Read the following article and select the best answer. Article: The cold wind cut through my enthusiasm as a tourist in Washington D.C., so I entered the nearest restaurant for warmth. I ordered a hot cup of coffee, and began observing people. Some people were having dinner in the great hall, which made me consider an early dinner. At that time, I observed a man seated nearby and, from his eager eyes, I realized that he noticed the delicious food. His tired body and worn clothes shouted, "Homeless, homeless!" I wondered how long it had been since he had eaten. I expected him to approach me for a handout . He never did. A silent war broke out in my head --one side was telling me to mind my own business, and the other was urging me to offer him the food. While my inner debate moved on, a well-dressed young couple walked up to him. "Excuse me, sir," the husband began. "We just finished eating, and our appetites weren't as big as we thought. We hate to waste good food. Can you help us out and put this to use?" He gave the man some food. "Thank you. Merry Christmas!" the man replied. The man carefully watched his new food, and was about to drink the soup and eat the food seriously. Something that happened next shocked me. An old man, with pants, an old jacket and open shoes, entered the hall and walked to our direction. The man who was just offered the food saw the situation. Setting aside his meal, he stood up and guided the old man to the table. Then he put his worn jacket over the old man's shoulders. "Hi, my name's Jack," he said, "and one kind person brought me this meal. I just finished eating and hate to waste good food. Can you help me out?" The old man answered gratefully, "Sure, but only if you go halfway with me on that sandwich." I left the restaurant that day feeling warmer than I had ever thought possible. Question: What can we learn about the old man according to the text? - He accepted the food given by the kind couple. - He was shameful of his own appearance. - He expressed thanks to Jack after being helped by him. - He had known Jack before he entered the restaurant.
He expressed thanks to Jack after being helped by him.

Fifi was outside, and they were frightened. By the time Fifi had left, 8,000 people were dead, Fifi wasn't a pet dog as the name suggests. It was a hurricane, one of the most destructive natural phenomena in the world. Why do we give human names to storms and hurricanes? We didn't always. Two hundred years ago, many hurricanes in the Caribbean were named after the saint's day on which the storm occurred. Later, storms were known by the name of the city where they came ashore. Meteorologists then tried naming storms after the latitude and longitude where they occurred. Finally, in 1953, hurricanes started getting people's names --specifically, female names. Male names were added in 1979. There are six sets of names for what the experts call "Atlantic tropical cyclones"( ). Each list is used every six years and consists of 21 names, starting with every letter but Q, U, X, Y ,Z. the names alternate between male and female. A storm won't get a name until its winds reach 39 mph or about 62.4 kph, at which point it becomes a tropical storm. At 74 mph or 118.4 kph it's declared a hurricane. The 126 names on the list are used only for storms that form off the Atlantic coast of the US. There are separate lists for the Pacific. So what happens if a hurricane should cross from the Atlantic to the Pacific? It's happened before. The storm just gets a new name and sometimes a new sex. Max Mayfield is the director of the National Hurricane Centre, headquartered in Miami, Florida. He is in charge of picking new names for storms off the Atlantic coast. He doesn't do it alone, though. His _ in two dozen other countries in the Caribbean, Central America and North America vote on what names will replace retired names. Question: Which of the following is true according to the passage? - There were no hurricanes two centuries ago. - The Caribbean is a state of the United States. - The Caribbean is a place where hurricanes occur often. - Fifi was formed off the Pacific.
The Caribbean is a place where hurricanes occur often.

Read the following article and select the best answer. Article: Eat nuts, live longer. Researchers have found that those who eat a handful of peanuts every day significantly decrease their risk of dying from all causes compared to those who do not eat nuts. A new study concludes that all types of nuts seem to be protective. Researcher Ying Bao is with the Department of Medicine at Brigham and Women's Hospital and Harvard University Medical School in Boston, Massachusetts. She and her colleagues looked at the impact of nut consumption by analyzing two huge studies that began in 1980 - the Nurses' Health Study, which tracks the of more than 76,000 women, and 42,000 men enrolled in the Health Professionals Follow-up Study. Among the questions asked at the beginning of the studies was, 'how frequently do you eat nuts?' The information was updated every two to four years. Bao says the participants were followed for three decades. "What we observed is that people who eat more nuts are less likely to die over the next 30 years," said Bao. "So, for example, if a person eat(s) nuts once per day, that person has a 20 percent lower risk of dying." Bao says eating a handful of nuts five or more times per week was associated with a 29 percent reduced risk of dying from heart disease and an 11 percent lower risk of cancer death. A serving size is 28 grams. Nuts contain nutrients, including high quality proteins, vitamins and minerals, all of which have anti-cancer effects and may help protect the heart. Bao says researchers are planning studies to find out how nuts are beneficial to human health. The study on the health benefits of nuts was funded by the International Tree Nut Council Research and Education Foundation. Question: About Bao's research, which statement is true? - She has done the research by herself. - Her research was based on two studies. - Her research lasted about three years. - People should eat all kinds of nuts every day.
**Answer**
Her research was based on two studies.
