• Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

  The official residence of the president of the United States is the White House, located at 1600 Pennsylvania Avenue, in Washington, D.C. The Commissioners of the District of Columbia held a meeting in 1792 and decided to hold a contest for the best design for the Presidential House. James Hoban, an architect born in Ireland, was the winner. His bid for the construction of the mansion asked for $200,000, but the final cost of the building came to twice that amount. The work on the project began during the same year, and the grounds of approximately one and a half miles west of the Capitol Hill were chosen by Major Pierre-Charles L’Enfant, who was in charge of city planning. However, the construction continued for several more years, and George Washington had stepped down as president before the building was habitable. When John Adams, the second president of the United States and his wife Abigail moved in 1800, only six rooms had been completed.

  The grey sandstone walls of the house were painted white during construction, and the color of the paint gave the building its name. The building was burned on August 24, 1814, and James Hoban reconstructed the house for President James Monroe and his family, who moved there in 1817. The north portico was added to the building in 1829, water pipes were installed in 1833, gas lighting in 1848, and electricity in 1891. In 1948, inspectors announced that the building was so dilapidated that it was beyond repair and suggested that it was cheaper to construct a new one than repair the existing dwelling. However, the national sentiment was to keep the original form intact, and Congress appropriated $5.4 million dollars for repairs. In 1961, Jacqueline Kennedy launched a program to redecorate the rooms and appointed a Fine Arts Committee to make choices of furnishing and colors.

  The house of the president accords its residents a great deal of space. The living quarters contain 107 rooms, 40 corridors, and 19 baths. The White House contains a doctor’s suite, a dentist’s office, a large solarium, a broadcasting room, and a two-floor basement for storage and service rooms. The office in which the president works is not located in the White House, but in a separate building called the West Wing. The White House stands on 16 acres of parklike land and overlooks a broad lawn, flower gardens, and wood groves.

  FIRST TIME IN THE AIR

  When John Mills was going to fly in an airplane for the first time, he was frightened. He did not like the idea of being thousands of feet up in the air. "I also didn't like the fact that I wouldn't be in control," says John.

  "I'm a terrible passenger in the car. When somebody else is driving, I tell them what to so. It drives everybody crazy."

  However John couldn't avoid flying any longer. It was the only way he could visit his grandchildren in Canada.

  "I had made up my mind that I was going to do it, I couldn't let my son, his wife and their three children travel all the way here to visit me. It would be so expensive for them and I know Tom's business isn't doing so well at the moment - it would also be tiring for the children - it's a nine-hour flight!" he says.

  To get ready for the flight John did lots of reading about airplanes. When he booked his seat, he was told that he would be flying on a Boeing 747, which is better known as a jumbo jet. "I needed to know as much as possible before getting in that plane. I suppose it was a way of making myself feel better. The Boeing 747 is the largest passenger aircraft in the world at the moment. The first one flew on February 9th 1969 in the USA. It can carry up to 524 passengers and 3.400 pieces of luggage. The fuel for airplanes is kept in the wings and the 747's wings are so big that they can carry enough fuel for an average car to be able to travel 16,000 kilometers a year for 70 years. Isn't that unbelievable? Even though I had discovered all this very interesting information about the jumbo, when I saw it for the first time, just before I was going to travel to Canada, I still couldn't believe that something so enormous was going to get up in the air and fly. I was even more impressed when I saw how big it was inside with hundreds of people!"

  The biggest surprise of all for John was the flight itself. "The take-off itself was much smoother than I expected although I was still quite scared until we were in the air. In the end, I managed to relax, enjoy the food and watch one of the movies and the view from the window was spectacular. I even managed to sleep for a while!

  "Of course," continues John, "the best reward of all was when I arrived in Canada and saw my son and his family, particularly my beautiful grandchildren. Suddenly, I felt so silly about all the years when I couldn't even think of getting on a plane. I had let my fear of living stop me from seeing the people I love most in the world. I can visit my son and family as often as I like now!"

  How did John feel about his fears in the end?

  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.

  Which of the following is NOT mentioned in the passage as a substitute for money during the colonial period?
