The cumulative maximum DP increases with the length of the DP period (7 days: 60 hours; 14 days: 110 hours; 28 days: 190 hours).

The cumulative maximum DP increases with the length of the DP period (7 days: 60 hours; 14 days: 110 hours; 28 days: 190 hours).

• A. True
• B. False
• C. Not specified
• D. Irrelevant

Answer: (A)

The main idea to focus on is how a cumulative maximum over a period is formed. It’s the sum of the daily maximums across every day in that period. If you increase the period by adding more days, you’re adding more non-negative hours to the total, so the overall sum cannot decrease. The examples show exactly that: 7 days give 60 hours, 14 days give 110 hours, and 28 days give 190 hours. Each longer window yields a larger total, demonstrating a monotonic increase as the period length grows. So the statement is true.
