RRB Technician Grade I 19 Dec 2024 Shift 2 Paper

Concept:Use a Venn diagram to check only definite conclusions that must follow in every case.Explanation:All parks are grounds → the parks circle lies completely inside the grounds circle.Some grounds are museums → only a part of the grounds circle overlaps with the museums circle.No museum is a theatre → the museums circle and the theatres circle do not touch each other.Conclusion I: "All museums are parks" is not definite because museums are connected only to some grounds, not directly to all parks.Conclusion II: "No ground is a theatre" is not definite because only the grounds that are museums are definitely not theatres. Other grounds may or may not be theatres.Therefore, neither conclusion definitely follows from the given statements.Answer:Neither conclusion I nor II follows.Hence, the correct answer is Option B.
