1.Questions 1-9 With the onset of the Industrial Revolution, knowing the age of rocks became a necessary prerequisite to finding industrial minerals, such as coal, iron, and the other materials that fueled and sustained the great Western industrialization of the eighteenth Line and nineteenth centuries. It was in the mining regions where engineers, who needed a 5 better system for organizing the various types of rock scattered across Earth's surface, first grappled with scientific approaches to understanding the age of various rocks—and the age of Earth. They realized that if the various rock units could he dated by their relative ages, correlations among even widely separated rocks could be established and from this, some order recognized. 10 The pioneering European geologists first believed that identifying a rock's type would give them a strong clue to the age of the rock formation and that one of the most powerful clues came from the hardness of a given rock. Specific rock types were thus assumed to have formed at characteristically different rimes, the softest rocks having formed the most recently. This crude type of dating was first used to understand the way mountains were 15 formed, In the mid-1700's it was thought thai there were three distinct types of mountains in Europe, each formed by a different type of rock and each created at a different time. According to this theory, the oldest were the Alps, which had interior cores composed of very hard, crystalline rocks (such as granite, schist, or basalt). These mountains were called Primitive. Sitting on the flanks of the Primitive mountains were younger, smaller, 20 Secondary mountains composed of layered sedimentary rocks such as limestone. They were often rich with fossils and intermediate in hardness. The youngest Tertiary mountains were composed of softer mudstones and sandstone. Rock type, hardness, and size thus established mountain type, and rock type also became a proxy for age. However, study soon exposed the fallacy of these early notions. It was discovered that 25 some of the very high mountains were composed of the softest sediments and that even hard volcanic rock was sometimes found in very low mountains. By the early 1800's, it was understood that rock type was of no help in establishing age.

10.Questions 10-18 Some people are concerned that our soils arc becoming depleted of trace minerals by continuous agricultural use and hence that foocte are becoming depleted in vital minerals. This is a complex issue about which not a great deal is known, but the lack of evidence of Line mineral deficiencies in our population speaks to the adequacy of our soils. Furthermore, 5 soils are replenished in trace minerals by rainwater and especially by irrigation water that is obtained from rivers or wells that draw water from other soil or rock formations far away from the farm, On the other hand, agricultural practices that remove the total crop from the field year after year with no replenishment of trace minerals can over time result in a crop poor in 10 these minerals. Of course, the fanner could supply chemical fertilizer to the fields* but with most fertilizers this practice would replenish only potassium, phosphates, and nitrogen. Rotating a "green manure" crop such as clover, which is plowed under after the end of the growing season, would renew only nitrogen in the soil, not trace elements. There is a growing realization, therefore, (hat so-called organic farming makes good commercial 15 sense and would help minimize mineral depletion: Organic fanning essentially refers to farming that does not depend on chemical fertilizers; rather, soils are invigorated by applying manure and by plowing in crop wastes, such as corn stalks and bean vines, and compost. These techniques return organic material and trace minerals back to the soils and are to be commended. However, for maximum yields, a chemical fertilizer may be required 20 in addition to manure and plant waste. Some critics of modern farming methods fear that the hardier varieties of fruits and vegetables that have been developed to make shipment easier have resulted in loss of vitamin content. This concern is unfounded because the creation of vitamins by plants is an automatic biological process. Any variety of plant will make the full complement of vitamins it needs, regardless of species.

19.Questions 19-29 Animation traditionaily is done by hand-drawing or painting successive frames of an object, each slightly different than the preceding frame. In computer animation, although the computer may be the one to draw the different frames, in moat cases the artist will Line draw the beginning and ending frames and the computer will produce the drawings 5 between the first and the last drawing. This is generally referred to as computer-assisted animation, because the computer is more of a helper than an originator. In full computer animation, complex mathematical formulas are used to produce the final sequence of pictures. These formulas operate on extensive databases of numbers that define the objects in the pictures as they exist in mathematical space. The database 10 consists of endpoints, and color and intensity information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques for three-dimensional transformation, shading, and curvatures. High-tech computer animation for film involves very expensive computer systems 15 along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen, A camera can be used to film directly from the computer's display screen, but for the highest quality images possible, expensive film recorders are used. The computer 20 computes the positions and colors for ihe figures in the picture, and sends this information to the recorder, which captures it on film. Sometimes, however, the images are stored on a large magnetic disk before being sent to the recorder. Once this process is completed, it is repeated for the next frame. When the entire sequence has been recorded on the film, the film must be developed before the animation can be viewed. If the entire sequence does 25 not seem right, the motions must be corrected, recomputed, redisplayed, and rerecorded. This approach can be very expensive and time consuming. Often, computer-animation companies first do motion tests with simple computer-generated line drawings before selling their computers to the task of calculating the high-resolution, realistic-looking images.

