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? Options: A: She has done the research by herself. B: Her research was based on two studies. C: Her research lasted about three years. D: People should eat all kinds of nuts every day.

Read the article and select the best answer. Article: A small dog should be _ after eating a handful M&M's, at least according to conventional wisdom. But watching "Moose", a friend's five-pound Chihuahua, race around a living room after his sweet snack makes one wonder: Is chocolate truly poisonous to dogs? Dogs and humans have similar tastes. But unlike humans, our companions experience dangerous effects from eating chocolate --it can poison them and in some cases is fatal. Chocolate's danger to dogs depends on its quality. Chocolate is processed from the bitter seeds of the cocoa tree, which contain a family of compounds known as methylxanthines . This class of substances includes caffeine and the related chemical theobromine . Chocolate contains a significant amount of theobromine and smaller amounts of caffeine. These chemicals can cause a dog's heart to race up to twice its normal rate, and some dogs may run around as if "they drank a gallon of espresso ," according to Hackett. Dogs are capable of handling some chocolate, but it depends on the animal's weight and the type of chocolate it eats. Unsweetened baking chocolate contains more than six times as much theobromine as milk chocolate, although amounts vary between cocoa beans as well as different brands of chocolate. Less than four ounces of milk chocolate is potentially fatal for Moose and other small dogs. Around every confection-centered holiday -- Valentine's Day, Easter and Christmas -- at least three or four dogs are hospitalized overnight in the animal medical center at Colorado State. But in 16 years, Hackett has seen just one dog die from chocolate poisoning, and he suspects it may have had an underlying disease that made it more exposed to chocolate's heart -racing effect. Question: What can we learn about Hackett? Options: A: He is a vet. B: He is a pet shop owner. C: He is the owner of Moose D: He is a doctor in a small hospital.
