Read the following article and select the best answer. Article: Masses of floating ice are so large that they dwarfs your ship, making you question whether your ship still can be spotted among such floating mountains. They are so improbable looking that you simply look in wonder. It seems that nothing that large could be natural-- and then it strikes you that something so large could only be natural. Now, people realize that as climate change is raising global temperatures, more icebergs are being born. Antarctica creates far more of them than Greenland, the source of bergs in Arctic waters. Antarctica's are also much larger, sometimes reaching the size of small countries. Recent data show the average atmospheric temperature has increased about 4.5degF in the western Antarctic Peninsula since the 1940s, making the region, among the fastest warming on earth. This jump has been shown in the recent breaking of major ice shelves along the Antarctic Peninsula. As a result, thousands of new icebergs have broken off, from ice shelves into the Southern Ocean at an accelerated rate. Even as more icebergs are being created, scientists are learning that these beauties are far from inactive masses of ice. In fact, they strikingly alter their environments biologically, chemically, and physically, making them islands of life in the open sea. Observers at sea had long remarked that they attract seals, and seabirds, and divers had noticed that fish are more numerous near them than in the surrounding sea. Now scientists are learning just what the attraction is all about. Depending on their size, location, and the season, icebergs can be nurturers or destroyers. During their existence--typically years from breaking off from an Antarctic or Greenlandic glacier to their gradual melting as they float into lower altitudes, they support animals on, around, even inside their splendid ice castle. They fertilize the ocean with nutrients, increasing sea creature production. Grounded bergs can shelter areas of the seafloor, protecting bottom-living creatures from free-floating icebergs. However,... Question: From the passage we can conclude that icebergs can _ . - preserve ocean life - carry ocean nutrients away - create a warm polar environment - keep sea animals away from polar seas
preserve ocean life

Read the following article and select the best answer. Article: Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind.How can you use this to increase your brain power? Start writing. By putting thoughts into words, you are telling yourself the logic behind what you think, feel, or only partly understand.Often, explaining a thought is the process of understanding.In other words, you increase your brain power by exercising your "explain power." Try this experiment.Explain how you'll increase your brain power, even if you have no idea how right now.Just start with anything, and create an explanation.For example, start with "I'll learn chess," or "I'll read an article on the mind every week." Explain how that will help.You'll be surprised how often this becomes a workable plan, and if you actually do this, you'll have a better understanding of your brain twenty minutes from now. Another benefit of writing is that it helps you remember.Many, if not most, highly productive people are always taking notes.You can try keeping it all in your head, but if you keep a journal of your ideas the next time you're working on a big project, you'll probably have more success. Want to understand a topic? Write a book about it.That's an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better.Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you're half-way there. Writers don't always write because they clearly understand something beforehand.Often, they write about something because they want to understand it.You can do the same.Writing will help bring you to an understanding.Give it a try. Question: What's the main purpose of the writer writing the text? - To advise readers to start their writing . - To explain the importance of writing. - To persuade readers to become writers. - To increase readers' brain power.
To advise readers to start their writing .

Q: Read the following article and select the best answer. Article: Introductory Chemistry was taught at Duke University for many years by professor Bonk. One year, two guys took the class and did pretty well on all the quizzes and mid-terms. They each had a solid A. These two friends were so confident in going into the final that the weekend before finals week, despite the Chemistry final being on Monday, they decided to go to the University of Virginia to party with some friends. They had a great time there. However, with their hangovers and tiredness, they overslept all day Sunday and didn't make it back to Duke until early Monday morning. Rather than taking the final then, they found professor Bonk after the final and explained to him how they missed the final. They told him they went up to the University of Virginia for the weekend and had planned to come back in time to study, but they had a flat tire on the way back and didn't have a spare. So they were late getting back to campus. Bonk thought this over and agreed that they could take the final the following day. The two guys, happy and relieved, studied that night and went in the next day at the time that Bonk had told them. He placed them in separate rooms and handed each of them a test booklet. He told them to begin. They looked at the first problem which was something simple about solution . It was worth 5 points. "Cool," they thought, "this is going to be an easy final". They then turned the page. They were unprepared, however, for what they saw on it. The question contained only two words: (95 points) Which tire? Question: The two guys decided to go to the University of Virginia because _ . - they were afraid of the final - there was a party there - the final would be held there - they thought they can pass the final easily
A: they thought they can pass the final easily

Read the following article and select the best answer. Article: When you want to find a job, you have to face the employer and you must know how to introduce yourself well. Then you will be lucky enough. The first impressions can play a major role in how an employer like you as a candidate . What you say during the first step of the interview may make a big difference. In fact, some hiring managers may make a decision to refuse a candidate based on what they didn't do when you met them. That's why it's important to pay attention to interview manners and to carefully think through how you will introduce yourself during a job interview. When arriving at the interview site you can introduce yourself to the receptionist by giving your name and telling the purpose of your visit. For example: "My name is Tim Jones and I have an interview scheduled with John Smith at 2 pm." You will be guided into the interview room or the hiring manager will come out to meet you in the reception area. Again, take the time to introduce yourself so the interviewer knows who you are. Offer to shake hands, even if the interviewer doesn't offer his hand first. Tell the interviewer that it is a pleasure to meet him. Smile, and be sure to make eye contact. Many hiring managers will start an interview with an open-ended question like "Tell me about yourself." Your response should focus on the key elements in your background. You should carefully analyze the job first to the interviewer, and you can point out the interests, skills, experiences, and personal qualities. Your introduction should be brief enough to hold the interest of the interviewer so that you can move on to the next question. Your goal is to connect personally with the interviewer as well as to show that you're qualified for the job. Of course, your comments should show your enthusiasm for the job and organization. However, don't overdo it and don't spend too much time talking about yourself. Question: If the interviewer doesn't offer his hand first, you should _ . - ask the interviewer an open-ended question - shake hands without looking at the interviewer - offer your hand before the interviewer - introduce yourself briefly first
