The audience was amazed at his show of sportsmanship and cheered and clapped for the cyclists. After the race, Navarro said, “I didn’t want to win that way.” Later, Esteban, who won the bronze medal, tried to give his medal to Navarro. However, Navarro refused, and his response was: “Offering me the prize was worth more than what I did for him.”

Why did Navarro refuse Esteban’s medal? What did this gesture show?________________
