Understanding the Statements
The statements provided are:
- Some envelopes are gums.
- Some gums are seals.
- Some seals are adhesives.
These statements indicate relationships among four categories: envelopes, gums, seals, and adhesives.
Analyzing the Conclusions
Now, let’s analyze each conclusion based on the statements:
- Conclusion 1: Some envelopes are seals.
- This conclusion cannot be directly inferred. We know some envelopes are gums and some gums are seals, but we cannot conclude that some envelopes are seals as there may be no direct connection.
- Conclusion 2: Some gums are adhesives.
- This conclusion is also not valid. Although some gums are seals and some seals are adhesives, there is no direct indication that any gums are adhesives.
- Conclusion 3: Some adhesives are seals.
- This conclusion logically follows from the statements. Since some seals are adhesives, it is valid to say that some adhesives are indeed seals.
- Conclusion 4: Some adhesives are gums.
- Similar to conclusion 2, this cannot be concluded. There is no direct relationship established that connects adhesives to gums.
Final Evaluation
Based on the analysis:
- Valid Conclusion:
- Only conclusion 3 ("Some adhesives are seals") logically follows from the given statements.
Thus, the correct answer is option 'A' (Only 3), as it is the only conclusion that can be derived directly from the statements provided.
