    Variables q r, s, t, u

    If u > t, r > q, s > t, and t > r, which of the following must be true?

    A. u > s
    B. s > q
    C. u > r

    Hint: There are two answers from the given three choices.

    I know that u and s are bigger than t. So, choice B is one of the answers. I also know that t is bigger than r. Since t is less than u, the other choice answer must be C.

    My answer: Choice B and C.

    Correct?

    Re: Variables q r, s, t, u

    Given:

    u > t > r

    then we may safely conclude:

    u > r

    Also:

    q < r < t < s

    Thus:

    s > q

    I don't see how we can infer A from the given information, so I agree with your conclusion.

    That's another problem in the books.
