Correct answer: A. Some birds are green
- A. Some birds are green
- B. All birds are green
- C. No bird is green
- D. All green things are birds
Explanation
The birds that are parrots must be green, so some birds are certainly green, while the other birds could be any colour. A conclusion cannot be broader than the narrowest premise supporting it. The last option reverses a universal, which is never valid.

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.
