In the procedure Mystery below, the parameter number is a positive integer.

• PROCEDURE Mystery (number)
• {
•   REPEAT UNTIL (number ≤ 0)
•   {
•     number ← number - 2
•   }
•   IF (number = 0)
•   {
•     RETURN (true)
•   }
•   ELSE
•   {
•     RETURN (false)
•   }
• }

Which of the following best describes the result of running the procedure Mystery?

The procedure will repeat the process of subtracting 2 until the number is 0 or negative. For even numbers, this will always result in 0 and the procedure will therefore return true.
