Statements: Only graduates can apply. Sana applied successfully. Which conclusion follows?
Correct answer: A. Sana is a graduate
- A. Sana is a graduate
- B. Sana is not a graduate
- C. All graduates applied
- D. Nothing follows
Explanation
The word only makes graduation a necessary condition for applying, so a successful applicant must be a graduate. It does not follow that every graduate applied, which would be the converse. Only statements are read as if not a graduate, then cannot apply.

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.
