(B) Hikmet 希克梅特

(D) Rand 兰德

(E) Todd 托德

Answer

Correct choice: (B)

正确答案：（B）

Solution

Marta finished 6th, so Jack finished 5th. Therefore Todd finished 3rd and Rand finished 2nd. Because Hikmet was 6 places behind Rand, it was Hikmet who finished 8th. (David finished 10th.)

Marta 第 6 名，所以 Jack 第 5 名。因此 Todd 第 3 名，Rand 第 2 名。因为 Hikmet 比 Rand 晚 6 名，所以 Hikmet 第 8 名。（David 第 10 名。）
