Which statement is least consistent with the data?

• A. Sedentary 3 L/day
• B. 1-2 L/hr in hot humid environments
• C. 2 quarts per hour during hot PPE
• D. Sedentary 6 L/day

Answer: (D)

Hydration needs during live-fire training rise with sweat losses driven by heat exposure and the effort of PPE, so the data describe how replacement should scale with activity and environment rather than a fixed daily total.

The statement claiming a sedentary person would drink six liters per day is the least consistent because typical sedentary hydration is around 2–3 liters per day, even in warmer conditions. The other options align with expected patterns: replacing about 1–2 liters per hour in hot, humid environments; about two liters per hour while wearing hot PPE; and a sedate 3 liters per day fits within normal daily needs. So the six-liter-per-day figure stands out as not matching the data.
