Problem: Write a multi-choice question for the following article: Article: There are an extremely large number of antsworldwide. Each individual ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior. In colonies that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone , chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit. In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective intelligence greater than you would expect from itsindividual parts.

A: Question: Ants can use pheromones for _ .Options:A escapeB communicationC warning enemiesD arranging laborAnswer:B

Problem: Write a multi-choice question for the following article: Article: Books are not Nadia Konyk's thing. Her mother brings them home from the library, but Nadia rarely shows interest. Instead, like so many other teenagers, Nadia, 15, is addicted to the Internet. She regularly spends at least six hours a day in front of the computer, spending most of her time reading and commenting on stories written by other users. Her mother, Deborah Konyk, would prefer that Nadia read books for a change. As teenagers' scores on reading tests have declined, some argue that the hours spent surfing the Internet are the enemy of reading--destroying a precious common culture that exists only through the reading of books. Critics have warned that electronic media would destroy reading. Others say the Internet has created a new kind of reading. The Web inspires a teenager like Nadia, who might otherwise spend most of her leisure time watching television, to read and write. What is different now, some literacy experts say, is that spending time on the Web engages viewers with text. Web supporters believe that strong readers on the Web may eventually surpass those who rely on books. Reading five Web sites, experts say, can be more enriching than reading one book. "It takes a long time to read a 400-page book," said Spiro. "In a tenth of the time," he said, the Internet allows a reader to "cover a lot more of the topic from different points of view." Some literacy experts say that reading itself should be redefined. Interpreting videos or pictures, they say, may be as important a skill as analyzing a novel or a poem. "Kids are using sound and images so they have a world of ideas to put together," said Donna Alvermann, a professor of literacy education at the University of Georgia. "Books aren't out of the picture, but they're only one way of experiencing information in the world today." Next year, the Organization for Economic Cooperation and Development, which gives reading, math and science tests to 15-year-old students in more than 50 countries, will add an electronic reading component . The United...

Problem: Write a multi-choice question for the following article: 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.
