(D) Rand 兰德

(E) Todd 托德

Answer

Correct choice: (B)

正确答案：（B）

Solution

Answer (B): 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.)

答案（B）：Marta 得了第 6 名，所以 Jack 得了第 5 名。因此 Todd 得了第 3 名，Rand 得了第 2 名。因为 Hikmet 比 Rand 落后 6 个名次，所以 Hikmet 得了第 8 名。（David 得了第 10 名。）
