, in actuality, urban land expansion has been far greater than what our analysis shows because we only looked at the published studies that used satellite data," said Seto. "We found that 48 of the most populated urban areas have been studied using satellite data, with findings in journals. This means that we're not tracking the physical expansion of more than half of the world's largest cities." Half of urban land expansion in China is driven by a rising...

I'm taking a test and have to guess the right answer to the question after the article. Article: As summer comes near, many children are really happy to forget about school for a few months. However, they might be taking that goal too seriously. Studies have found that children often forget between one and three months' worth of school learning during the summer months. Spelling and math abilities drop off the most, while reading is not really influenced by the time off. The main reason for this is because most children sometimes read outside of the classroom, whether newspapers, magazines, books, or video game guides. However, their math and spelling skills only get exercised in the school setting. The first purpose of summer holidays was to let farm children have time off to help work in the fields during the growing season, but this reason is no longer a good one since fewer kids actually work on farms today. Some cities in the United States, such as Los Angeles, have moved to a year-round school timetable, which may help reduce the loss of school skills that happens during the long summer holiday. To improve skills and to keep a good level of preparation, headmasters suggest trips to museums, summer camps, holidays with educational value, and visits to libraries to keep kids interested throughout the summer. There are other educational systems that provide holidays while still keeping students' skills up to date. For example, in Japan, students attend class for seven weeks in a row, followed by two weeks of holiday. This continues the whole year. In Italy, students attend class six days per week, but finish at 1: 30 pm each day, so that school does not run their life the way that it does in America, where students attend high school from 7: 45 am until 3: 00 pm each weekday. In areas where there are not enough classrooms--in Afghanistan or Somalia, for example--older students attend classes in the morning while the younger kids go to school in the afternoon. Headmasters fear that the three-month summer holiday stops the flow of learning. Just as students become used to new math problems or new ideas...

I'm taking a test and have to guess the right answer to the question after the article. Article: A light drizzle was falling as my sister Jill and I ran out of the Methodist Church, eager to get home and play with the presents that Santa had left for us and our baby sister, Sharon. Across the street from the church was a Pan American gas station where the Greyhound bus stopped.It was closed for Christmas, but I noticed a family standing outside the locked door, huddled under the narrow overhang in an attempt to keep dry. I wondered briefly why they were there but then forgot about them as I raced to keep up with Jill. Once we got home, there was barely time to enjoy our presents. We had to go off to our grandparents' house for our annual Christmas dinner. As we drove down the highway through town,I noticed that the family were still there, standing outside the closed gas station. My father was driving very slowly down the highway. The closer we got to the turnoff for my grandparents' house, the slower the car went. Suddenly, my father U-turned in the middle of the road and said, ''I can't stand it!" ''What?" asked my mother. ''They've got children. It's Christmas. I can't stand _ ." When my father pulled into the service station, I saw that there were five of them: the parents and three children--two girls and a small boy. My father rolled down his window. "Merry Christmas," he said. "Howdy ,''the man replied. ''You are waiting for the bus?'' my father asked. The man said that they were. They were going to Birmingham, where he had a brother and prospects of a job. "Well, that bus isn't going to come along for several hours, and you're getting wet standing here. Winborn is just a couple miles up the road. They've got a shed with a cover there and some benches". My father said. ''Why don't you all get in the car and I'll run you up there." The man thought about it for a moment, and then he beckoned to his family. They climbed into the car. They had no luggage, only the clothes they were wearing. Once they settled in, my father looked back over his shoulder and asked the children if... Question: Which of the follow words can best describe the father? Options: A: Kindhearted. B: Enthusiastic.