30.Questions 30-39 The first Europeans in the Delaware Valley, a region located near die Atlantic Coast of North America, were Scandinavians. They came to the short-lived colony known as New Sweden, founded in 1638, Loose organization and local autonomy fostered a cultural Line fusion between native and settler cultures that proved one of the most notable—and least 5 understood—developments of early North American history. The Native Americans were both fanners and hunters; Native American women farmed gardens of corn, beans, and squash, while Native American men hunted for furs, hides, and meat. Such a gender division of labor was much like that practiced by Scandinavian settlers. In the harsh environment of northern Europe, Scandinavian women had been accustomed to practicing 10 forms of shifting cultivation, and they immediately understood Native American horticulture. Colonial women of the Delaware valley quickly adopted the crops of the Native American women, while Native American women welcomed European tools, such as metal hoes, and farm animals, such as pigs and chickens. Similarly, Scandinavian men quickly adapted to hunting in North America, In France 15 and England, unlike Scandinavia, hunting had been long reserved for the nobility, and so few French and English settlers had much experience in handling firearms or understanding the patterns of game animals. But Scandinavian men were familiar with hunting and receptive to learning the hunting methods of the local Native Americans. In turn Native Americans readily incorporated European steel knives, firearms, and linen 20 hunting shirts into their hunting routines. The most common symbol of pioneer North America, the log cabin, emerged in the Delaware Valley, and ought to serve as a symbol of this composite culture. Construction with logs was a tradition brought to North America by Finnish settlers of New Sweden, It was quickly picked up by other settlers, for with the resources of the American woods, 25 a few tools, and a little training, several men could erect a rough shelter in a day, or a solid house in a week, What is truly fascinating is that Native Americans quickly learned these construction techniques and probably did as much as colonists to spread the practice of log construction across the frontiers of colonial North America.

40.Questions 40-50 At the turn of the twentieth century, Americans who wished to travel between cities either for work or for pleasure had limited options. The steam railroad offered the best, the most reliable and the fastest means of transport. Electric railways (trams and trolleys) Line provided reasonable intraurban and short-distance intercity travel They also offered some 5 longer routes, but only in certain parts of the country. Horse-drawn coaches were neither a competitive nor a comfortable alternative given the deplorable slate of the nation's highways; and though bicycles were popular in both town and country, they, too, were hampered by poor road surfaces. It took the mass production and ownership of cars, together with increased attention to road construction, to bring the major breakthrough 10 in travel in the 192Q*s. And alongside the rapid spread of the popular and individualistic auto came the slower, but significant, growth of bus transport. Not only did buses largely replace trams and trolleys in urban mass transit, they also opened up new avenues of intercity travel both to those Americans who couH not afford cars and to those car owners who preferred to leave distance driving to others. 15 No particular date marks the beginning of the American intercity bus industry because so many individuals were attracted to it at about the same time by the large profits available to those who could cany fare-paying passengers over public highways- These ubiquitous bus pioneers came from all walks of life. Few knew much about transport or about business, but they were willing to take a chance on a new venture that had low entry 20 costs. Frequently driving used vehicles, these drivers concentrated on local services operated on a consumer-demand basis with the driver taking cash fares. There were no formal schedules or routes. People became aware of the new service by word of mouth or newspaper advertisements, but a regular commitment was not guaranteed. Bus drivers frequently did not start until they Had a full load; and those who traveled on the early buses were content with reaching iheir destination rather than enjoying a fast or comfortable journey.
