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: Ryker, a former mercenary, comes out of retirement to take part in the overthrow of an African dictator. He travels to London to meet former war comrade Jesse Jones, and his associates Freddy Bradshaw and Temple Smith. After helping fellow mercenaries test and ship weapons to South Africa, Ryker begins to have ethical concerns about his involvement. He eventually distances himself from the others, and rents a flat in London. He falls into hippie culture, and begins dating a girl named Chrissie.
Jesse tracks down Ryker. Explaining that the operation is not producing the profits he expected, he tries to convince Ryker to return. Ryker declines, but develops a plan with Jesse to thwart the operation and take the money for themselves. They succeed and escape with Bradshaw's car. A weapons dealer named Rawlings pursues them.
Jesse discovers that their "take" is somewhat less than the amount of cash they supposedly embezzled. Ryker reveals that his real plan was to sabotage the gun running operation, not to take all the money. Jesse assaults Ryker; Ryker, now a pacifist, refuses to defend himself. Ryker is eventually forced to break Jesse's ankle to end his assault. As Ryker bundles Jesse into a car to seek medical treatment, Rawlings shoots them down with rifle fire.
