Final answer:
The statement refers to an event listener in programming that calls a function every time the mouse moves, commonly achieved using methods like addEventListener in JavaScript.
Step-by-step explanation:
The statement that will call the function paint every time the mouse is moved is related to an event listener in a programming context. This could refer to various programming languages, but for instance, in JavaScript, it would involve the use of the addEventListener method applied to a document object or HTML element, like so: document.addEventListener('mousemove', paint);. This adds a mouse event listener that triggers the paint function whenever the mouse moves across the area for which the event listener has been set up.
