instruction:
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.

Passage: The chain of craters has been the subject of several writers and naturalists. Mark Twain visited Mono Basin in the 1860s and wrote about Mono Lake, but did not mention any of the MonoInyo Craters except for the lake's two volcanic islands. He wrote in Roughing It (1872) that the lake was in a "lifeless, hideous desert ..." that was the "loneliest spot on earth ... little graced with the picturesque."
Naturalist John Muir explored the area in 1869. He described the "Mono Desert" as a "... country of wonderful contrasts. Hot deserts bounded by snow-laden mountains,cinders and ashes scattered on glacier-polished pavements,frost and fire working together in the making of beauty. In the lake are several volcanic islands, which show that the waters were once mingled with fire." Muir described the Mono Craters as "... heaps of loose ashes that have never been blest by either rain or snow ..."In the spring of 1881 and the fall of 1882, geologist Israel Russell studied the area as a side-trip during his field research of Lake Lahontan, a now dry lake that covered much of nearby Nevada during the last glacial period. His Quaternary History of the Mono Valley (1889), which included a topographic survey by Willard D. Johnson, was the first thorough scientific description of Mono Lake and its volcanic features.
Russell named the Mono Craters and wrote: "The attention of every one who enters Mono Valley is at once attracted by the soft, pleasing colors of these craters as well as by the symmetry and beauty of their forms. They are exceptional features in the scenery of the region, and are rendered all the more striking by their proximity to the angular peaks and rugged outlines of the High Sierra.".
answer:
What is the name of the place that has two volcanic islands?

Passage: British couple Nigel and Fiona Dobson are on a Mediterranean cruise ship to Istanbul en route to India. They encounter a beautiful French woman, Mimi, and that night Nigel meets her while dancing alone in the ship's bar. Later Nigel meets her much older and disabled American husband Oscar, who is acerbic and cynical, having been jaded and a failure as a writer.
Oscar invites Nigel to his cabin where he tells Nigel in great detail how he and Mimi first met on a bus in Paris and fell passionately in love. Nigel relates all to Fiona. Both are appalled by Oscar's exhibitionism, but Nigel is also fascinated by Mimi, who provokes him. Later, Oscar narrates how they explored bondage, sadomasochism, and voyeurism. As a contrast to their sexual adventurousness, we see Nigel and Fiona meeting a distinguished Indian gentleman, Mr. Singh, who is traveling with his little daughter Amrita.
Invited by Mimi, Nigel, escaping from a bridge game, goes to meet her in her cabin, but it turns out she and Oscar have played a joke on him. Nigel wants to leave, but another session unfolds, with Oscar describing how their hate/love relationship developed. Bored, he tried to break up, but Mimi begged him to let her live with him under any conditions. He complied, but started to explore sadistic fantasies at her expense, humiliating her in public. When Mimi became pregnant, he made her have an abortion, saying that he would be a terrible father. When he visited her in hospital, he was shocked by her condition and almost relented in his attempts to drive her away. He promised her a holiday in the Caribbean, but he got off the plane just before take off. Mimi departed alone, crying.
answer:
Which person got Mimi pregnant?

Passage: During the rage of Hurricane Katrina, Detective Andy Devereaux discovers the body of his former partner in a close to underwater warehouse. Quickly forgetting about his discovery, he joins a newly transferred detective named Stan Johnson (Curtis "50 Cent" Jackson) trying to end a conflict involving looters.
Post-Katrina, Andy and Stan are now partners. They work with corrupt detectives Pepe and Barney, who are caught up in the murder of an undercover narcotics agent. Investigating the escalating police corruption in New Orleans is FBI Agent Brown. Brown brings up his thoughts to Police Captain Friendly who insists he is doing his best to solve the problems in his department.
Meanwhile, police therapist Nina Ferraro tries to help the detectives with their struggles, with little avail. She is particularly interested in Andy, whose father, also a detective, was murdered in the line of duty.
Things are complicated further with Agent Brown's investigation into Andy and his crew. Brown tells Andy that he has an informant who is leaking out the details, and Andy, disbelieving at first, begins to resign himself to the fact that one of his men is betraying him.
After Captain Friendly is assassinated by a local gangster named Chamorro, Andy, Stan, Pepe, and Barney decide to take the law into their own hands and go after Chamorro. While interrogating Chamorro, they find out that Brown has been supplying the drug dealer with information about the police raids, to help his own investigation. In a violent shootout, Barney accidentally shoots and kills Pepe.
Andy and Stan escape, only to return to the warehouse where they met. There Andy realizes that Stan is the informant. After the two start arguing, Brown shows up and there is another shootout, ending in Brown's death. Andy comforts a sobbing Stan, then Andy kills his partner, as he possibly did with his previous one.
answer:
What's the full name of the person now partnered with the detective who found his previous partner's body?
