阅读下列短文，从每题所给的四个选项中选出最佳答案

　　Long, long ago there was no zero. To write the number sixty-three, people wrote 63. To write six hundred and three, people wrote 6 3. The space between six and three was there to mean“not any”tens. Sometimes people did not remember the space. It was hard to see and read.

　　Later people used a dot to hold the space. Six hundred and three looked like this 6.3. But the dot was hard to see. So people put a circle around it like this 6⊙3. Then people could see the dot. They remembered the space at last, only the circle around the dot was used. It was like a zero. This is one story of how the zero came to be used.
