Example Input: Article: One day a student was taking a walk with his teacher. As they went along, they saw a pair of old shoes lying in the path. They were a poor farmer's, who was working in the nearby field. The student turned to the teacher, saying: "we will hide his shoes, and hide ourselves behind those trees, and wait to see what he will do." "My young friend," answered the teacher, "we should never make fun of the poor. Why not put a coin in each shoe, and then we will hide ourselves and watch?" The student did so and they both hid themselves behind the trees. The poor man soon finished his work, and came across the field to the path where he had left his coat and shoes. After putting on his coat, he put his foot into one of his shoes, and felt something hard. Then he bent down to feel what it was, and found the coin. Surprised, he looked at the coin, turned it around and looked at it again. He then looked around, but no person was seen. He put the money into his pocket, and continued to put on the other shoe. His surprise was doubled on finding the other coin. He couldn't control his feelings and fell to his knees, looked up to the sky and expressed his thanks. Then he spoke of his wife, sick and helpless, and his children without bread. He said the help would save them from dying. The student stood there deeply moved, and his eyes filled with tears. "Now," said the teacher, "are you not much happier than if you had hidden the shoes?"

Example Input: Article: To the untrained eye it might seem like just a bit of a monkey trick. But when Milly the mandrill (, ) covers her face with her hand she is actually sending a serious message to her fellows: "Leave me alone!" Experts believe the 15-year-old mandrill invented the gesture to warn other monkeys at Colchester Zoo to give her some space. And, surprisingly, the signal has been picked by other members of the group, who use it when they too require _ . Biologist Mark Laidre believes the behavior is evidence of social culture among the mandrills. Importantly, the sign language is unlikely to have been influenced by human activities because mandrills do not copy humans. Mr. Laidre expects further research will uncover other monkeys using cultural gestures -- the ability to communicate with the hands in a meaningful way. "By covering their eyes with their hands, possibly conveyed to others that they wanted to be left alone and this message may have been respected as a 'do not disturb' sign," said Mr. Laidre. While the hand is in place, other monkeys are not likely to approach or touch the monkey. Those who rank lower in the social order also use the technique to avoid attacks from more powerful group members. As the discovery appears to be unique to Colchester Zoo, it suggests it is a local phenomenon that arose naturally in the community of 25 mandrills. Curator Sarah Forsyth said: "We believe Milly made up the signal and over the past five years some of the younger mandrills have picked it up. We're not sure why she started doing it but it could be as simple as 'I can't see them, so they can't see me'. It really does show you how intelligent mandrills are."

Example Input: Article: Teamwork is all about working together to achieve a common goal or purpose.Is teamwork out of date?Why it is so hard to effectively conduct teamwork in those things? One way we employ teamwork in everyday lives is by becoming a parent.It is a parent's job to teach their children the fundamental skills and give them the knowledge they need to be successful in life.So why is teamwork disappearing in this aspect of our lives?Well in today's society,we find that more and more parents are experiencing that the teamwork is one-sided thing.According to a 2009report from the US,there are 13.7million single parents raising their children in the US and this amount could be due to the fact that parents are not stepping up and taking responsibility for their children or they don't have the means to,so they leave one parent to do it by themselves.This is a saddening fact,but it reflects that effective teamwork is losing ground in the parenting aspect of our everyday lives. Another place where teamwork affects us greatly is in our jobs.It doesn't matter if you are a small or large company; if you have at least one employee and yourself,then teamwork will be present.I have noticed that with the current economic recession ,people are racing to grab jobs but the quality of people work has gone down greatly.It just appears to me that people do not take part in their work anymore.They want to get to work and work as fast as they can,just to receive the paycheck,but their quality standards flew right out the window.This type of behavior is where I think teamwork is losing its ground in the workforce.There are too many people who want to work independently and forget they are a part of a team. As you can see,we run into the aspects of teamwork in just about everything we do.Do you believe teamwork is really losing ground in today's society?I think it is.What's your opinion?

Asnwer: A
