Show answer & explanation
Correct answer: B
Answer: Only II follows.
Explanation:
Conclusion I: Some birds are definitely not hens. This does not follow. From the premises we know only that all birds are tall and that some tall things are hens. There is no information that guarantees any bird is not a hen; it is possible that every bird is a hen.
Conclusion II: At least some hens are tall. This follows. The statement "some talls are hens" directly asserts that there exists at least one hen who is tall, so this conclusion is definitely true.
