Read the article and select the best answer. Article: Protagoras was among the great teachers of ancient Athens. He taught many subjects, including the laws of argument and the right use of language. It is said that he was the first teacher to accept money for his services. A student, Evalthus, heard of this famous teacher and asked him to give him lessons. However, Evalthus didn't want to pay for his lessons at once, and after some discussion it was finally agreed between them that Evalthus should pay only if he won his first case in the court. For if he won, it would prove that he had been taught well. The lessons began and Evalthus proved himself to be a good student. But he refused to pay Protagoras anything at the end of his studies. Protagoras therefore took Evalthus to the court and told the judges that he wanted his money. He explained that he must be paid whether he won or lost the case. "Whatever you decide," he declared to the judges, " I must be paid. For if you decide in my fovor , then I win the case, and so I must be paid . But If you decide against me, then Evalthus has won his first case in the court; according to our agreement, he must pay his lessons. Therefore I shall get my money whatever happens." The Athenian judges found no fault in it, so they asked Evalthus to reply. "No, it's quite clear," said Evalthus, " that I need not pay. If the judged decide in my favor, then I have won the case, and I need not to pay. But if Protagoras wins, then I have lost my first case. Therefore, according to our agreement, I do not have to pay. So I need not pay in any event." As both arguments appeared to be faultless, the judges were unable to come to a decision. They therefore ordered the two men to appear before them again one hundred years later. Question: What is probably the best title for the text? Options: A: A Smart Student---- Evalthus B: A Great Teacher---Protagoras C: Come Here One Hundred Years Later D: A Fight Between Teacher and Student

Read the article and select the best answer. Article: Scientists have devised a way to determine roughly where a person has lived using a strand of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims. The method relies on measuring how chemical variations in drinking water show up in people's hair. "You're what you eat and drink, and that's recorded in your hair," said Thure Cerling, a geologist at the University of Utah. While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move. Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes . The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months. Cerling's team collected tap water samples from 600 cities and constructed a map of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of rain systems. "It's not good for pinpointing ," Cerling said. "It's good for eliminating many possibilities." Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake. The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair. When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before her death, she moved about every two months. She stayed in the Northwest, although the test could not be more specific than somewhere between eastern... Question: What did Cerling's team produce in their research? Options: A: A map showing the regional differences of tap water. B: A collection of hair samples from various barber shops. C: A method to measure the amount of water in human hair. D: A chart illustrating the movement of the rain system.

Read the article and select the best answer. Article: Green living has become more important than ever and as time goes by, it will only become a more important issue. While it used to be a matter of making an extra effort to save energy and reduce waste in our homes, this has extended to the professional side of things since. Public buildings, such as schools, hospitals and offices, are under an increasing amount of pressure to make the change and go green, even if it's just a step-by-step process that takes a few years to implement completely. There are plenty of reasons for offices to go green and these reasons go beyond the concept that it should be done just for the sake of the environment. While the environment is incredibly important and vital to our survival and quality of life, sustainable office design can also have positive impacts upon employees and people using the building. For example, a report carried out last September revealed that the way an office is designed can significantly impact on the health of the staff there. It was also found to have an effect on productivity and could be a contributory factor to the amount of sick leave and staff turnaround within the business. It's fascinating to think that people can be so sensitive to their environments but it also makes a lot of sense. Even the choice of colour in your office can negatively or positively affect the people working there. Based on this study, it is clear that companies should be making more efforts to improve on the office design while making sure the environment is sustainable and green. There are various little changes that can be made to lead to something bigger, from making sure the lights are turned off at night to recycling the paper your company gets through on a weekly basis. Once these changes are in place, you can start looking at the bigger picture and begin implementing changes to design and construction, like having wood fibre insulation fitted. Along with other sustainable features, insulation can be beneficial in various ways. Not only will an insulated office... Question: What is the author's argument in the passage? Options: A: Green living can help to save energy. B: Public buildings should go green. C: Green living still has a long way to go. D: It is important to lead a green life.
