Read the passage and answer the question.

Many of the generals who had fought under Washington did not believe that the 13 colonies could cooperate to form a single country without the strong leadership of a king. They approached him, saying that they would support him as King George I of the United States. Washington was dismayed at the idea, and asked the generals to promise never to mention it again. He served two terms as President and refused a third term, retiring to his farm in Virginia. When England’s King George heard that Washington had voluntarily given up the power of the presidency, he said, “If that is true, he is the greatest man in history.”

Which sentence tells us that Washington's decision was not one that people normally make?
