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.
Her research was based on two studies.

Q: Read the following article and select the best answer. Article: The American tradition of Thanksgiving dates back to colonial times, to the Pilgrims of Plymouth rock Colony. To escape religious persecution in England, the Pilgrims journeyed to the New World on their ship, the Mayflower. After a long journey, they finally arrived at Plymouth Rock in autumn of 1620. They could not finish building the settlement before winter, so many froze to death. They ate most of their food on the journey over, so many also starved. However, the Pilgrims met a Native American named Tisquantum, or Squanto as he was better known, who taught them how to plant corn and catch eel . By the same time next year, the Pilgrims had built a steady settlement, and had a bountiful harvest. To thank the Native Americans for their help and to celebrate the harvest, the Pilgrims held a grand banquet . Together, they feasted on corn, yams, fish, and most importantly: roast turkey, which became the highlight of the modern Thanksgiving feast. Schools always make a big deal about Thanksgiving, because they feel that it teaches children how to be thankful and to treat others with kindness. I spent the many years of elementary school making paper turkeys, fake cornucopias(a shell filled with food, a symbol of the holiday), and writing lists of what I'm thankful for. When I grew older, I watched movies and read books about the First Thanksgiving, and completed crossword puzzles and word searches filled with holiday themed words. While the idea for Thanksgiving is great, and it is a wonderful opportunity to instill certain values in children, I don't think we should name a special holiday for being thankful. We should be thankful for what we have every day, not just Thanksgiving. Question: What's the main reason for the English Pilgrims to leave their home country? - Political ideas. - Religious beliefs. - Hard life. - Hopes for fortune.
A: Religious beliefs.

Q: Read the following article and select the best answer. Article: Americans often plan social gatherings on short notice, so don't be surprised if you get invited to someone's home or to see a movie or baseball game without much warning. If the time is convenient for you, surely accept their invitation. But if you're busy, don't be afraid to _ the invitation, perhaps suggesting a time that would be better. Your host won't be shamed. Invitations are usually sent in person or over the telephone. The main exception is for some formal occasions, in which case a written invitation will be mailed. You would normally receive a written invitation to a wedding . For a casual dinner invitation, don't arrive more than 5 minutes early, because your host may still be preparing for your visit. Arriving more than 10 minutes late is considered rude if very few people were invited. If many people were invited, it's OK to arrive a little late, even as much as half an hour late. For example, it's OK to arrive late for a party, for a potluck dinner or for a social gathering inviting a large group of people. If you're invited for dinner, it's proper to bring the host a bottle of wine, a gift basket of fruit, a box of candy , or a bouquet of flowers. Don't bring roses, as men often give roses to women on a date . If you wish to thank the host for his or her hospitality , it's right to call or send a brief written thank-you note the next day. Question: The passage is to tell us _ . - how to accept Americans' invitations. - something about American social visits. - something about American business visits. - how to make a living in America.
A: something about American social visits.
