    Let Ω p be defined as p2/3-p for all positive integers, p. If Ωn = s, and s is a positive integer, which of the following is a possible value for s?
    A

    1

    B

    3

    C

    5

    D

    6

    E

    8


    正确答案： A
    解析：
    根据题干Ωn =n2 /3-n=s. n为正整数，且s为正整数；根据函数可知只有当n是3的倍数时，s才能为整数，否则如果n2 /3不是整数，s也不是整数。现在可以从符合条件的n的最小值3代入到函数中。当n=3时，n2 /3-n =32 /3-3 = 3-3 = 0 = s；当n=6时，n2 /3-n = 62 /3-6 = 12-6 = 6 = s。所以故选D。
