Number five couldn't think of a name for a while. Then time was up. He was disqualified from continuing to answer questions.
After some time, there were only two people on the stage, Sophia and Ada.
"Pythagoras," said Sophia.
"Monk Yixing," said Ada.
"Dai Xu," said Sophia.
They just met one question about this Mathematician, and Ada gave the wrong answer.
Ada was annoyed to hear the name, but she immediately thought of what she was doing. "Chen Gua," she said.
"Goldbach," said Sophia.

They did not stop until the time was up.
Ada had paused a second after contestant number three. Sophia gave twenty-one names, and Ada gave twenty. And the scores of other contestants, however, were much lower than theirs.
At the end of the round, contestant number three and number four were eliminated, leaving only four contestants on the stage.
The score gap between Sophia and Ada was still small, with only three points.
