  1. #1 ok
    #2 no way to know.
    Knowing the average tells you nothing about the temperature range.
    All you know is that the average ranges from -11 to 22. Heck, there's no indication that these are even the extreme values! What about August? It may be hotter than July.

    Very poorly stated question.
