In repeated tests, rats freed another trapped rat in their cage, even when yummy chocolate served as an attraction.24 of the 30 rats opened the trap by pushing in a door.The rats could have eaten the chocolate before freeing their partners, but often didn't, choosing to help and share the goodies. "Basically they told us freeing another rat is as important as eating chocolate," said study author Peggy Mason of the University of Chicago."That's a very striking thing." In some cases, the rats first took the chocolate chips out of a container, but didn't eat them, then freed the other rat and shared "almost as if they were serving them chocolate," Mason said.The research is reported in Thursday's journal Science. Also, females showed more consistent care and help than males, Mason said.All six females freed their trapped partner while three quarters of the 24 males did so.This confirms other studies that show females showing more pro-social behavior than males.There were time when the male rats took the day off from helping their trapped partner, but the females never did, she said. Jeff Mogil at McGill University in Canada, who wasn't part of the study, said it was a little surprising but even more convincing. Both scientists said social understanding is probably a characteristic that is important in the evolution of animals. Mason joked that if rats can be so caring and helpful, "there's a sense of optimism.It's something we could be."

input: Please answer the following: Write a multi-choice question for the following article: Article: Elderly adults who regularly drink green tea may stay more agile and independent than their peers over time, according to a Japanese study that covered thousands of people. Green tea contains antioxidant chemicals that may help stop the cell damage that can lead to disease. Researchers have been studying green tea's effect on everything from cholesterol to the risk of certain cancers, with mixed results so far. They found those who drank the most green tea were the least likely to develop "functional disability", or problems with daily activities or basic needs, such as dressing or bathing. Specifically, almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled, compared with just over 7 percent of people who drank at least five cups a day. The study did not prove that green tea alone kept people agile as they grew older. Green-tea lovers generally had healthier diets, including more fish, vegetables and fruit, as well as more education, lower smoking rates, fewer heart attacks and strokes, and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. But even with those factors accounted for, green tea itself was tied to a lower disability risk, the researchers said. People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk. Although it's not clear how green tea might offer a buffer against disability, Tomata's team did note that one recent study found green tea extracts seem to increase leg muscle strength in older women. While green tea and its extracts are considered safe in small amounts, they do contain caffeine and small amounts of vitamin K, which means it could affect drugs that prevent blood clotting .

input: Please answer the following: Write a multi-choice question for the following article: Article: Volleyball has become a worldwide sport that is popular with all age groups, but when did this fun sport start? The history of volleyball dates back to 1895 when William G.Morgan met a Canadian James Naismith, inventor of basketball and was influenced by him and basketball.Then he wanted to invent a new game that was fit for middle-aged men. Morgan enjoyed the game of basketball, but soon he realized that it was too fast paced for some of the older men.So, he decided to invent a game that was still played on a court , but the players were not required to run up and down--he created the game of "mintonette." Volleyball history shows that the original game of mintonette was played on a full court with a net in the middle.Two teams tossed the ball back and forth over the net, similar to the game of badminton.In order to cut down the equipment costs, the players played the ball with their hands. The game quickly became popular, and everyone wanted to learn how to play volleyball.It quickly spread to other areas, across the United States, and even to other countries.Several changes were made to the game. Then specific volleyball rules were set into place.Some of the rules of volleyball included the court size, number of players, and number of hits per team.The rules also stated that players must rotate around the court so that everyone had a turn to serve the ball.Also, a standard volleyball size and shape were decided within a few years.The rules continued to change and adjust throughout the history of volleyball, until the game became what we have today. Even though volleyball history says that the game was originally created for middle-aged men, the game has become so popular among all kinds of people.Today there are many different kinds of competitive volleyball teams: high school volleyball, college volleyball, women volleyball, men, children, mixed teams, etc.There is an endless amount of possibilities with this game because it is easy to learn, many people can play together, and it can by played indoors or outside.
