Question 1 of 8
The use of `ABCMeta` and `@abstractmethod` enforces a class's abstract nature, preventing instantiation until the abstract methods are implemented. This ensures that subclasses adhere to a specific interface, promoting code reuse and reducing the risk of unexpected behavior. This is a core principle of abstract classes in object-oriented design.
