Personal space, an updated form of Edward T. Hall’s 1966 proxemics, is the region surrounding each person, or that area which a person considers his domain or territory. Often if entered by another being without this being desired, it makes them feel uncomfortable. The amount of space a being (person, plant, animal) needs falls into two categories, individuate individual physical space (determined by imagined boundaries), and the space au individual considers theirs to live in (often called habitat). What distance is appropriate for a particular social situation depends on culture. It is also a matter of personal preference. Personal space is highly variable. Those who live in a densely populated environment tend to have smaller personal space requirements. Thus a resident of India may have a smaller personal space than someone who is home on the Mongolian steppe, both in regard to home and individual. Personal space can be determined on a habitat level by profession, livelihood, and occupation. It can also be heavily affected by a person’s position in society, with the more affluent a person being the larger personal space they demand. While it is highly variable and difficult to measure accurately the best estimates for personal physical space place it at about 24.5 inches (60 centimeters) on either side, 27.5 inches (70 centimeters) in front and 15.75 inches (40 centimeters) behind for an average westerner. In certain circumstances people can accept having their personal space violated. For instance in romantic encounters the stress from allowing closer personal space distances can be reinterpreted into emotional fervor. Another method of dealing with violated personal space, according to psychologist Robert Sommer, is dehumanization. He argues that, for instance on the subway, crowded people imagine those infiltrating their personal space as inanimate. Changing perceptions about personal space and the fluctuating boundaries of public and private in European culture since the Roman Empire have been explored in "A History of Private Life", under the general editorship of Philippe Aries and Georges Duby, published in English by the Belknap Press. "Dehumanization" in the last paragraph means ______.
A. abusing other human beings
B. being a human being
C. decreasing the nature of human beings
D. being kind to the others

In the 18th century, New York was smaller than Philadelphia and Boston. Today it is the largest city in America. How to explain the change in its size and importanceTo answer this question we must consider certain facts about geography, history and economies. Together these three will explain the huge growth of America’s most famous city.The map of the Northeast shows that four of the most heavily-populated areas in this region are around seaports. At these points materials from across the sea enter America, and the products of the land are sent there for export across the sea.Economists know that places where transportation lines meet are good places for making raw materials into completed goods. That is why seaports often have cities nearby. But cities like New York needed more than their geographical location in order to become great industrial centers. Their development did not happen simply by chance.About 1815, when many Americans from the east coast had already moved to the west, trade routes from the ports to the central regions of the country began to be a serious problem. The slow wagons of that time, drawn by horses or oxen, were too expensive for moving heavy freight very far. Americans had long admired Europe’s canals. In New York State a canal seemed the best solution to the transportation problem. From the eastern end of Lake Erie all the way across the state to the Hudson River there is a long trip of low land. Here the Erie Canal was constructed. After working for several years it was completed in 1825.The canal produced an immediate effect. Freight costs were cut to about one-tenth of what they had been. New York City, which had been smaller than Philadelphia and Boston, quickly became the leading city of the coast. In later years, transportation routes on the Great Lakes were joined to routes on the Mississippi River. Then New York City became the end point of a great inland shipping system that extended from the Atlantic Ocean far up the western branches of the Mississippi.The new railroads made canal shipping not as important as before, but it tied New York even more closely to the central regions of the country. It was easier for people in the central states to ship their goods to New York for export overseas.Exports from New York were greater than imports. Consequently, shipping companies were eager to fill their ships with passengers on the return trip from Europe. Passengers could come from Europe very cheaply as a result.Thus New York became the greatest port for receiving people from European countries. Many of them remained in the city. Others stayed in New York for a few weeks, months, or years, and then moved to other parts of the United States. For these great numbers of new Americans, New York had to provide homes, goods, and services. Their labor helped the city become great. Which of the following statements is TRUE()
A. The Erie Canal connected Lake Erie and the Hudson River.
B. Economists are of the opinion that places where farming is done are good for making raw materials into finished goods.
C. Wagons drawn by horses and oxen soon proved to be better and cheaper than canal transportation.
D. The coming of the railroads caused New York to become less important as a shipping center.
