केवल एक भरी हुई 3-लीटर की बोतल और 1 लीटर तथा 4 लीटर की क्षमता वाली दो खाली बोतलें दी गई हैं, जो सभी बिना अंशांकन (un-graduated) की हैं। तीनों बोतलों में से प्रत्येक में ठीक 1 लीटर पानी सुनिश्चित करने के लिए आवश्यक उड़ेलने (pourings) की न्यूनतम संख्या क्या है?

S, U, P, R, V, Q, and T are colleagues. Each has a different designation: Field Supervisor, Caretaker, Manager, Senior Assistant, Storekeeper, Accountant, and Cashier (not necessarily in this order). There are three ladies. U is senior to V and junior to P only. The Caretaker is the senior-most. S is the Manager and is junior to Q, who is the Senior Assistant. T is the Storekeeper, senior to V, and junior to S. R's female friend is the junior-most. No lady is either a Cashier or a Caretaker. U is a female and a Field Supervisor. The junior-most in the group is not a Cashier. What is the designation of R?

P always speaks the truth and Q always lies. Both are locked inside a room with no third person present. Which of the following statements can be heard by an eavesdropper listening to the room?
