Which two statements are true about Gosu Enhancements?

The statement regarding the 'this' keyword being able to reference properties and methods in Gosu Enhancements is accurate. In Gosu, the 'this' keyword acts as a reference to the current instance of the object, allowing developers to access instance properties and methods that belong to that object. This capability is crucial for enhancing classes, as it enables modifications and additional functionalities to be applied in a seamless manner while still being able to utilize the existing properties and methods effectively.

Enhancements in Gosu are designed to add functionality or behavior to existing classes without modifying the original class code. While they can provide additional methods and behaviors, each entity does not necessarily need to have an enhancement, which means that the idea of mandatory enhancements actually contradicts the nature of how enhancements work in Gosu. Furthermore, enhancements can extend the functionality of an entity but are not meant to define new properties, as their primary purpose is to provide additional methods or modify existing behavior.

Therefore, the correct understanding of Gosu Enhancements emphasizes utilization of the 'this' keyword for property and method access while acknowledging that certain limitations exist regarding property definition and the need for enhancements on every entity.
