🎤 Model Answer spoken

This method checks whether a number is even. It takes an integer called number as input and returns a boolean value.

Inside the method, it uses the modulo operator. The expression number % 2 calculates the remainder after dividing the number by two. If the remainder equals zero, that means the number is even.

If the condition is true, the method returns true. Otherwise, it returns false. So overall, this function determines if a number is divisible by two.
