In the American colonies, there was little money. England did not supply the colonies with coins and did not allow the colonies to make their own coins, except for the Massachusetts Bay Colony, which received permission for a short period in 1652 to make several kinds of silver coins. England wanted to keep money out of America as a means of controlling trade: America was forced to trade only with England if it did not have the money to buy products from other countries. The result during this pre-revolutionary period was that the colonists used various goods in place of money: beaver pelts, Indian wampum, and tobacco leaves were all commonly used substitutes for money. The colonists also made use of any foreign coins they could obtain. Dutch, Spanish, French, and English coins were all in use in the American colonies. During the Revolutionary War, funds were needed to finance the world, so each of the individual states and the Continental Congress issued paper money. So much of this paper money was printed that by the end of the war, almost no one would accept it. As a result, trade in goods and the use of foreign coins still flourished during this period. By the time the Revolutionary War had been won by the American colonists, the monetary system was in a state of total disarray. To remedy this situation, the new Constitution of the United States, approved in 1789, allowed Congress to issue money. The individual states could no longer have their own money supply. A few years later, the Coinage Act of 1792 made the dollar the official currency of the United States and put the country on a bimetallic standard. In this bimetallic system, both gold and silver were legal money, and the rate of exchange of silver to gold was fixed by the government at sixteen to one. The passage mainly discusses ___________.

Read the following passage and choose the best answer to each question. Madison Square Garden, a world-famous sporting venue in New York City, has actually been a series of buildings in varied locations rather than a single building in one spot. In 1873, P.T. Barnum built Barnum’s Monster Classical and Geological Hippodrome at the corner of Madison Avenue and 26th Street, across from Madison Square Park. Two years later, the bandleader Patrick Gilmore bought the property, added statues and fountains, and renamed it Gilmore’s Gardens. When Cornelius Vanderbilt bought the property in 1879, it was renamed Madison Square Garden. A second very lavish Madison Square Garden was built at the same location in 1890, with a ballroom, a restaurant, a theater, a rooftop garden, and a main arena with seating for 15,000. However, this elaborate Madison Square Garden lasted until 1924 when it was torn down to make way for a forty-storey skyscraper. When the second Madison Square Garden had been replaced in its location across from Madison Square Park, the boxing promoter Tex Rickard raised six million dollars to build a new Madison Square Garden. This new Madison Square Garden was constructed in a different location, on 8th Avenue and 50th Street and quite some distance from Madison Square Park and Madison Avenue. Rickard’s Madison Square Garden served primarily as an arena for boxing prize fights and circus events until it outgrew its usefulness by the late 1950s. A new location was found for a fourth for Madison Square Garden, a top Pennsylvania Railroad Station, and plans were announced for its construction in 1960. This current edifice, which includes a huge sports arena, a bowling center, a 5,000-seat amphitheater, and a twenty-nine-storey office building, does retain the traditional name Madison Square Garden. However, the name is actually quite a misnomer. The building is not located near Madison Square, nor does it have the flowery gardens that contributed to the original name. The main point of this passage is that Madison Square Garden ________.

Read the passage and mark A, B, C or D to indicate the correct answer to each of the questions. The history of clinical nutrition, or the study of the relationship between health and how the body takes in and utilizes food substances, can be divided into four distinct eras: the first began in the nineteenth century and extended into the early twentieth century when it was recognized for the first time that food contained constituents that were essential for human function and that different foods provided different amounts of these essential agents. Near the end of this era, research studies demonstrated that rapid weight loss was associated with nitrogen imbalance and could only be rectified by providing adequate dietary protein associated with certain foods. The second era was initiated in the early decades of the twentieth century and might be called “the vitamin period” Vitamins came to be recognized in foods, and deficiency syndromes were described. As vitamins became recognized as essential food constituents necessary for health, it became tempting to suggest that every disease and condition for which there had been no previous effective treatment might be responsive to vitamin therapy. At that point in time, medical schools started to become more interested in having their curricula integrate nutritional concepts into the basic sciences. Much of the focus of this education was on the recognition of deficiency symptoms. Herein lay the beginning of what ultimately turned from ignorance to denial of the value of nutritional therapies in medicine. Reckless claims were made for effects of vitamins that went far beyond what could actually be achieved from the use of them. In the third era of nutritional history in the early 1950’s to mid-1960’s, vitamin therapy began to fall into disrepute. Concomitant with this, nutrition education in medical schools also became less popular. It was just a decade before this that many drug companies had found their vitamin sales skyrocketing and were quick to supply practicing physicians with generous samples of vitamins and literature extolling the virtue of supplementation for a variety of health-related conditions. Expectations as to the success of vitamins in disease control were exaggerated. As is known in retrospect, vitamin and mineral therapies are much less effective when applied to health-crisis conditions than when applied to long-term problems of under nutrition that lead to chronic health problems. What does the passage mainly discuss?

In most discussions of cultural diversity, attention has focused on visible, explicit aspects of culture, such language, dress, food, religion, music, and social rituals. Although they are important, these visible expressions of culture, which are taught deliberately and learned consciously, are only the tip of the iceberg or culture. Much of culture is taught and learned implicitly, or outside awareness. Thus, neither cultural insiders nor cultural outsiders are aware that certain "invisible" aspects of their culture exist. Invisible elements of culture are important to us. For example, how long we can be late before being impolite, what topics we should avoid in a conversation, how we show interest or attention through listening behavior, what we consider beautiful or ugly. These are all aspects of culture that we learn and use without being aware of it. When we meet other people whose invisible cultural assumptions differ from those we have learned implicitly, we usually do not recognize their behavior as cultural in origin. Differences in invisible culture can cause problems in cross-cultural relations. Conflicts may arise when we are unable to recognize others’ behavioral differences as cultural rather than personal. We tend to misinterpret other people's behavior, blame them, or judge their intentions or competence without realizing that we are experiencing cultural rather than individual differences. Formal organizations and institutions, such as schools, hospitals, workplaces, governments, and the legal system are collection sites for invisible cultural differences. If the differences were more visible, we might have less misunderstanding. For example, if we met a man in a courthouse who was wearing exotic clothes, speaking a language other than ours, and carrying food that looked strange, we would not assume that we understood his thoughts and feelings or that he understood ours. Yet when such a man is dressed similarly to us, speaks our language, and does not differ from us in other obvious ways, we may fail to recognize the invisible cultural differences between us. As a result, mutual misunderstanding may arise. The word “deliberately” in paragraph 1 is closest in meaning to
