• All Book class properties visible in the diagram should be defined and set up in the constructor method.
• Implement methods:
  • can_be_archived?() in the Book class
    • should override the method from the parent class
    • should return true if parent's method returns true OR if cover_state equals to "bad"
    • otherwise, it should return false
