All daffodils are plants. All plants are living things. Some living things are real. Conclusions: I. All daffodils are living things. II. Some living things are flowers. III. All daffodils are real. Which conclusions follow?
Correct answer: A. Only I
- A. Only I
- B. Only I and II
- C. Only II and III
- D. All follow
Explanation
Daffodils sit inside plants and plants inside living things, so the chain gives conclusion I validly. Conclusion II introduces flowers, a term that appears nowhere in the premises, and conclusion III wrongly assumes the some living things that are real must include the daffodils. A valid conclusion may use only the terms the premises supply.

About Syllogisms
Syllogisms use categorical statements such as all, some and no to establish relationships between groups. Questions require checking whether conclusions necessarily follow from the premises, often by mental set relationships or Venn diagrams, and distinguishing valid deductions from conclusions that are merely possible.
