What is the minimum interval, in days, between occurrences of Test 18?

• A. 7 days
• B. 14 days
• C. 30 days
• D. 60 days

Answer: (C)

The idea being tested is how minimum spacing between recurring tests is defined in maintenance scheduling. For Test 18, the rule requires that two occurrences be at least a certain amount of time apart. That shortest allowable gap is 30 days, so you can schedule Test 18 again only after 30 days have passed since the last one. Shorter gaps, like 7 or 14 days, would break the minimum interval rule, while a longer gap, such as 60 days, would still be acceptable but isn’t the smallest possible interval. In short, 30 days is the minimum interval because it’s the shortest time that satisfies the required spacing between occurrences.
