Statements: I. Some roses are flowers.II. Some flowers are buds. III. All buds are leaves. IV. All leaves are plants.Conclusions: I. Some plants are flowers. II. Some roses are buds. III. All leaves are roses. IV. No roses are buds.
Correct answer: D. Only I and either II or IV follow
- A. Only I follows
- B. Only I and II follow
- C. I and either II or IV follow
- D. Only I and either II or IV follow
Explanation
• All leaves are plants → any subset of leaves (buds, flowers) are part of plants → Conclusion I is true. • Some flowers are buds, but we cannot definitively link roses to buds → either II or IV may be true, not both. • Conclusion III is false (all leaves are not roses).

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
