教教我这道题

84. Six children, Ann, Bob, Chris, Dina, Ed and Fred, are sitting at a round table. Ann is two along from Dina, who is sitting next to Fred, on his left. Also two along from Dina sits Bob, next to whom is Chris. Ann exclaims (呼喊),“Super！ I've got Chris on one side and Ed on the other.”

Answer 1

六个孩子，围坐在圆桌子边。Ann在Dina旁边两个座位，Dina坐在Fred的左边。Bob在Dina旁边两个座位，坐在Chris旁边。Ann叫到：太好了！我旁边是Chris和Ed！

先假设Dina在Ann左边第二个位子，那她右边是Fred，fred坐在Ann旁边，这与题目不符。

假设Dina在Ann右边第二个位子，那Dina右边是Fred，Bob只可能在Dina右边第二个位子，所以根据提示，从dina开始依次是Dina、Fred、Bob、Chris、Ann加上剩下的Ed。
