SECTION III Questions 1-10 Unlike those available for painting, the opportunities to exhibit sculpture in the United-States around the turn of the twentieth century were quite scarce. There was almost no room for sculpture at the influential Fine Arts Society's 57th Street Galleries Line in New York. As late as 1905, the Monumental News, a journal dedicated to the 5 promotion of sculpture, lamented, "Exhibitions of sculptors' works are so comparatively rare." In response to this dire predicament, (he sculptor Frederick W. Ruckstull and Charles de Kay, art editor of the newspaper The New York Times, founded the National Sculpture Society (NSS) in 1893, the first organization dedicated solely to the advancement of sculpture. 10 Incorporated in 1896 to promote sculptural production and encourage the exhibition and sale of the plastic arts, the National Sculpture Society (NSS) elected John Quincy 15 20 25 Adams Ward (1830-1910), the prestigious sculptor of public monuments, to serve as its first president, an office he held from 1893 to 1905. During the last twenty years of his life, ward dedicated much time to public and private organizations that promoted public art. To the end, he headed the NSS committee that oversaw the sculptural decoration of the Library of Congress Reading Room in Washington D.C. as well as the building and decorating of the Dewey Arch—a monument in New York to honor Admiral George Dewey. He was a champion of the City Beautiful Movement— an effort to increase the presence of urban art—and defended the central role that sculpture played in its national program. The National Sculpture Society promoted the production of sculpture by standardizing procedures for competitions, enhancing the professional status of sculptors, and encouraging commissions for American sculpture in homes, public buildings, parks, and squares. Moreover, ii included members in its organization who were not sculptors, hoping to close the gap between artists and the great body of the people, not merely well-to-do patrons, bui the working public. The NSS encouraged the commission and purchase of sculptures for both private consumption—home and garden—and for public enjoyment—parks and squares. Through this campaign, small-scale sculptures—either reductions of monumental artworks or smaller-sized originals—were brought to the attention of an interested public. 1.

Constructing the town, Pullman hoped to produce an ideal environment that would help attract workers of a superior type to [he railway car industry and retain 10 15 20 25 them. Pullman inhabitants were expected to embody values of thrift, industry, and morality. They were taught to develop propriety and good manners, cleanliness and neatness of appearance, diligence, and self-improvement through education and savings. Like the brick clock tower that dominated [he town center, Pullman kept a regulatory eye on his workers. In its first five yean, this new experiment in industrial life received little criticism, except from radical political groups. Crediting the town of Pullman with producing a new type of dependable and ambitious worker in a rationally ordered environment, reformers, at first, praised it as a successful model for modern industrial life. However, after 1885, with the high gloss of the experiment dulled, it became clear that the residents of Pullman had honest grievances about the overcharging of rent and other services. In 1893, The World's Columbian Exposition, an exhibition that aimed to promote American cultural, economical, and technological development, and in which George Pullman was a major investor, was held in Chicago. The town of Pullman became a popular tourist stop, attracting more than its share of curious travelers. There were 10,000 foreign viators-alone during the exposition year. In fact, the first Baedeker Travel Guide to the United States advised visitors to tour Pullman. Frequent trains and trolley cars connected the fairgrounds of the exposition with the town, and on several occasions, George Pullman himself guided the tours. Constructing a fantastic environment for the benefit of tourists, he made sure that any real tensions between bis office and the working inhabitants of the town were rendered invisible to the tourist gaze. 11.

