Step 1: Let’s diagram the statements:
- “Some chairs are glasses” → partial overlap between Chairs and Glasses.
- “All trees are chairs” → Trees are a subset of Chairs.
Step 2: Conclusion I: “Some trees are glasses.”
We cannot be certain about this from the given information because although Trees are part of Chairs, the portion of Chairs that are Glasses may or may not include any Trees. Hence, it does not definitely follow.
Step 3: Conclusion II: “Some glasses are trees.”
Similarly, we cannot confirm that any Glasses are Trees without more information. Hence, this also does not definitely follow.
Step 4: Since neither conclusion is guaranteed, the correct answer is $\mathbfneither\ I\ nor\ II\ follows$.
