[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns , and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half of the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern fridge, had been invented. Making an efficient icebox as not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary . The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping up the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox. But as early as 1803, and ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool. Options: A Keeping the ice from melting B Knowledge of the physics of heat. C Balance of insulation and circulation D Making efforts to reduce the use of ice Answer: C Balance of insulation and circulation Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: It was the end of the school term and my son Tom had less than three months left before he would finish his six years at high school. During this time he had developed a love for basketball. Sadly, because of my work over the last twelve months, I had only been able to attend a few of his games; however, I was determined to get to his last game for the school term. Tom's team came out in the first 10 minutes with a burst of goals that saw them leading by just over 20 points at the end of the first half. The second half changed as the other team quickly played themselves back into the game. Tom's team started to miss an increasing number of shots. It was at that point that the coach called his first time out. The noise of the spectators became quiet as the coach spoke to them. He had the team standing in a half circle, but he squatted down, looking up at them and fiving some very calm and clear instructions on what they needed to do in the last couple of minutes. As he stood up to allow the team to return to the court, I saw him give some further words of encouragement to all of them. You could see that he knew that the team was fighting to save the game and that he needed to lift them up. By squatting down he placed himself in a position where he was talking up to them, rather than down or at them, and as the players went back onto the court his words of encouragement served to lift their energy and spirits. Well, Tom's team went on to win the final by 5 points. As I drove away I thought about what can happen to us all in our everyday life. One of my favourite quotes is about the half filled glass of water --- "Is it half full or is it half empty?" Like the coach, the answer to this quote all depends on how you look at things. Options: A talk about what the players were doing wrong B make the players feel better C prevent spectators from hearing what he said D show his anger at the bad performance of the players Answer: B make the players feel better Question:

[A]: By squatting down, the coach wanted to _ .

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Looking almost as fresh as the day it was bought, this McDonald's Happy Meal is in fact a staggering six months old. Photographed every day for the past half a year by Manhattan artist Sally Davies, the kids meal of fries and burger shows no sign of mould or decomposition . In a work named The Happy Meal Project, Mrs. Davies, 54, tries to provide evidences that McDonald's food really is the worst you can put in your body. Sitting on a shelf in her apartment, Sally has watched the Happy Meal with increasing shock and even her dogs have resisted the urge to try and steal a free tasty snack. "I bought the meal on April 10 of this year and brought it home with the intention of leaving it out to see how it changed," she said. "I chose McDonald's because it was nearest to my house. The first thing that struck me on day two of the experiment was that it no longer gave out any smell. And then the second point of note was that on the second day, my dogs stopped circling the shelf it was sitting on trying to see what was up there." Expecting the food to begin moulding after a few days, Mrs Davies' surprise turned to shock as the fries and burger still had not shown any signs of decomposition after two weeks. "It was then that I realised that something strange might be going on with this food that I had bought," she explained. "The overall appearance of the food did not change as the weeks turned to months. And now, at six months old, the food is plastic to the touch. The only change that I can see is that it has become hard as a rock." As a strict vegetarian, Mrs. Davies' experiment has brought her amusement rather than fear. "Maybe I would be frightened at seeing this if I was a meat eater. Why hasn't even the bread become with mould? It is strange. Options: A In the fridge B On the shelf C In the bowl D On the roof Answer: B On the shelf Question:
