The Andean cordillera is made up of many inten/voven mountain ranges, which include high intermontane plateaus, basins, and valleys. The Northern Andes contain several broad ecosystems falling into four altitudinal belts. Its northern subregion is distinguished by higher humidity and by greater climatic symmetry between eastern and western flanks. The Central Andes are characterized by a succession of agricultural zones with varied climatic conditions along the mountains’ flanks and by large, highaltitude plateaus, variously called puna or altiplano, which do not occur in the Northern Andes. The soil fertility of the northern altiplano is generally good. The western Central Andean ranges are relatively arid with desert-like soils, whereas the eastern ranges are more humid and have more diverse soils. The eastern slopes of the Central Andes in many ways are similar to the wet forests of the Northern Andes. Unlike the Northern Andes, however, these slopes have a dry season. In regions of gentle topography, such as the Amazon basin, regional climatic variation can be determined from a few widely spaced measurements. Regional projections in the Andean cordillera are quite difficult by comparison. For example, while air temperature generally decreases with increasing altitude, variability of mountain topography can produce much lower than expected air temperatures. Nevertheless, some general climatic patterns are discernible. For example, with increasing distance south of the equator the seasonality of precipitation increases, whereas the total annual amount generally decreases. Humidity commonly increases with increasing altitude, but only to some intermediate altitude, above which it declines. The variability of mountain terrain also affects precipitation, such that conditions of extreme wetness and aridity may exist in close proximity. Related to this temperature gradient is a pattern of ater rainfall at the valley heads, and less rain at lower altitudes, resulting in part from mountain rainshadow effect. The weather patterns of the Andean cordillera and Amazon basin in general refilect movements of highand low-pressure cells associated with the Intertropical Convergence Zone, a low-pressure trough that moves further north and south on a seasonal basis. Precipitation is high throughout the year in the highlands and on the coast in the Northern Andes. Coastal aridity increases south of central Ecuador, culminating in the Atacama desert of northern Chile. In the Central Andes, highland precipitation is seasonal, and amounts are approximately half those measured in the Northern Andes. The aridity of the Central Andean coastal zone is the result of the drying effect of the cold Pacific Humboldt current and the southern Pacific high-pressure cell. lV|uch of the southern portion of the Central Andes in BolMa is also arid. The dry season causes soil moisture deficits and diminished stream flow part of each year. According to the passage, the northern part of the high-altitude plateaus is characterized by which of the following?
Charles in 1927. This feat, when Lindbergh was only twenty-five years old, assured him a lifetime of fame and public attention. Charles Augustus Lindbergh was more interested in flying airplanes than he was in studying. He dropped out of the University of Wisconsin after two years to earn a lMng performing daredevil airplane stunts at country fairs. Two years later, he joined the United States Army so that he could go to the Army Air Service flight-training school. After completing his training, he was hired to fly mail between St. Louis and Chicago. Then came the historic flight across the Atlantic. In 1919, a New York City hotel owner offered a prize of $25,000 to the first pilot to fly nonstop from New York to Paris. Nine St. Louis business leaders helped pay for the plane Lindbergh designed especially for the flight. Lindbergh tested the plane by flying it from San Diego to New York, with an overnight stop in St. Louis. The flight took only 20 hours and 21 minutes, a transcontinental record. Nine days later, on May 20,1927, Lindbergh took off from Long Island, New York, at 7:52 He had flown more than 3,600 miles in less than thirty four hours. His flight made news around the world. He was given awards and parades everywhere he went. He was presented with the U. S. Congressional Medal of Honor and the first Distinguished Flying Cross. For a long time, Lindbergh toured the world as a U. S. goodwill ambassador. He met his future wife, Anne Morrow, in Mexico, where her father was the United States ambassador. During the 1930s, Charles and Anne Lindbergh worked for various airline companies, charting new commercial air routes. In 1931, for a major airline, they charted a new route from the east coast of the United States to the Orient. The shortest, most efficient route was a great curve across Canada, over Alaska, and down to China and Japan. Most pilots familiar with the Arctic did not believe that such a route was possible. The Lindberghs took on the task of proving that it was. They arranged for fuel and supplies to be set out along the route. On July 29, they took off from Long Island in a specially equipped small seaplane. They filew by day and each night landed on a lake or a river and camped. Near Nome, Alaska, they had their first serious emergency. Out of daylight and nearly out of fuel, they were forced down in a small ocean inlet. In the next morning's light, they discovered they had landed on barely three feet of water. On September 19, after two more emergency landings and numerous close calls, they landed in China with the maps for a safe airline passenger route. Even while actively engaged as a pioneering flier, Lindbergh was also working as an engineer. In 1935, he and Dr. Alexis Carrel were given a patent for an artificial heart. During World War I in the 1940s, Lindbergh served as a cMlian technical advisor in aviation. Although he was a cMlian, he filew over fifty combat missions in the Pacific. In the 1950s, Lindbergh helped design the famous 747 jet airliner. In the late 1960s, he spoke widely on conservation issues. He died August 1974, having lived through aviation history from the time of the first powered flight to the first steps on the moon and having influenced a big part of that history himself. When did Charles meet Anne Morrow?
