Read the following article and select the best answer. Article: Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod. For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer. Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish's blood and measured its freezing point. The fish were taken from seawater that had a temperature of -1.88degC and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05degC. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture. The scientists' next research job was clear: Find out what in the fish's blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When _ was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point. Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP. Question: What is the text mainly about? - The terrible conditions in the Antarctic. - A special fish living in freezing waters. - The ice shelf around Antarctica. - Protection of the Antarctic cod.
A special fish living in freezing waters.

Read the following article and select the best answer. Article: As people in China celebrated Singles' Day on November 11, the media eagerly discussed why so many marriageable young people fail to find their other half. While single people in China are pitied, their counterparts in some Western countries feel they are being discriminated against. In the US, where more than a quarter of all households consists of one person, single people often pay more insurance than married people. They don't get the same tax breaks and they seldom get promoted at work. There seems to be a bad name attached to their status - somehow their personality is flawed and therefore they are not to be trusted. Activities have created the term "singlism" to describe discrimination against unmarried people. It means stereotyping , stigmatizing and discrimination against those who are single. Globally, the number of people living alone is skyrocketing. Many people are at peace with being single and some even choose to remain single. But why are so many of us worried about singledom? Michael Cobb, professor of English at the University of Toronto in Canada, says that pop culture is to blame for people's fear of singledom. His book Single: Arguments for the Uncoupled is a critical examination of singleness in favor of the couple, making singletons one of the most despised sexual minorities in Western countries. In pop culture, singles are viewed as immature, whereas fully adults are able to form relationships and live meaningful lives. The overall message is clear: go ahead and be yourself, but if you want real happiness, make sure you get coupled up. You may get that idea from US comedy series Sex and the City and the most recent Girls, or UK's Bridge Jones' Diary. Question: According to the passage, which of the following statements is NOT true? - Half of the people in the US remain single. - Getting coupled up can help to live more happily. - Pop culture is against singleness and in favor of the couple. - The number of single people is increasing sharply in the world.
(Answer)
Half of the people in the US remain single.

Ques: Read the following article and select the best answer. Article: Environmental activists in South Korea are condemning a government plan to hunt endangered whales for scientific research. They believe the plan is part of an effort to restart commercial whaling activities. Such activities are banned in many countries. South Korea announced the proposal in July at a meeting of the International Whaling Commission in Panama. The head of the South Korean delegation said the plan was needed to answer questions about minke whale populations. He said the hunt would take place near the South Korean coast. But he did not say how many of the animals would be caught. The International Whaling Commission has yet to make a decision on the South Korean plan. The organization banned commercial whaling in 1986 because of concerns about the survival of whale species. But now, some South Korean fishermen say they are facing a threat from minke whales. They say these animals are eating what would have been their catch. The plan was immediately condemned by anti-whaling nations. Wildlife activists also criticized the proposal. Han Jeong-hee works in Seoul for the environmental group Greenpeace."It's really regretful to hear that the South Korean government is, like, considering conducting scientific whaling. Scientific whaling is just, like, thinly disguised commercial whaling. And, you know, we are of course against all commercial whaling. Japan's the only country that is doing scientific whaling at the moment and South Korea is just trying to follow that." Apart from the plan in South Korea, an aquarium in the American state of Georgia also wants to import eighteen beluga whales from Russia. The United States currently has 31 beluga whales. They are living in six aquariums and marine parks. Four of them are at the Georgia Aquarium in Atlanta. The Georgia Aquarium has asked the National Oceanic and Atmospheric Administration (NOAA) for permission to import the beluga whales. If it was approved, aquarium officials would send some of the animals to the other facilities. The Georgia... Question: What's Han Jeong-hee's attitude toward South Korea's proposal of doing scientific whaling? - Approving. - Negative. - Doubtful. - Neutral.
Ans: Negative.

Read the following article and select the best answer. Article: Gauri Nanda sees a wearable computer as a handbag -- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded in it. It looks, feels and weighs like your typical leather purse. That's where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf. Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle. As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse. Here's how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go. _ Indeed, more people will want to cross that bridge in the coming years -- making for a booming market for wearable computers that don't like something out of science fiction. Question: The purpose of the passage is _ . - to introduce a new kind of computer - to explain the function of computers - to compare different types of computers - to show how high technology affects our life
to introduce a new kind of computer
