Statement: All flowers are beautiful. Some beautiful things are fragile. Conclusion I: Some flowers are fragile. Conclusion II: All beautiful things are flowers.
Show Hint
Avoid assuming overlaps in logical reasoning unless explicitly stated.
Step 1: Translate statements - Statement 1: “All flowers are beautiful.” In logic: All F are B (where F = flowers, B = beautiful things). - Statement 2: “Some beautiful things are fragile.” In logic: Some B are Fr (where Fr = fragile things).
Step 2: Evaluate Conclusion I - Conclusion I: “Some flowers are fragile.” In logic: Some F are Fr. From “All F are B” and “Some B are Fr,” we cannot conclude that the fragile beautiful things (B that are Fr) include flowers (F). The fragile beautiful things could be non-flowers (e.g., glass vases). Thus, Conclusion I does not necessarily follow.
Step 3: Evaluate Conclusion II - Conclusion II: “All beautiful things are flowers.” In logic: All B are F. The first statement says all flowers are beautiful (All F are B), not that all beautiful things are flowers. Many beautiful things (e.g., paintings) may not be flowers. This reverses the logic and is false. Conclusion II does not follow.
