def aunt creates a function aunt with arguments x and y and returns the value x + 2 def log creates a function log with arguments x and y and returns the product of x and y def do_twice creates a function do_twice with arguments name(a function)and x and y and returns the value defined by name function with two arguments name of x,y and log of x,y x is assigned the value 5 and y is assigned the value print(do_twice (aunt,x,y)) assigns name with aunt x with x(5) and y with y(3) name(name(x,y),log(x,y)) = aunt(aunt(5,3),log(5,3)) = aunt(7,15) = 9 So the output of the program is 9
