Statement Analysis:
The given statements are as follows:
1) All trees are rivers.
2) All mountains are trees.
3) All branches are mountains.
Conclusion Analysis:
We need to analyze each conclusion based on the given statements.
Conclusion 1: Some trees are branches
This conclusion can be derived from the given statements. If all branches are mountains and all mountains are trees, then some trees must be branches. Therefore, conclusion 1 follows.
Conclusion 2: Some rivers are not mountains
There is no direct information given about the relationship between rivers and mountains in the statements. Therefore, we cannot conclude that some rivers are not mountains based on the given information. Hence, conclusion 2 does not follow.
Conclusion 3: All trees are mountains
This conclusion contradicts the given statements. The statements state that all mountains are trees, but they do not mention anything about all trees being mountains. Therefore, conclusion 3 does not follow.
Summary:
Based on the analysis, we can conclude that only conclusion 1 follows from the given statements. Therefore, the correct answer is option 'A'.