They not only hide the real face of the mask wearer but they often evoke powerful emotions in the audience-danger, fear, sadness, joy. You might think, because so many things vary Line cross-culturally, that the ways in which emotions are displayed and recognized in the 5 face vary too. Apparently they do not. Recent research on masks from different cultures supports the conclusion that masks, like faces, tend to represent certain emotions in the some ways. We now have some evidence that the symbolism used in masks is often universal 10 15 20 25 The research on masks builds on work done by anthropologists, who used photographs of individuals experiencing various emotions. These photographs were shown to members of different cultural groups who were asked to identify the emotions displayed in the photographs. Emotions were identified correctly by most viewers, whatever the viewer's native culture. Coding schemes were developed to enable researchers to compare the detailed facial positions of individual portions of die face (eyebrows, mouth, etc.) for different emotions, What exactly do we do when we scowl? We contract the eyebrows and lower the comers of the mouth; in geometric terms, we make angles and diagonals on our faces. When we smile, we raise the corners of the mouth; we make it curved. Psychologist Joel Arnoff and his colleagues compared two types of wooden face masks from many different societies—masks described as threatening versus masks associated with nonthreatening functions. As suspected, the two sets of masks had significant differences in certain facial elements. The threatening masks had eyebrows and eyes facing inward and downward and a downward-facing mouth. In more abstract or geometrical terms, threatening features generally tend to be angular or diagonal and nonthrcatening features tend to be curved or rounded, A face with a pointed beard is threatening; a baby's face is not. The theory is that humans express and recognize basic emotions in uniform ways because all human faces are quite similar, skeletally and 16 Hp Group (www.hp-vietnam.com) muscularly. 21.

Natural selection has acted in a variety of ways in different species to enhance the efficacy of the behaviors, known as "flight behaviors" or escape behaviors that are used by prey in fleeing predators: Perhaps the most direct adaptation is enhanced flight speed and agility. Adaptations for speed. However, are likely to require sacrifices biter attributes, so we might expect only some species to adopt a simple fast flight strategy. Another way of enhancing the effectiveness of flight is to move in an erratic and unpredictable way. Many species, like ptarmigans, snipes, and various antelopes and gazelles, flee from predators in a characteristic zigzag fashion. Rapid unexpected changes in flight direction make it difficult for a predator to track prey. In some species, like the European hare, erratic zigzag flight might be more effective in the presence of predators that aie faster than they are and straight flight more effective against predators that are slower. One observation lhat supports this suggestion is the recorded tendency for slow-flying black-headed gulls, which are normally able to escape predators by means of direct flight, to show frequent changes in flight direction when they spot a peregrine falcon (peregrines are adept at capturing flying birds). A quite different way of enhancing escape by flight is to USB so-called "flash" behavior. Here, the alarmed prey flees for a short distance and then "freezes." Some predators are unexcited by immobile prey, and a startling flash of activity followed by immobility may confuse them. "Flash" behavior is used in particular by frogs and orthopteran insects, which make conspicuous jumps and then sit immobile. In some species, "flash" behavior is enhanced by the display of bright body markings. Good examples of insects with colorful markings are the red and yellow underwing moths. At rest, both species are a cryptic brown color. When they fly, however, brightly colored hind wings are exposed, which render the moths highly conspicuous. Similarly, some frogs and lizards have brightly colored patches or frills that may serve a 'flash" function when they move quickly, Some species even appear to possess "flash" sounds. The loud buzzing and clicking noises made by some grasshoppers when they jump may serve to emphasize the movement. 18 Hp Group (www.hp-vietnam.com) 30.

Many scientists collected information on the chemical composition, temperature, and pressure of the ocean at various depths and in different regions. The difficulty of gathering information about the ocean depths was immense. At first ii was believed that the temperatures in the depths never fell below 4 degrees Celsius, until it was shown that the figures were distorted by the effect of pressures on the thermometers. There was intensive study of tides and ocean currents; and a number of physicists examined the forces responsible for the movements of the water. For example, James Reonell provided the first accurate map of the currents in the Atlantic. Ocean, and the United Slates Coast Survey made extensive studies of the Gulf Stream. The zoologist Edward Forbes argued that no lire existed below a depth of 300 fathoms (about 600 meters) a view widely accepted until disproved by the voyage of the British research vessel HMS Challenger(1872-1876)The HMS Challenger expedition provided valuable information about the seabed, including the discovery of manganese nodules that are now being seen as a potentially valuable source of minerals. The first detailed map of the seabed was provided for the Atlantic by the American geographer Matthew F. Maury- He devised new techniques for measuring ocean depths, and his work proved of great value in laying the first transatlantic telegraph cables. He also studied global wind patterns and was able to provide sailors with guides that significantly reduced die time taken on many routes. Some oceanographers believed that the winds were responsible for producing ocean currents such as the Gulf Stream, but Maury disagreed. He argued that they were produced by changes in the density of seawater due to temperature, which Bet up systems of movement between warm and 20
