Considering the premise "Some dogs are cats," it follows that there exists at least one dog that is also a cat. However, this premise does not imply that all dogs are cats, nor that all cats are dogs. An examination of the subsequent conclusions reveals the following:- Conclusion 1: "Some cats are dogs" - This is true. The statement "some dogs are cats" logically necessitates that some cats are also dogs.- Conclusion 2: "All cats are dogs" - This is false. The premise only establishes a partial overlap, not a universal inclusion of all cats within the category of dogs.- Conclusion 3: "All dogs are cats" - This is false. The premise specifies "some dogs," not the entirety of the dog population.- Conclusion 4: "No dogs are cats" - This is false. The premise directly asserts the existence of dogs that are cats, thus refuting this conclusion.Therefore, only Conclusion 1 is valid. The correct selection is (A).
