Ques:I'm taking a test and have to guess the right answer to the question after the article. Article: Imagine being a crew member, hundreds of years ago, sailing in southern waters. Your captain is searching for food while exploring unfamiliar waters. Your job is to watch the sea off the ship's side for ice. The wind is cold on your face. Alongside the ship, a fish darts past. Another slows to a stop and raises its head above the water to look at you. How could a fish do that? Did the sailors see fish with feathers or swimming birds? Today, we know that the sailors saw birds that developed the ability to swim. Their wings became flippers, and they could "fly" through the water with amazing speed. There are many types of penguins. Only two kinds raise their young on the continent of Antarctic. Adelie penguins grow up to 29 inches tall and have a white ring around each eye. Emperor penguins have yellow orange color near their necks. Standing about 35 inches tall, they are the tallest penguins living today. Emperor penguins have nests on top of their feet. Father Emperor penguins keep the egg on top of their feet for more than two months, until the egg is ready to hatch. The mother penguin goes out for food during that time. Imagine holding an egg on your feet for two months until someone returns with food! Male and female penguins are both good parents. Once the chicks hatch, both parents travel long distances to find food for them in the sea. It may be days before the parents return and the chicks eat again. When they return with food, the fun really begins. Chicks chase their parents, begging for food. Penguin chicks eat huge amounts at one time. Eventually, the adult penguins stop feeding the chicks. This is nature's way of forcing children to grow up. When the penguin chicks are hungry enough, they find their way to the sea. Without any swimming lessons, they make their way into the icy waters and swim as only penguins do. Question: We now know that penguins seen by the sailors hundreds of years ago were  _  . Options: A: fish with the ability to fly B: birds that had learned to swim C: birds that could fly into the sea D: fish with black and white feathers

Ans:B

Ques:I'm taking a test and have to guess the right answer to the question after the article. Article: I have been very lucky to have won the Nobel Prize twice. It is, of course, very exciting to have such an important recognition of my work, but the real pleasure was in the work itself. Scientific research is like an exploration of a voyage of discovery. You are continually trying out new things that have not been done before. Many of them will lead nowhere and you have to try something different, but sometimes an experiment does work and tells you something new and that is really exciting. However small the new finding may be, it is great to think " I am the only person who knows this" and then you will have the fun of thinking what this finding will lead to and deciding what will be the next experiment. One of the best things about scientific research is that you are always doing something different and it is never boring. There are good times when things go well and bad times when they don't. Some people get discouraged at the difficult times but when I have a failure, my policy has always been not to worry but to start planning the next experiment, which is always fun. It is very exciting to make a new discovery. Some people will do the strangest things for this excitement, such as going round the world in a balloon or walking to the North Pole. There are not many new places to explore but there is a lot of new information to be discovered in science and a journey into this unknown area can be much more worthwhile and just as exciting. I am sometimes asked, "What do you have to do to win a Nobel Prize?" My answer is: "I don't know. I have never tried." But I know of one way not to win one. There are some people whose main reason for doing science is to win prizes and they are always thinking about how to do it. Such people don't succeed. To do good science you must be interested in it and enjoy doing experiments and thinking out problems. And, of course, you must be prepared to work hard and not to be too discouraged by failure. Question: In the writer's eyes his greatest pleasure in all his lifetime is   _  . Options: A: to win the Nobel Prize for the first time B: to be awarded the Nobel Prize for the second time. C: in the work itself D: to have a much more important recognition of his work.

Ans:C

Ques:I'm taking a test and have to guess the right answer to the question after the article. Article: In 1939 two brothers, Mac and Dick McDonald, started a drive-in restaurant in San Bernardino, California. They carefully chose a busy corner for their location. They had run their own businesses for years, first a theater, then a barbecue restaurant, then another drive-in. But in their new operation, they offered a new, shortened menu: French fries, hamburgers, and sodas. To this small selection they added one new idea: quick service,no waiters or waitresses, and no tips. Their hamburgers were sold for fifteen cents. Cheese was another four cents. Their French fries and hamburgers had a remarkable uniformity , for the brothers had developed a strict routine for the preparation of their food, and they insisted on their cooks' sticking to their routine. Their new drive-in became surprisingly popular, particularly for lunch. People drove up by the hundred during the busy noontime. The self-service restaurant was so popular that the brothers had allowed ten copies of their restaurant to be opened. They were content with this modest success until they met Ray Kroc. Kroc was a salesman who met the McDonald brothers in 1954 when he was selling milkshake-mixing machines. He quickly saw the special attraction of the brothers' fast-food restaurants and bought the right to franchise other copies of their restaurants. The agreement included the right to duplicate  the menu, the equipment, even their red and white buildings the golden arches . Today McDonald's is really a household name. In 1976, McDonald's had over$1 billion in total sales. Its first twenty-two years is one of the most surprising successes in modern American business history. Question: The passage suggests that   _  . Options: A: creativity is an important element of business success B: Ray Kroc was the close partner of the McDonald brothers C: Mac and Dick McDonald became broken after they sold their ideas to Ray Kroc D: California is the best place to go into business
