4. Which is a better estimate for the weight of an apple?
A. 12 ounces
B. 1 kilogram
Let’s think about real-world weights:
- 1 kilogram ≈ 2.2 pounds — that’s very heavy for an apple.
- A typical apple weighs around 6–8 ounces, so
12 ounces is reasonable.
- 1 kilogram is too heavy (like a large bag of apples).
✔ So,
12 ounces is a better estimate.
Answer: A. 12 ounces
