Before the dragon boat competition, people made three estimates of the performance of the red, yellow, blue and green teams: (1) the blue team won the championship and the yellow team won the second runner-up; (2) the blue team won the second runner-up and the green team won Third place; (3) The red team won the second place, and the green team took the fourth place. However, the actual game results show that each of the above three estimates is half right and half wrong. From this, the order of the results of the competition is 1-4:. ['blue, green, yellow, red.', 'green, yellow, red, blue.', 'blue, red, green, yellow.', 'red, yellow, blue, green.']
