    Consider the following Ada skeletal program:

    procedure Main is
    X : Interger;
    procedure Sub3; -- This is a declaration of Sub3
    -- It allows sub1 to call it
    procedure Sub1 is
    X : Interger;
    procedure Sub2 is
    begin -- of Sub2
    end; -- of Sub2
    begin -- of Sub1
    end; -- of Sub1
    procedure Sub3 is
    begin -- of Sub3
    end; -- of Sub3
    begin -- of Main
    end; -- of Main

    Assume that the execution of this program is in the following unit order:

    Main calls Sub1
    Sub1 calls Sub2
    Sub2 calls Sub3

    Need this explained:

    Assuming static scoping, which declaration of X is the correct one for a reference to X in the following:

    i. Sub1
    ii. Sub2
    iii. Sub3

    I call the first declaration of X in Main as outer X and the second declaration of X in Sub1 as
    the inner X.

    i. ...
