NEW QUESTION 244
The Andean cordillera is made up of many interwoven 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 greater 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 reflect 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. Much of the southern portion of the Central Andes in Bolivia is also arid. The dry season causes soil moisture deficits and diminished stream flow part of each year.
The passage mentions all the following as climatic factors in the Central Andes cordillera EXCEPT for
- A. the Pacific Humboldt current
- B. the Intertropical Convergence Zone
- C. the symmetry of the mountain ranges
- D. the rainshadow effect
- E. the southern Pacific highpressure cell
Answer: C

NEW QUESTION 247
The poet Paul Laurence Dunbar (1872-1906) was the premier Black writer of poetry that used the dialect of rural African Americans of the southern United States. Although Dunbar's works were both popular with readers and acclaimed by literary critics during his lifetime, after the First World War a radical shift occurred, at least in critical opinion of his poetry, and twentieth-century critical evaluation of his work has been generally negative. Some critics attacked his work on social grounds for failing to challenge plantation stereotypes of African Americans. Other critics, such as the poet James Weldon Johnson, argued from aesthetic grounds that dialect poetry in general was too limited as an artistic medium, and capable of producing only two effects: pathos and humor. The negative critical trend only began to reverse itself in the
1970s, when scholars began to emphasize the importance of mythic, psychological, and historical dimensions of Dunbar's works, focusing on the interior and exterior realities of African American life after the Civil War.
Which of the following general criticisms of dialect poetry is mentioned in the passage?
- A. Dialect poetry too often uses only the dialect of African Americans living in rural areas of the southern United States.
- B. Dialect poetry is highly limited in the number of artistic effects it can produce.
- C. Dialect poetry fails to represent mythic, psychological, and historical dimensions of experience.
- D. Dialect poetry has only a limited degree of popular appeal
- E. The use of dialect in poetry tends to perpetuate plantation stereotypes of African Americans.

NEW QUESTION 250
Always read the meter dials from the right to the left. This procedure is much easier, especially if any of the dial hands are near the zero mark. If the meter has two dials, and one is smaller than the other, it is not imperative to read the smaller dial since it only registers a small amount. Read the dial at the right first. As the dial turns clockwise, always record the figure the pointer has just passed. Read the next dial to the left and record the figure it has just passed. Continue recording the figures on the dials from right to left. When finished, mark off the number of units recorded. Dials on water and gas meters usually indicate the amount each dial records.
Always read the meter dials ...
- A. from the large dial to the small dial
- B. from the small to the large dial
- C. from right to left

NEW QUESTION 251
Conflict had existed between Spain and England since the 1570s. England wanted a share of the wealth that Spain had been taking from the lands it had claimed in the Americas.
Elizabeth I, Queen of England, encouraged her staunch admiral of the navy, Sir Francis Drake, to raid Spanish ships and towns. Though these raids were on a small scale, Drake achieved dramatic success, adding gold and silver to England's treasury and diminishing Spain's omnipotence. Religious differences also caused conflict between the two countries. Whereas Spain was Roman Catholic, most of England had become Protestant.
King Philip II of Spain wanted to claim the throne and make England a Catholic country again. To satisfy his ambition and also to retaliate against England's theft of his gold and silver, King Philip began to build his fleet of warships, the Armada, in January 1586.
Philip intended his fleet to be indestructible. In addition to building new warships, he marshaled one hundred and thirty sailing vessels of all types and recruited more than nineteen thousand robust soldiers and eight thousand sailors. Although some of his ships lacked guns and others lacked ammunition, Philip was convinced that his Armada could withstand any battle with England. The martial Armada set sail from Lisbon, Portugal, on May 9,1588, but bad weather forced it back to port. The voyage resumed on July 22 after the weather became more stable. The Spanish fleet met the smaller, faster, and more maneuverable English ships in battle off the coast of Plymouth, England, first on July 31 and again on August 2. The two battles left Spain vulnerable, having lost several ships and with its ammunition depleted. On August 7, while the Armada lay at anchor on the French side of the Strait of Dover, England sent eight burning ships into the midst of the Spanish fleet to set it on fire. Blocked on one side, the Spanish ships could only drift away, their crews in panic and disorder. Before the Armada could regroup, the English attacked again on August 8. Although the Spaniards made a valiant effort to fight back, the fleet suffered extensive damage.
During the eight hours of battle, the Armada drifted perilously close to the rocky coastline. At the moment when it seemed that the Spanish ships would be driven onto the English shore, the wind shifted, and the Armada drifted out into the North Sea. The Spaniards recognized the superiority of the English fleet and returned home, defeated The ____ Armada set sail on May 9, 1588.
- A. isolated
- B. independent
- C. warlike
- D. answer not available
- E. complete

NEW QUESTION 257
In the sixteenth century, an age of great marine and terrestrial exploration, Ferdinand Magellan led the first expedition to sail around the world. As a young Portuguese noble, he served the king of Portugal, but he became involved in the quagmire of political intrigue at court and lost the king's favor. After he was dismissed from service to the king of Portugal, he offered to serve the future Emperor Charles V of Spain.
A papal decree of 1493 had assigned all land in the New World west of 50 degrees W longitude to Spain and all the land east of that line to Portugal. Magellan offered to prove that the East Indies fell under Spanish authority. On September 20, 1519, Magellan set sail from Spain with five ships. More than a year later, one of these ships was exploring the topography of South America in search of a water route across the continent. This ship sank, but the remaining four ships searched along the southern peninsula of South America. Finally they found the passage they sought near a latitude of 50 degrees S Magellan named this passage the Strait of All Saints, but today we know it as the Strait of Magellan. One ship deserted while in this passage and returned to Spain, so fewer sailors were privileged to gaze at that first panorama of the Pacific Ocean. Those who remained crossed the meridian we now call the International Date Line in the early spring of 1521 after ninety eight days on the Pacific Ocean. During those long days at sea, many of Magellan's men died of starvation and disease. Later Magellan became involved in an insular conflict in the Philippines and was killed in a tribal battle. Only one ship and seventeen sailors under the command of the Basque navigator Elcano survived to complete the westward journey to Spain and thus prove once and for all that the world is round, with no precipice at the edge.
The sixteenth century was an age of great ___exploration.
- A. land
- B. mental
- C. common man
- D. cosmic
- E. none of the above
