Article: A study of older men in The Netherlands, known for its delicious chocolate, showed those who ate the same amount of one-third of a chocolate bar every day had lower blood pressure and a reduced risk of death. The researchers say, however, it's too early to conclude that it was the chocolate that led to better health. The men who ate more cocoa products could have eaten other food that made them healthier. Experts also point out that eating too much chocolate can make you fat -- a risk for both heart disease and high blood pressure. "It's why too early to make recommendations about whether people should eat more cocoa or chocolate," said Brian Buijsse, an expert for nutrition at prefix = st1 /WageningenUniversityin The Netherlands, who co-authored the study. Still, the Dutch Study, supported by grants from the Netherlands Prevention Foundation, appears to be the largest so far to document a health effect for cocoa beans. And it confirms findings of smaller, shorter-term studies that also linked chocolate with lower blood pressure. Researchers examined the eating habits of 470 healthy men who were not taking blood pressure medicine. The men who ate the most products made from cocoa beans -- including cocoa drinks, chocolate bars and chocolate pudding -- had lower blood pressure and a 50 percent lower risk of death. "This is a very important article providing epidemiological support for what many researchers have been observing is experimental models," said Cesar Fraga of the University of California Davis, who does similar research but was not involved in the new study. Could the study results apply to women? "Our study consisted of elderly inch," Buijsse said. "If you look at the other studies, you will see the same effects in men and women, younger people and older people. The findings may be _ to women, but you never know." Question: What is the main purpose of the text? - To encourage us to eat as much chocolate as possible. - To prove to us that eating chocolate can reduce blood pressure. - To inform us of a study about the health benefits of chocolate. - To warn us not to eat cocoa products because they can make you fat.
To inform us of a study about the health benefits of chocolate.

Read the following article and select the best answer. Article: On a cool summer night in Wyoming, Dean Biggins waits patiently in his truck. Suddenly, Biggins, a wildlife biologist, spots a pair of eyes in the distance. Baggins can't believe his luck: He's just caught sight of a black-footed ferret --one of the world's rarest animals. Just over a century ago, hundreds of thousands of black-footed ferrets lived on the grasslands in North America known as the prairie. But the animals died off as prairie dog disappeared. Black-footed ferret depend on prairie dogs for both food and shelter. After a ferret has eaten a prairie dog, it moves into the animal's burrow . When cattlemen started setting up ranches on the prairie in the early 1900s, they thought prairie dogs, which eat grass, might compete with their cattle and sheep for food. To make sure that didn't happen, they killed off billions of prairie dogs. As prairie dog populations dropped, black-footed ferrets disappeared. By 1979, researchers couldn't find any ferrets and declared the species extinct. Then, two years later, a small group was discovered. Although scientists were excited about the discovery, it soon became clear that the ferrets were in danger. A disease called sylvatic plague was killing the ferrets. Soon, just 18 ferrets remained. "To help the species survive, the researchers put all the ferrets in cages in 1986 and began raising them," says Randy Matchett, a wildlife biologist. To help the black-footed ferrets learn survival skills, wildlife biologists put them through a process called preconditioning. Researchers build a fence around old prairie dog burrows and put the ferrets in them when they are a couple of months old. While the animals get used to their new home, researchers feed them live prairie dogs so they can practice hunting. "Now about 1,000 black-footed ferrets are back in the wild. Despite their amazing comeback, black-footed ferrets aren't out of the woods yet," says Matchett. Sylvatic plague is still a threat, and ranchers still don't want too many prairie dogs on their land. "We... Question: How do scientists help the ferrets? - They take measures to stop the disease spreading. - They call on people to stop hunting the animals. - They set ferrets free when they are two months old. - They train the animals so they can survive in the wild.
