Q: 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.
Passage: Jim is a promising young English merchant seaman who rises to first officer under Captain Marlow. However, Jim is injured and left at Java. When he is fit again, he signs on with the first available ship, a dilapidated freighter called the S.S. Patna, crammed with hundreds of Muslims on pilgrimage to Mecca. When a storm threatens the leaking ship, the crew panics and takes to the lifeboats, abandoning their passengers; in a moment of weakness Jim joins them.
When they reach port, the sailors are stunned to find an intact Patna already there before them. The rest of the crew disappears, but Jim insists on confessing his guilt at an official inquiry and is stripped of his sailing papers. Filled with self-loathing, Jim becomes a drifter.
One day, he saves a boatload of gunpowder from sabotage. Stein, the cargo's owner, offers him an extremely dangerous job: transporting it and some rifles by river to distant Patusan to help Stein's old friend, the town's chief, lead an uprising against bandits led by the General.
When Schomberg is bribed to deny Stein the use of the motorboat he had promised, Jim takes a sailboat with two native crewmen, leaving the aged Stein behind. As they near their destination, one of the crewmen reveals himself to be working for the General. He kills the other sailor then flees to warn the warlord. Jim manages to hide the cargo before he is captured.
Though tortured, he refuses to divulge the location. This surprises Cornelius, the drunken, cowardly agent of Stein's trading company, who in fact obeys the General. That night, the Girl leads Jim's rescue.
A:
