Step 1: Analyze the statements
- Statement 1 says no mirrors are glass, meaning mirrors and glass are completely separate sets.
- Statement 2 says no reflective objects are mirrors, meaning reflective objects and mirrors do not overlap.
Step 2: Check conclusions
- Conclusion I: "All glass are reflective"
This does not necessarily follow because the statements do not state anything about all glass being reflective.
- Conclusion II: "All reflective are glass"
This also does not follow because the statements do not provide information about the entire set of reflective objects.
Step 3: Logical reasoning
The statements only specify exclusions (no mirrors are glass, no reflective are mirrors) but do not affirm inclusions needed for either conclusion.
Hence, neither conclusion I nor II logically follows.
