In the provided code, which statements about the variable "ball" are true?

The variable "ball" being considered a global variable means that it is defined in a broader scope, typically outside of any function, making it accessible across different functions within the code. This allows the "ball" variable to be utilized in multiple functions, including those like "start" and "draw," without needing to be redeclared.

In programming, global variables are often useful when you need to share data across different functions or sections of your code without passing it around explicitly. This enables a consistent reference to the same "ball" variable, which can help maintain state and behavior throughout the execution of your game or animation.

Understanding the implications of scoping is crucial. If "ball" were merely a local variable, its use would be restricted to a specific function, leading to limitations on its accessibility in other areas of the code, such as drawing or updating its properties across frames or interactions. This distinction highlights the importance of variable scope in programming, especially in the context of animations and games where persistent state across different functions is often required.
