Example input: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Q: Article: In the last years of the Warring States period, the State of Qin attacked the State of Wei on a large scale repeatedly and occupied large areas of land, for the State of Wei was too weak to defend itself. In 273 B.C., the Qin army launched a more serious attack upon the State of Wei than ever. The king of the State of Wei gathered his officials, and asked with a worried look if anyone could propose a way to defeat the Qin army. After years of chaos caused by the wars, the officials trembled when fighting was mentioned, and no one dared to speak of resistance. At the critical moment when a large enemy force was bearing down upon the border, most of the officials persuaded the king to peace, at the cost of giving away to the State of Qin the large area of land north of the Huanghe River and south of the Taihang Mountain. However Su Dai, a counselor, did not agree. He hurried up to the king and said, "Your Majesty, they don't think about the interests of the country at all. It is just because they are afraid of death that they ask you to sue for peace by betraying the country. Of course you can temporarily satisfy the ambition of Qin, but it will never stop attacking us until our land is totally given away." He added,"Once there was a man whose house was on fire. People told him to put out the fire with water, but he would not listen. Instead, he carried a faggot to put out the fire, only to make the fire fiercer. Isn't it similar to carrying faggots to put out a fire if you agree to sue for peace at the cost of the land of the State of Wei?" Though Su Dai's argument was very convincing, the king accepted the suggestion of those officials and gave away to the State of Qin a large area of the land of the State of Wei. As might be expected, the Qin army attacked the State of Wei in 225 B.C. again, surrounding the capital city Daliang and flooding it by digging open the dykes of the Huanghe River. The State of Wei was finally destroyed.
