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.
For a century before the Erie Canal was built, there was much discussion among the general population of the Northeast as to the need for connecting the waterways of the Great Lakes with the Atlantic Ocean. A project of such monumental proportions was not going to be undertaken and completed without a supreme amount of effort.
The man who was instrumental in accomplishing the feat that was the Erie Canal was Dewitt Clinton. As early as 1812, he was in the nation's capital petitioning the federal government for financial assistance on the project, emphasizing what a boon to the economy of the country the canal would be; his efforts with the federal government, however, were not successful.
In 1816, Clinton asked the New York State Legislature for the funding for the canal, and this time he did succeed. A canal commission was instituted, and Clinton himself was made head of it. One year later, Clinton was elected governor of the state, and soon after, construction of the canal was started.
The canal took eight years to complete, and Clinton was on the first barge to travel the length of the canal, the Seneca Chief, which departed from Buffalo on October 26, 1825, and arrived in New York City on November 4. Because of the success of the Erie Canal, numerous other canals were built in other parts of the country.
 The Seneca Chief was         
A.the nickname of Buffalo
B.the name of the canal
C.Clinton's nickname    
D.the name of a boat

VI. Read the passage carefully, then decide whether the following statements are true (T) or false (F).
Throughout history there have been many great explorers. Have you, for example, heard of Marco Polo, the famous Italian traveler? He was the first European to travel to China. He arrived in China in the late 13th century. About 200 years later, Christopher Columbus sailed from Spain by ship. He was looking for a new way to reach India. However, as you probably know, he didn't reach India He landed in America. Five hundred years after Columbus in the' 1930s a famous explorer named Richard Byrd was one of the first persons to fly over both the North and the South Poles. Today we continue to explore this world and are studying to explore other worlds, too. In the 1930s Russian and American scientists sent many unmanned spacecraft to the moon. These spacecraft sent back very valuable information about the moon. Then on July 16th 1969 the first manned spaceship to the moon left earth. On that day Apollo 11 blasted off with three American astronauts on board. Four days after blast-off, two of these astronauts landed on the moon. They later explored the surface of the moon. About two days after landing on the moon, they started back to the earth. They arrived safely back on earth a few days later. Today we are sending unmanned spacecraft to other planets. In the future, we might walk on Mars or Venus the way we did on the moon. We might even travel to other galaxies. Who knows? One thing we know for sure is that we will continue to explore this world and other worlds, too.
