Answer:
The variable "hardness" is limited to the "pencil" class
Step-by-step explanation:
As we can see in the program - the line where the variable "hardness" is declared and defined is set under the instruction "class pencil:" which is the python syntax keyword for defining a class
Python uses indentation as a way of declaring scopes and in your example no indentation is used, that's why I'm making an assumption "pencil" belongs to class "pencil".
Next time please use indentation. :))
