　　题目

　　The participants in a race consisted of 3 teams with 3 runners on each team. A team was awarded 6 – n points if one of its runners finished in nth place, where 1 ≤ n ≤ 5. If all of the runners finished the race and if there were no ties, was each team awarded at least one point?

　　(1)No team was awarded more than a total of 6 points.

　　(2)No pair of teammates finished in consecutive places among the top five places.

　　选项

　　A. Statement (1) ALONE is sufficient but statement (2) ALONE is not sufficient.

　　B. Statement (2) ALONE is sufficient but statement (1) ALONE is not sufficient.

　　C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

　　D. EACH statement ALONE is sufficient.

　　E. Statements (1) and (2) TOGETHER are not sufficient.

　　答案：A

　　解析：

　　The problem indicates that 5 points were awarded for first place, 4 points for second place, 3 points for third place, 2 points for fourth place, and 1 point for fifth place, for a total of 15 points. Statement (1) indicates that no team was awarded more than 6 points. Suppose that two teams got the maximum of 6 points each, accounting for a total of 12 of the 15 points. Clearly, the third team would have gotten the other 3 points. Therefore, the answer must be A or D. Statement (2) is not conclusive. If no pair of teammates finished in consecutive order, then no team was awarded consecutive numbers of points. From this information alone, one team could have received (5 + 3 + 1) points and a second team (2 + 4) points, leaving no points for the third team; alternatively, one team could have received (5 + 2) points, a second team (3 + 1) points, leaving 4 points for the third team, etc. The best answer is A.
