the SW eft da al V. 閱讀測驗:9% It was time for another women's five-thousand-meter qualifying heat*. A group of seventeen female Dis runners from different countries lined up for the start of the race. The crowd in Rio's Olympic stadium cheered loudly when the starting gun went off. Charging ahead, the athletes strove for position and to stay AD at the front of the pack. Bunched tightly together, the group circled the track several times. Then, with less than half of the race to go, drama struck. New Zealand's Nikki Hamblin tripped on the heels of the Japanese runner in front of her. She crashed to the ground, unfortunately taking the American athlete, Abbey D'Agostino, down with her. The latter was the first to get up. Instead of continuing the race, D'Agostino quickly turned around to help Hamblin to her feet. She didn't even realize how seriously she had been injured since she was too concerned about the other runner. She was hardly able to stand due to the pain and fell to the ground again. Now it was Hamblin's turn to help D'Agostino up. With the crowd's encouragement, the two were able to carry on with the race despite their terrible falls. Hamblin and D'Agostino even managed to complete the event although they were far behind the eventual medal winners. Apart from receiving the 2016 Olympics Fair Play award for competing with such good spirit, both runners were also given the opportunity to run again in the five-thousand-meter finals. After all, it's not always about winning. 註:qualifying heat 資格賽 ) 31. Which of the following is NOT true about the incident? (A) It occurred in the 2016 Rio Olympics.
