[EX Q]: 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.
[EX A]: What's the passage mainly about?

[EX Q]: Article: Although man has known asbestos for hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H.W.Johns, owner of a New York City Supply Shop for roofers,was responsible for the opening of that first mine. Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves,which looked much like ordinary work gloves,he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increased business in asbestos roofing materials. However,because it was very expensive to transport them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein, in the province of Quebec in Canada. Ever since 1881 Quebec has led the world in the production of this unusual mineral,which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated,a strange thing happens; the rock breaks down into fine, soft, soapy fibers. Scientists do not know why the rock can be separated easily into threads ,but they have found thousands of uses of this fireproof material, of the so- called "cloth of stone."
Answer: A new roofing material
[EX A]: Which title best expresses the main idea of this passage?

[EX Q]: Article: Freezing weather can mean frostbite and _ unless a person is prepared. Do you know how to stay warm, dry and safe in such cold winter? Frostbite is damage that happens when skin is exposed to extreme cold for too long. It mainly happens on the hands, feet, nose and ears. People with small cases of frostbite that affect only the skin may not suffer any lifelong damage. But if deeper tissue is affected, a person is likely to feel pain every time the area gets cold. If blood vessels are damaged, people can suffer an infection of gangrene . Sometimes, doctors have to remove frostbitten areas like fingers and toes. Hypothermia happens when the body cannot produce as much heat as it releases. The condition comes on slowly. Signs of hypothermia include uncontrollable shaking, very slow breathing and unclear thinking. If not treated properly, Hypothermia can be deadly. A simple way to avoid cold-related injuries is to remember four basic steps. Think of COLD -- C.O.L.D. The C stands for cover. Wear a hat and a scarf to keep heat from escaping through the head, neck and ears. And wear mittens instead of gloves. In gloves, the fingers are separated, so the hands might not stay as warm. The O stands for overexertion . Avoid activities that will make you sweaty. Wet clothes and cold weather are a bad mix. L is for layers. Wearing loose, lightweight clothes, one layer on top of another, is better than wearing a single heavy layer of clothing. Also, make sure outerwear is made of material that is water-resistant and tightly knit. Can you guess what the D in C.O.L.D. stand for? D is for dry. In other words, stay as dry as possible. Pay attention to the places where snow can enter, like the tops of boots, the necks of coats and the wrist areas of mittens. And here are two other things to keep in mind -- one for children and the other for adults. Eating snow might be fun but it lowers the body's temperature. And drinking alcohol might make a person feel warm. But what it really does is weaken the body's ability to hold heat.
Answer: They can protect us from injuries completely.
