Final answer:
The statement regarding daily water intake and output is false; the actual total daily water intake is around 2500 mL, and water output averages to 2.5 liters per day.
Step-by-step explanation:
The statement that total daily water intake usually ranges from 1500 to 3000 mL and total water output is 1200 to 2000 mL is false. According to the provided information, the average adult's total water output per day is approximately 2.5 liters (2500 mL), which needs to be balanced with water intake. The average adult's daily water intake is about 2500 mL from aqueous fluids, plus an additional 230 mL generated metabolically, and water gained from solid foods. Therefore, the total daily water intake typically exceeds the lower range of 1500 mL as given in the question, and the water output generally exceeds 2000 mL.
