Question
**Question:**  
The RDA for protein recommended for a normal, healthy adult whose body weight is 180 pounds is approximately...

**Options:**

- ○ 65 grams
- ○ 85 grams
- ○ 56 grams
- ○ 112 grams

**Explanation:**

This question presents the Recommended Dietary Allowance (RDA) for protein for an adult weighing 180 pounds. The RDA for protein is typically calculated as 0.8 grams per kilogram of body weight. To find the approximate RDA for someone weighing 180 pounds, you would need to convert pounds to kilograms and apply the RDA formula.

1. **Convert 180 pounds to kilograms:**  
   - \( 180 \text{ pounds} \times 0.453592 \text{ kg/pound} \approx 81.65 \text{ kg} \)

2. **Calculate RDA for protein:**  
   - \( 81.65 \text{ kg} \times 0.8 \text{ grams/kg} \approx 65.32 \text{ grams} \)

Therefore, the closest option is 65 grams.
