Article: Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin . Although known as the love hormone, it affects the sexes differently. "Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status," said Professor Ryan. Generally, people believe that the hormone exytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interaction such as falling in love or giving birth. But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy. Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship. Professor Ryan's recent experiment used 62 men and women aged 20 to 37. Half of the participants received oxytocin. The other half received placebo . [( )] [( :Love my Dog.)] After a week, the two groups switched with participants. They went through the same procedure with the other material. Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions. The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better. Professor Ryan thus concluded: "Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factor that are mainly hormonal."

Article: The idea of sailing west to reach the riches of the East Indies and the Asian mainland was much in fashion with cultured Europeans during the late fifteenth century. Learned people agreed that the earth was round: their only questions were how long and how dangerous would be a trip to reach the Orient. Christopher Columbus, the son of an unknown weaver, and himself a weaver of ambitious dreams, made his historic voyage to the New World in 1492. He didn't go to school very much, but be learned to read and write Spanish during his travels. He also taught himself Latin because all the geography books were written in Latin. Sailing with a tiny fleet of three ships, the Santa Maria and two smaller ships, the Pinta and the Nina and a crew of ninety sailors, be found the thirty-three-day crossing easier than his nearly-decade-long effort to find royal sponsors willing to support it. The trip drew not only on his own skills as an expert ship's captain, but also on his ability to plan such an expedition, obtain governmental approval and financing, and finally, demonstrate its success so that such explorations could continue. He tried for years to get King Ferdinand and Queen Isabella to supply him with ships and money. Finally they agreed, but he made more demands. He wanted to be made a knight, admiral of the Ocean Sea. He wanted to be the viceroy and governor general of all lands he would discover. Also he wanted one-tenth of everything he found of value in the new lands. The explorations that followed Columbus-those of Cabot, Verrazano, Cartier, and many others-benefited from a new maritime technology borrowed from Arab sailors and from a variety of new vessels (,) such as the light-weight caravels employed by Columbus. Sailors also perfected sails and various types of riggings that gave ships added stability and greater maneuverability on the open seas. And when leaving sight of the coast, new navigational aids-charts, compasses, and astrolabes-permitted them to determine their position with some, though not perfect, accuracy. Columbus himself made a total of four voyages to the New World but he did not become rich as he had hoped. At the end of his life he only had a pension the king and queen had given him because he was the first to reach the New World. He spent the last few months of his life in bed because of the pain of arthritis . Columbus not only discovered a New World, but led the way for other explorers.
Answer: The oriental countries.