The origin of the attempt to distinguish early from modern music and to establish the canons of performance practice for each lies in the eighteenth century. In the first half of that century, when Telemann and Bach ran the collegium musicum in Leipzig, Germany, they performed their own and other modern music. In the German universities of the early twentieth century, however, the reconstituted collegium musicum devoted itself to performing music from the centuries before the beginning of the "standard repertory," by which was understood music from before the time of Bach and Handel. Alongside this modern collegium musicum, German musicologists developed the historical sub-discipline known as "performance practice," which included the deciphering of obsolete musical notation and its transcription into modern notation, the study of obsolete instruments, and the re-establishment of lost oral traditions associated with those forgotten repertories. The cutoff date for this study was understood to be around 1750, the year of Bach’s death, since the music of Bach, Handel, Telemann and their contemporaries did call for obsolete instruments and voices and unannotated performing traditions—for instance, the spontaneous realization of vocal and instrumental melodic ornamentation. Furthermore, with a few exceptions, late baroque music had ceased to be performed for nearly a century, and the orally transmitted performing traditions associated with it were forgotten as a result. In contrast, the notation in the music of Haydn and Nlozart from the second half of the eighteenth century was more complete than in the earlier styles, and the instruments seemed familiar, so no "speciaI" knowledge appeared necessary. Also, the music of Haydn and Mozart, having never ceased to be performed, had maintained some kind of oral tradition of performance practice. Beginning around 1960, however, early-music performers began to encroach upon the music of Haydn, Mozart, and Beethoven. Why? Scholars studying performance practice had discovered that the lMng oral traditions associated with the Viennese classics frequently could not be traced to the eighteenth century and that there were nearly as many performance mysteries to solve for music after 1750 as for earlier repertories. Furthermore, more and more young singers and instrumentalists became attracted to early music, and as many of them graduated from student- amateur to professional status, the technical level of early-music performances took a giant leap fonrvard. As professional early-music groups, building on these developments, expanded their repertories to include later music, the mainstream protested vehemently. The differences between the two camps extended beyond the question of which instruments to use to the more critical matter of style and delivery. At the heart of their disagreement is whether historical knowledge about performing traditions is a prerequisite for proper interpretation of music or whether it merely creates an obstacle to inspired musical tradition. Which of the following is the most appropriate title for the passage?
While there will always be a need for social programs geared toward alleviating the poverty of indMduals, the community is perhaps the more relevant level for public policy intervention, especially in rural areas. It has been recognized that social isolation within urban ghettos is a structural characteristic of urban poverty, but rural poverty is marked by physical isolation as well. This uniqueness makes rural community poverty particularly intractable, requiring policies that account for the cost of isolation. It is possible to provide vocational training for indMduals anywhere, but if there are no jobs within the community for those indMduals, the training is largely wasted. The current transition to a service-based economy and deregulation in transportation (resulting in disproportionately higher transportation costs for relatively isolated areas) have only exacerbated the growing social and economic distress in rural America, underscoring the need to redefine poverty and redirect the focus of our funding agencies and policy-makers in accordance with the new definition. What’s needed is a more holistic view on an aggregate level, where poverty is properly seen as a condition of the local social structure, with income only one of the salient parameters. The author seeks to draw which of the following distinctions between urban ghettos and impoverished rural communities?
