    All good to me.

    For number 3, I am not sure if I understand the context of the question.
    I interpret it to mean what variable can adversely affect the accuracy of extrapolated data, in which case I choose independent variable. If an independent variable is chosen out of the applicable range, then the result will be doubtful.
