Statements:
All silk cloths are woollen cloths.
No woollen cloth is a nylon cloth.
Conclusions:
I. No silk cloth is a nylon cloth.
II. All woollen cloths are silk cloths.
Statements Analysis
We are given two statements:
- Statement 1: All silk cloths are woollen cloths. (Let Silk be S, Woollen be W. This means $S \subseteq W$).
- Statement 2: No woollen cloth is a nylon cloth. (Let Nylon be N. This means $W \cap N = \emptyset$).
Conclusion I Reasoning
Conclusion I states: No silk cloth is a nylon cloth ($S \cap N = \emptyset$).
From Statement 1, we know that the set of silk cloths is entirely contained within the set of woollen cloths ($S \subseteq W$).
From Statement 2, we know that the set of woollen cloths and the set of nylon cloths have no overlap ($W \cap N = \emptyset$).
Since all silk cloths are woollen cloths, and no woollen cloth is a nylon cloth, it logically follows that no silk cloth can be a nylon cloth. Therefore, Conclusion I is valid.
Conclusion II Reasoning
Conclusion II states: All woollen cloths are silk cloths ($W \subseteq S$).
Statement 1 says, "All silk cloths are woollen cloths" ($S \subseteq W$). This means the category 'silk' is a subset of 'woollen'. It does not state the reverse, that 'woollen' is a subset of 'silk'. For example, there could be woollen cloths that are not silk.
Therefore, Conclusion II does not logically follow from the statements.
Final Decision
Only Conclusion I logically follows from the given statements.
