In an effort to reduce plastic waste, a coffee shop replaced its plastic stirrers with wooden ones. Two months later, the total weight of waste produced by the coffee shop had not decreased. Which of the following can be most properly inferred from the information above?

✓ Correct Answer: Option B

If plastic stirrers were replaced but total waste remained unchanged, it must be that other forms of waste constitute a significant portion of the total, or that the stirrers represented a negligible amount. Option B is the most direct inference.
