But we do know that Harriet Tubman was one of the bravest women ever born in the United States. From a very early age,Harriet knew how slaves suffered. At six years old,she was sent to the fields. Working outside not only made her body strong but also made her learn about the Underground Railroad,on which she helped hundreds of people escape from slavery later. She also learned many things from the other slaves,which one day would help her lead her people to freedom. She became more of a rebel . In 1844,at about age 24,she married a free black man named John Tubman. By now,Harriet was sure she wanted to try to escape. Suddenly,the time came. Her owner died. Though opposed by her husband,she decided to escape. With the help of the Underground Railroad,and through a variety of suffering she finally crossed the border into Pennsylvania,where slavery was banned. Now that Harriet was free,she did not forget the hundreds of other slaves back in Maryland. Harriet traveled back and forth eighteen times,helping about 300 slaves escape into free territory. She became an expert at hiding from slave hunters. The people she helped called her Moses. At one time,anyone finding Harriet was promised $40,000 for catching her-dead or alive. During the Civil War,Harriet Tubman went into enemy territory to spy for the North. She also served as a nurse. After four years of bloody fighting,the North won the war. After the fighting ended,Harriet Tubman returned to Auburn,New York. She kept working. She traveled and gave speeches to raise money for better education for black children. She also worked for women's rights and housing. Harriet Tubman died in 1913.She was about 93 years old. By that time,she was recognized as an American hero. The United States government gave a funeral with military honors for the woman known as Moses. Question: Which of the following would be the best title for the text? Options: A: A History of American Black Slaves B: Cruel American Civil War C: Information on the Underground Railroad D: A Brief Introduction to Harriet Tubman

Read the article and select the best answer. Article: Research shows that humans switch from selfish to unselfish behavior when they are watched. Do you? A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box. Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched because they feel they will be rewarded for good behavior. Their report also referred to other research showing that this response of behaving well when watched is somehow _ into humans and people respond this way unconsciously, or without realizing it. It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning. The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption 'I Want You' It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese.

Ques: Read the article and select the best answer. Article: When you hear the word "farm", chances are you picture rolling hills in the country covered with cows and cornstalks. Some scientists, engineers and city planners say the farms of the future could rise straight into the air---in skyscrapers in the world's most populated cities. It might sound far--fetched, but in fact, some of the technology for growing crops indoors already exists. The scientists at the South Pole research station enjoy fresh salads every day from vegetables they grow in their own greenhouse. And NASA has been experimenting for years with methods for growing fresh fruits on the moon or even on Mars. As is known, traditional farming takes a plot of land as big as the entire state of Virginia just to grow enough food for 8 million people, says ecologist Dichson Despommer. Cities that can't grow their own food are often influenced by disasters such as hurricanes that can make it impossible for trucks to deliver fresh produce to grocery stores. In addition, fruit and vegetables grown outdoors face all kinds of dangers, from flooding to insect pests to weather instability, such as late or early frosts that can damage a crop. "You can control everything indoors. You can't control anything outdoors," Despommier says. To top it off, by the year 2050, the world population will grow by another 3 billion. "Where will we grow the food for all these people?" Vertical farming----growing crops in skyscrapers, tens of stories high----is the answer," says Despommier. Others say _ could provide new uses for hundreds of abandoned buildings in cities around the world. Crop waste, like leaves, would be composted , and the gases given off from composting would be used to heat the building. "I'd say it is going to be tough," says agriculturist Giacomelli. It can be tricky to regulate climate conditions indoors. Plus, plants differ in their weather and lighting requirements. Tomatoes like warm, sunny weather, while greens like lettuce prefer cooler temperatures. And nearly all crop plants require... Question: What attitude does Giacomelli have towards the vertical farming? Options: A: Positive B: Negative C: Uninterested. D: Uncertain
