Answer
Scope determines where a variable can be accessed.
Variables declared inside a method are local to that method and cannot be accessed outside. Declaring variables with the appropriate scope ensures they are only used where needed, avoiding unintended modifications. For example, a `double discountRate` declared inside a `calculateDiscount` method is not accessible elsewhere, preventing accidental misuse.
