Let's clarify the options given and the question first:
The correct options to choose a minimum number must be:
(A) 200
(B) 4
(C) 18
(D) 10
The recommendation for water intake can vary depending on factors like climate, health, and physical activity. However, general guidelines from health authorities suggest that an average adult should aim to drink about 8 to 10 glasses of water per day to stay adequately hydrated. This is often simplified to about 2 liters or half a gallon per day.
Given the options, we can quickly eliminate the ones that are unrealistic or unnecessary for daily hydration needs. For instance:
- Option (A): 200 glasses is excessively high and impractical.
- Option (C): 18 glasses is also notably higher than recommended guidelines.
Now we compare the realistic options:
- Option (B): 4 glasses, which might be insufficient for an average adult to prevent dehydration.
- Option (D): 10 glasses, which aligns well with common recommendations for daily water intake.
Thus, the minimum number of glasses of water an older adult should drink each day to prevent dehydration fits best with:
Answer: (D) 10
