根据短文内容选择最恰当的答案。
         Benjamin Banneker was born a few months before another great American-
George Washington. Benjamin was black, but he was not a slave. He and his
mother and his grandmother were free. Benjamin's grandmother came from
England. In America she got a job and worked for many years to pay for her
boat trip across the ocean . After working many more years, she saved enough
money to buy a farm. Benjamin lived with her for a while. She taught him to read
and write and do arithmetic (算术).
         Benjamin's neighbour knew that he was clever. They were not surprised
when he built a large wooden clock. He made each piece after studying a small
pocket watch. The clock made him famous, for it was one of the first clocks built in America. People from
other places began to send hard problems of all kinds for Benjamin to settle. 
        Thomas Jefferson learned of Benjamin Banneker's ability to settle hard problems. He asked Banneker to
help build the city that was to be the capital of the United States-Washington, D.C. Banneker worked hard on
the plans for the city. He marked where the streets and buildings-the Capitol (美国国会大厦) the White House,
and many others-should be built.
        Later, L' Enfant, the Frenchman who had designed the new city, had a quarrel, and went back to France
in anger. He took all of the plans with him. The workmen couldn't build without any plans to follow.
        For a while it seemed that the plans for the capital might have to be changed, but Benjamin Banneker
remembered the plans he had helped draw. He drew each again as he had built each piece of his clock.
        If it weren't for Benjamin Banneker, Washington, D.C might look very different from the way it does
today.
