Logical reasoning — “Most” versus “All” (choose the statement that must be true) Facts: Most stuffed toys are stuffed with beans. There are stuffed bears and there are stuffed tigers. Some chairs are stuffed with beans. Which statements must also be facts? I: Only children's chairs are stuffed with beans. II: All stuffed tigers are stuffed with beans. III: Stuffed monkeys are not stuffed with beans.

Introduction / Context:
This question probes understanding of quantifiers like “most,” the difference between existence and universality, and the danger of assuming properties for specific subtypes without evidence.

Given Data / Assumptions:

• “Most stuffed toys … beans” means more than half of stuffed toys have bean filling; not all.
• We know stuffed bears and stuffed tigers exist.
• Some chairs (unspecified type) are stuffed with beans.

Concept / Approach:
We cannot jump from “most toys have beans” to “all stuffed tigers have beans.” Nor can we restrict bean-stuffed chairs to children's chairs without evidence. Claims about stuffed monkeys are unsupported.

Step-by-Step Solution:

Verification / Alternative check:
Construct two worlds: (A) All tigers have beans; (B) No tigers have beans. Both are compatible with “most toys have beans” as long as most toys overall do. Hence II is not a must. Similar reasoning dismisses I and III.

Why Other Options Are Wrong:

• I only / II only / II and III only / I and III only: Each relies on information not given or overgeneralizes “most” to “all.”

Common Pitfalls:
Confusing “most” with “all,” and importing assumptions about specific subtypes without textual support.

Final Answer:
None of the statements is a known fact.
