Quizplus · Accepted Answer

Alicia can create a function that contains the set of statements to make the changes, and then call the function with an event listener for the mouseover event. This way, the statements can be easily reused and referenced as a single unit. Variables and if statements are not sufficient for this task, as they do not allow for easy reusability and referencing as a single unit.
