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.

Question: 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 Mono–Inyo 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?


Question: Passage: From her Parkville jail cell, Vergie Winters watches the funeral procession of Senator John Shadwell and remembers her twenty-year past with him: The moment young lawyer John returns to Parkville from an extended honeymoon with his social climbing wife Laura, he visits Vergie, his former lover. After a passionate embrace, John explains to the youthful milliner that he had abandoned their romance because Vergie's father had told him that she was pregnant by laborer Hugo McQueen and would be forced to marry. Vergie then tells John that, to keep her from marrying John, Laura's father had paid her father $10,000 to tell him that devastating lie.
Still deeply in love, John and Vergie continue to see each other, but when John starts to campaign for Congress, Preston, a political boss, informs Vergie that, if John is to receive his vital support, she must forego their affair. Although Vergie agrees to Preston's terms, John refuses to end the relationship and spends a long evening with her before the election. 
After a victorious win, John moves to Washington, D.C. with Laura, Vergie bears his child under an assumed name. John then adopts the baby, named Joan, whom he claims is the child of a destitute family friend. 
At the start of World War I, John returns to Parkville and once again resumes his affair with Vergie. When one of John's late night rendezvous is witnessed by a town gossip and reported to Mike Davey, John's only political enemy, Vergie's successful millinery shop is boycotted, and she is shunned by all but the local prostitutes. In addition, Davey hires Preston's son Barry to steal from Preston's home safe a page from a hotel register on which Vergie had written her assumed name. As Barry is breaking into his father's safe, however, Preston mistakes him for a burglar and kills him, but tells his butler that a burglar shot his son.

Answer: What is the full name of the person who visits their former lover?


Question: Passage: Canadian ex-serviceman Bob Regan returns to Oldchester, the English town where he was stationed during the war, hoping to find Pat Lane, the girl he fell in love with.  He meets up with Mike Collins, an old acquaintance who now manages Oldchester United, the local football club.  He also renews his friendship with Collins' daughter Jackie.
Mike tells Bob of an odd proviso surrounding the allocation of £25,000 from the estate of a recently deceased businessman and supporter of the football club – if Oldchester United win promotion to the next division of the Football League that season the money is theirs, if not it goes to the man's nephew.  He remembers Bob as a skilful footballer, and asks him to sign up for the team to boost the promotion quest.  Bob agrees.
The nephew Nick Hammond is determined that the money will be his, and is worried that Bob's football prowess may well propel the team to on-pitch success.  He is acquainted with Pat, now living in London, and persuades her to join him in a scheme to scupper Oldchester's chances.  Knowing of Bob's fondness for Pat, and that Pat cares nothing for Bob, he proposes that if Pat can tempt Bob away from Oldchester and the football team, and the team fails in its promotion bid, he will give her a share of the inheritance.  The mercenary Pat jumps at the prospect, begins to work her charms on Bob and soon lures him to London to be with her.  He is talent-spotted by scouts, and signed up by Arsenal F.C.

Answer:
What's the full name of the person the daughter of the football club manager befriends?
