Read the following article and select the best answer. Article: What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science? We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work. What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves. He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum . He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively. Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation. Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place. These seem to be some of the ways in which a successful... Question: Which of the following statements about a curious scientist is TRUE? - He doesn't find confidence and pleasure in work. - He is interested in problems that are explained. - He makes efforts to investigate potential connections. - He looks for new ways of acting.
He makes efforts to investigate potential connections.

Read the following article and select the best answer. Article: Telephone, television, radio, telegraph and the Internet all help people communicate with each other. As a result, ideas and news of events spread quickly all over the world. For example, within seconds, people can know the results of an election in another country. An international football match comes into the homes of everyone with a television set. News of a disaster such as an earthquake or a flood can bring help from distant countries within hours. Help is on the way. Because of modern technology like the satellites that travel around the world, information travels fast. How has this speed of communication changed the world? To many people, the world has become smaller. Of course this does not mean that the world is actually physically smaller. It means that the world seems smaller. Two hundred years ago, communication between the continents took a long time. All news was carried on ships that took weeks or even months to cross the ocean. In the seventeenth and eighteenth centuries, it took six weeks for news from Europe to reach America. This time difference influenced people's actions. For example, one battle, or fight, in the War of 1812 between England and the United States could have been avoided. A peace agreement had already been signed. Peace was made in England, but the news of peace took six weeks to reach America. During these six weeks, the large and serious Battle of New Orleans was fought. Many people lost their lives after a peace treaty had been signed. They would not have died if news had come in time. In the past, communication took much more time than it does now. There was a good reason why the world seemed so much larger than it does today. Question: From the passage we learn that _ . - the world now seems smaller because of faster communication - the world is actually smaller today - the world is changing its size - the distance between England and America has changed since the War of 1812
the world now seems smaller because of faster communication

Q: Read the following article and select the best answer. Article: New Zealand Education Compulsory Education Compulsory education starts at age 5 and ends at age 16. Class Size The number of students in a class is 30 students. Classrooms Students from Years 5-8 stay in the same classroom for most subjects and move to other classrooms only for specific subjects. In Year 9, students take some courses With their homeroom class and some _ classes with students from different classes. Starting from Year 10, students no longer stay in the same classroom most of the time. They go to different classes according to their own choices and abilities. Term Dates A school year starts in January and ends in December. There are four terms in a year. Each term is about 10 weeks. Class Schedule School starts at around 8:30 and ends at 15:15. There are only five periods a day and a period is about an hour long. In the morning, around 10:30, there will be a 20-minute break when students usually have some snacks during this time. There is a lunch period at around 12:40 for about an hour. Teachers Teachers have to teach students of different year level at the same time. Most teachers teach students from at least three to four different year levels. Besides, quite a number of teachers teach more than one subject. This is because the fact that many courses are optional. Question: According to the passage, why can many teachers teach more than one subject? - Because many courses are optional. - Because there are not enough classrooms. - Because many of the subjects are too easy. - Because the teachers are more than enough.
A: Because many courses are optional.

Read the following article and select the best answer. Article: Learning a second language can improve brain power, scientists believe. US researchers from Northwestern University say bilingualism is a form of brain training -- a mental "work out" that adjusts the mind finely. Speaking two languages well affects the brain and changes how the nervous system reacts to sound, lab tests showed. Experts say the experiment performed by the National Academy of Sciences provides "biological" evidence of this. In an attempt to prove the guess that speaking two languages is good for one's mind, the team monitored how the brain of 48 healthy student volunteers reacted to different sounds. Twenty three of these volunteers were bilingual. The scientists used special equipment to trace the pattern of brainwaves. Under quiet, laboratory conditions, the bilingual students responded in a similar way to the English-only-speaking students, who formed the control group. But the bilingual group were far superior at processing sounds even when there were a lot of people talking in the room. They were better able to focus on to the important information -- the speaker's voice -- and block out other _ noises. Prof Nina Kraus, who led the research, said: "The bilingual's better experience with sound results in a hearing system that is highly efficient, flexible and focused in its automatic sound processing, especially in challenging or novel listening conditions." Co-author Viorica Marian said: "People do crossword puzzles and other activities to keep their minds sharp. But the advantages we've discovered in double language speakers come automatically simply from knowing and using two languages.'' Musicians appear to gain a similar benefit when rehearsing , say the researchers. According to some theories, being bilingual might help avoid dementia . Question: What conclusion could be drawn from the passage? - Being bilingual strengthens brain power. - Speaking a second language can change your nervous system. - Bilingual musicians perform better on stage. - The English-only-speaking students can concentrate easily.
(Answer)
Being bilingual strengthens brain power.
