TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
PROBLEM: Article: Robert Spring, a 19 century forger ,was so good at his profession that he was able to make his living for 15 years by selling false signatures of Americans. Spring was born in England in 1813 and arrived in Philadelphia in 1858 to open a bookstore. At first he became rich by selling his small but real collection of early U.S. autographs . Discovering his ability at copying handwriting, he began imitating signatures of George. Washington and Ben Franklin and writing them on the title pages of old books. To lessen the chance of detection , he sent his forgeries to England and Canada for sale. Forgers have a hard time selling their products. A forger can't deal with a respectable buyer but people who don't have much knowledge in the field. Forgers have many ways to make their work look real. For example, they buy old books to use the aged paper of the title page, and they can treat paper and ink with chemical. In Spring's time right after the Civil War, Britain was still fond of the Southern states, so Spring invented a respectable maiden lady known as Miss Fanny Jackson, the only daughter of General "Stonewall" Jackson. For several years Miss Fanny's financial problems forced her to sell a great number of letters and manuscripts . Spring had to work very hard to satisfy the demand. All this activity did not prevent Spring from dying in poverty, leaving sharp-eyed experts the difficult task of separating his forgeries from the originals.
Answer: There was less chance of being detected there.

SOLUTION: Why did Spring sell his false autographs in England and Canada?

PROBLEM: Article: Seventeenth-century houses in colonial North American were simple structures that were primarily functional, carrying over traditional designs that went back to the Middle Ages. During the first half of the eighteen century, however, houses began to show a new elegance. As wealth increased, more and more colonist built fine houses. Since architecture was not yet a specialized profession in the colonies, the design of buildings was left either to amateur designers or to carpenters who were engaged in translating architectural handbooks imported from England. Inventories of libraries shows an astonishing number of these handbooks for builders, and the houses built during the eighteenth century show their influence. Nevertheless, most household architecture of the first-quarters of the eighteenth century displays a wide _ of taste and freedom of application of the rules laid down in these books. Increasing wealth and growing sophistication throughout the colonies resulted in houses of improved design, whether the material was wood, stone, or brick. New England still favored wood, though brick houses became common in Boston and other towns, where the danger of fire gave an impetus to the use of more durable material. A few houses in New England were built of stone, but only in Pennsylvania and areas nearby was stone widely used in buildings. An increased use of brick in houses and outbuildings is noticeable in Virginia and Maryland, but wood remained the most popular material even in houses built by wealthy landowners. In the Carolinas, even in closely packed Charleston, wooden houses were much common than brick houses. Eighteenth-century houses showed great interior improvements over the former ones. Windows were made larger and shutters removed. Large, clear panes replaced the small leaded glass of the seventeenth century. Doorways were larger and more decorative. Fireplaces became decorative features of rooms. Walls were made of plaster or wood. White paint began to take the place of blues, yellows, greens, and lead color1s, which had been popular for walls in the earlier years. After about 1730, advertisements for wallpaper styles in scenic patterns began to appear in colonial newspapers.
Answer: The improved design of eighteenth-century colonial houses.

PROBLEM: Article: People who daydream are often thought of in negative terms, such as being lazy or not doing what they should be doing. However, scientists who study the brain have learned many interesting things from studying the brains of daydreamers. Far from being a waste of time, recent research has shown that daydreaming is a healthy and useful activity for all of our brains. To study the brain, scientists use special devices that scan the brain and show pictures of which parts of the brain are active at certain times. When a person is daydreaming, the device will show a distinct pattern of activity in the brain called the "default" mode of thinking. In the default mode, the top or outside part of the brain is very active. Actually, several regions of the brain are interacting in this mode. Some scientists describe this mode as a time when the brain focuses on itself rather than focusing on the environment around the person. Typically, this occurs when a person is doing simple, undemanding work or performing routine actions that don't need much attention, like walking to school or cooking simple foods. People tend to daydream during such activities. The importance of daydreaming lies in developing both creative and social skills. When the mind is not engaged in dealing with one's immediate situation or problem, then it is free to wander. A time of wandering allows the mind to create things. New inventions may be imagined, or possible solutions to a problem can be planned. For example, solutions to problems in relationships with other people may spring to mind. In fact, most daydreams involve situations with others. Perhaps these are daydreams based on past memories, or daydreams of what might be in the future. In either case, daydreams help us develop the appropriate skills we can use in real interactions with others. As brain specialist Dr. Marcus Raichle of Washington University explains: "When you don't use a muscle, that muscle really isn't doing much. But when your brain is supposedly doing nothing and daydreaming, it's really doing a great amount." During the so-called "resting state" the brain isn't resting at all!
Answer: Why is daydreaming good for people?
