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... Many people believe that science helps society to progress through  _ A) knowledge only. B) more than one aspect. C) technology only. D) the use of machines.

(Question)
In the next five years, STEM (science, technology, engineering and mathematics) jobs are projected to grow twice as quickly as jobs in all other fields according to the U.S. Bureau of Statistics. While all jobs are expected to grow by 10.4 percent, STEM jobs are expected to increase by 21.4 percent. By this measure, future STEM jobs represent a huge opportunity to today's students. But, in fact, of the 3.8 million ninth graders in the U.S., only 233,000 end up choosing a STEM degree in college, according to the National Center for Education Statistics. This means only 6 percent of ninth graders will become STEM graduates. And of these graduates, women will be even more underrepresented in most STEM fields. These are alarming statistics. How do we get more young boys and girls to be interested in STEM-related fields? It isn't an easy task. Schools do not always adequately prepare students for these severe subjects, and college programs are designed to get rid of those who are less persistent. Nationally, only 41 percent of initial STEM majors who begin a degree in STEM-related fields complete their degree in less than six years. In addition, social pressures continue to cast a shadow over girls who might otherwise consider the STEM fields. A couple of years ago, I met amazing parents, both of whom had a background in engineering and hoped their 10-year-old daughter would follow in their footsteps. They encouraged her to take an after-school science / robotics program. When she got there, she found she was outnumbered 6:1 by boys in the class. As the only girl, she came home crying much of the time because she was teased and told that geeky girls are not welcome in the boys' club. Ironically, by the time young boys are entering college programs in STEM fields, many complain about the lack of girls. Starting at an early age, even as young as kindergarten, we need to encourage and help the next generation leaders to consider taking up science, computing, math and technology. We also need to realize that for young... In the writer's opinion, what should we do now? A) Show the students the advantages of STEM jobs. B) Provide college graduates with more STEM jobs. C) Encourage more young children to take up STEM. D) Make people aware of the importance of STEM.

Ques: It's impossible to determine how many people would have lost their lives without the contribution of African-American inventor Dr Charles Drew. Charles Drew was born on June 3, 1904, in Washington, DC. His early interest was in education, but he was also an outstanding athlete. While in college, he was awarded as the man who contributed the most to sports during his four years in school. Drew's sister Elsie suffered from tuberculosis  and died in 1920. Her death influenced his decision to study medicine. After becoming a doctor and working as a college instructor, Drew went to Columbia University, where he earned his Doctor of Medical Science degree. During this time he became involved in research on blood and blood transfusions. At Columbia, he wrote a paper on "banked blood", in which he described a technique he developed for the long-term preservation of blood plasma. Before his discovery, blood could not be stored for more than two days because of the rapid breakdown of red blood cells. Drew had discovered that by separating the plasma from the whole blood and then refrigerating them separately, they could be combined a week later for a blood transfusion. Drew became the first African American to receive a PhD in medical science. After World War II broke out, Drew was called upon to put his techniques into practice. He was named a project director for the American Red Cross but soon quit his post after the government issued an order that blood taken from white donors should be separated from that of black donors. On April 1, 1950, after he attended the annual free clinic at the John A. Andrew Memorial Hospital, he and other three physicians decided to drive back home. As he was tired from spending the night before in the operating room, he lost control of his car. Drew was badly injured and was taken to Alamance General Hospital in Burlington, North Carolina. He was pronounced dead half an hour after he first received medical attention. Drew's funeral was held on April 5, 1950, at the Nineteenth Street... We can learn from the passage that Dr Charles Drew is best remembered by people as   _  .       . A) an outstanding athlete B) a college instructor C) a medical researcher D) a project director
Ans: C


There are many travel destinations across the globe. What confuses a person most is which travel destination to choose. When choosing a destination for a vacation or a trip, you need to decide what that destination has to offer to you. Meanwhile, you should also take many factors into consideration, so that the decision-making will get easy. The amount of money you want to spend is an important factor and plays an important role in deciding a destination. For example, cities like London, New York, Vegas etc are expensive. On the other hand when you travel to Asia, the cost is generally lower and you don't need to spend much on traveling, lodging or shopping. Therefore, it is important to estimate your budget before selecting a destination. When you plan your vacation, another important thing to plan is the number of the days you want to spend. There are many travel destinations in the world that can be covered in a week's time. Some destinations like Africa, or Maldives beaches can be planned in a week's time. Some other destinations like New York, Thailand may require more than a few weeks to enjoy completely. Vacations are also planned according to the company you have. For example, if you travel with your family, then you'll need a place where you can enjoy with your family members. Similarly, if you are going with friends, a city full of amusement parks, museums, shopping centers will be an ideal  destination. Therefore you need to consider whom you are going with, before deciding a destination. Who are the intended readers of the text?
