Read the following passage and mark the letter A, B, C or D on you answer sheet to indicate the correct answer to each of the questions. 

      Glaciers are large masses of ice on land that show evidence of past or present movement. They grow by the gradual transformation of snow into glacier ice. A fresh snowfall is a fluffy mass of loosely packed snowflakes, small delicate ice crystals grown in the atmosphere. As the snow ages on the ground for weeks or months, the crystals shrink and become more compact to form firm, a much whole mass becomes squeezed together into a more dense form, granular snow. As new snow falls and buries the older snow, the layers of granular snow further compact to form firm, a much denser kind of snow, usually a year or more old, which has little pore space. Further burial and slow cementation- a process by which crystals become bound together in a mosaic of intergrown ice crystals- finally produce solid glacial ice. In this process of recrystallization, the growth of new crystals at the expense of old ones, the percentage of air is reduced from about 90 percent for snowflakes to less than 20 percent for glacier ice. The whole process may take as little as a few years, but more likely ten or twenty years or longer. The snow is usually many meters deep by the time the lower layers are converted into ice. 

      In cold glaciers those formed in the coldest regions of the Earth, the entire mass of ice is at temperatures below the melting point and no free water exists. In temperate glaciers, the ice is at the melting point at every pressure level within the glaciers, and free water is present as small drops or as larger accumulations, in tunnels within or beneath the ice. Formation of a glacier is complete when ice has accumulated to a thickness (and thus weight) sufficient to make it move slowly under pressure, in much the same way that solid rock deep within the Earth can change shape without breaking. Once that point is reached, the ice flows downhill, either as a tongue of ice filling a valley or as thick ice cap that flows out in directions from the highest central area where the most snow accumulates. The up down leads to the eventual melting of ice. 

 Which of the following does the passage mainly discuss?

     Cultural characteristics influence what is appropriate and effective communication within the classroom. That is, culture shapes what is considered to be desirable and undesirable classroom behaviors. From the expectations for students interacting with their teachers, to the manner in which they relate with one another, to the language and topics considered appropriate for teachers and students to discuss, to the overall structure of interaction within a classroom - culture affects perceptions of competent classroom interaction. 

     Students from collectivistic cultures, such as those of Japan, Korea, and China, are generally more accepting of messages about appropriate classroom behaviors and will comply with teachers' requests about classroom management. Even the nature of teachers' persuasive messages differs across cultures. Chinese college teachers, for instance, appeal to the group in gaining student compliance, whereas European American teachers, with a cultural preference for individualism, stress the benefit to the specific student. 

     Classroom displayed and participation also vary greatly across cultures. Donal Carbaugh, who studies how culture is displayed in people's conversations, makes a comparison between European American expectations for classroom interaction and those of the Blackfeet, one of the Native American tribes in the United States. It is easy to imagine a classroom with a European American teacher and students from both cultures; the European American students would, in all likelihood, feel much more comfortable and would thus have a better learning experience. Similarly, many Native American and Asian American students are unwilling to volunteer, speak out, or raise problems or concerns unless the teacher specifically calls on them by name. Korean students, for instance, are often unwilling to talk with their teachers even when the teachers have incorrectly calculated the students' scores on an exam. Questions for clarification are rarely asked of the teacher directly; to do so might be regarded as a challenge to the teacher's authority and could threaten her or his face should the answer not be known. 

     Students from many cultures who go to school in the United States sometimes find it difficult to adapt to the verbal style expected of them. Conversely, when U.S. students study overseas, they often experience similar difficulties in understanding the cultural expectations related to the educational context. Yet a willingness to speak in class is a communication characteristic highly valued by European American teachers and students, whose cultural framework celebrates individual achievement and responsibility. However, to students from cultures that emphasize the collective good and the maintenance of face, such behaviors in the classroom are too competitive, as they disrupt the group's harmony and separate people from one another. 

Which best serves as the title for the passage?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks.

     Social distancing is the public health practice of encouraging people to keep their physical distance from each other during disease (24) ________ in order to slow the spread of infection. The purpose of social distancing is to reduce the spread of influenza and to lessen the impact on society and especially on the medical care system. (25) ________, it may enable some people to avoid infection until a vaccine is available. If you are sick with the influenza pandemic, the best way to keep it from spreading is to stay home because of the following reasons. During a pandemic, everyone is susceptible to pandemic influenza and you could then transmit it to others more vulnerable than you. Small groups are better than big groups because they (26) ________ the risk of exposure. Contaminated surfaces can transmit the influenza virus for 24 hours. People may not show signs and could be contagious. You can be contagious 24-48 hours before illness onset. People are the most contagious when they are ill. Social distancing slows and decreases transmission of influenza, (27) ______ limits the effects on individuals plus schools, workplaces and the health care system. However, there are costs to this method. The costs are related to not only lost school days, missed work but also the loss of social relationships which are key to a community's resilience. When socially distancing, remember not to take it to the extreme and remove yourself from the world. You still have to participate, but do it in a safe way until the (28) _______ clears. 

their physical distance from each other during disease (24) ________ in order to slow the spread of infection.
