Teacher:In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Teacher: Now, understand the problem? Solve this instance: Passage: The story begins with the Japanese army's defeat of the China forces occupying Hong Kong on 25 December 1941. Nicholas is an eleven-year-old boy whose  parents have both suddenly disappeared in the chaos of war breaking out.  As the Japanese come to do a home to home search, three loyal family servants, Tang, his wife Ah Mee, and the gardener Ah Kwan take Nicholas and they escape to Kowloon as Hong Kong Island is no longer safe. Upon reaching the shore of Kowloon, Tang and Ah Mee disguise Nicholas as a Chinese boy and the trip continues to Tang's home village, the village of Sek Wan.
Nicholas passes the years of the war here with Tang and his family. He is given the Chinese name Wing Ming. During this time, many events happen. Nicholas makes a dangerous journey back to Kowloon to get quinine cure to the malaria Tang has contracted. He also helps the Communist partisan army – The East River Column Fighters-  to translate instructions for using heavy explosives. Nicholas joins the partisan army on a mission to Kowloon where they blow up a railway bridge and weaken the position of the Japanese army. Yet his most dangerous job would have been to deliver a medicine into the prison of war camps (POW camps). Taking news or items to prison camps is nicknamed "playing music on the bamboo radio". Nicholas does more than expected by entering the camp itself because the person who he was supposed to pass the medicine to had the fever. Exhausted and worried, Nicholas narrowly escapes the clutches of the Japanese with the help of the prisoners and finally reaches the safety of Sek Wan village.
Student:
