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. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
question:
Passage: Mauna Kea is one of five volcanoes  that form the island of Hawaii, the largest and youngest island of the Hawaiian–Emperor seamount chain. Of these five hotspot volcanoes, Mauna Kea is the fourth oldest and fourth most active. It began as a preshield volcano driven by the Hawaii hotspot around one million years ago, and became exceptionally active during its shield stage until 500,000 years ago. Mauna Kea entered its quieter post-shield stage 250,000 to 200,000 years ago, and is currently dormant. Mauna Kea does not have a visible summit caldera, but contains a number of small cinder and pumice cones near its summit. A former summit caldera may have been filled and buried by later summit eruption deposits.
Mauna Kea is over 32,000 km3 (7,680 cu mi) in volume, so massive that it and its neighbor, Mauna Loa, depress the ocean crust beneath it by 6 km (4 mi).
Mauna Kea is the only Hawaiian volcano with distinct evidence of glaciation. Similar deposits probably existed on Mauna Loa, but have been covered by later lava flows. Despite Hawaii's tropical location, during several past ice ages a drop of a degree in temperature allowed snow to remain at the volcano's summit through summer, triggering the formation of an ice cap. There are three episodes of glaciation that have been recorded from the last 180,000 years: the Pōhakuloa (180–130 ka), Wāihu (80–60 ka) and Mākanaka (40–13 ka) series. These have extensively sculpted the summit, depositing moraines and a circular ring of till and gravel along the volcano's upper flanks. Subglacial eruptions built cinder cones during the Mākanaka glaciation, most of which were heavily gouged by glacial action. The most recent cones were built between 9000 and 4500 years ago, atop the glacial deposits, although one study indicates that the last eruption may have been around 3600 years ago.At their maximum extent, the glaciers extended from the summit down to between 3,200 and 3,800 m (10,500 and 12,500 ft) of elevation. A small body of permafrost, less than 25 m (80 ft) across, was found at the summit of Mauna Kea before 1974, and may still be present. Small gullies etch the summit, formed by rain- and snow-fed streams that flow only during winter melt and rain showers.
answer:
What was likely covered by later lava flows on Mauna Loa?


question:
Passage: Harrison married model Pattie Boyd on 21 January 1966, with McCartney serving as best man. Harrison and Boyd had met in 1964 during the production of the film A Hard Day's Night, in which the 19-year-old Boyd had been cast as a schoolgirl. They separated in 1974 and their divorce was finalised in 1977. Boyd said her decision to end the marriage was due largely to George's repeated infidelities. The last infidelity culminated in an affair with Ringo's wife Maureen, which Boyd called "the final straw". She characterised the last year of their marriage as "fuelled by alcohol and cocaine", and she stated: "George used coke excessively, and I think it changed him ... it froze his emotions and hardened his heart." She subsequently moved in with Eric Clapton, and they married in 1979.Harrison married Dark Horse Records' secretary Olivia Trinidad Arias on 2 September 1978. They had met at the A&M Records offices in Los Angeles in 1974, and together had one son, Dhani Harrison, born on 1 August 1978.He restored the English manor house and grounds of Friar Park, his home in Henley-on-Thames, where several of his music videos were filmed including "Crackerbox Palace"; the grounds also served as the background for the cover of All Things Must Pass. He employed ten workers to maintain the 36-acre (15 ha) garden. Harrison commented on gardening as a form of escapism: "Sometimes I feel like I'm actually on the wrong planet, and it's great when I'm in my garden, but the minute I go out the gate I think: 'What the hell am I doing here?'" His autobiography, I, Me, Mine, is dedicated "to gardeners everywhere". The former Beatles publicist Derek Taylor helped Harrison write the book, which said little about the Beatles, focusing instead on Harrison's hobbies, music and lyrics. Taylor commented: "George is not disowning the Beatles ... but it was a long time ago and actually a short part of his life."Harrison had an interest in sports cars and motor racing; he was one of the 100 people who purchased the McLaren F1 road car. He had collected photos of racing drivers and their cars since he was young; at 12 he had attended his first race, the 1955 British Grand Prix at Aintree. He wrote "Faster" as a tribute to the Formula One racing drivers Jackie Stewart and Ronnie Peterson. Proceeds from its release went to the Gunnar Nilsson cancer charity, set up after the Swedish driver's death from the disease in 1978. Harrison's first extravagant car, a 1964 Aston Martin DB5, was sold at auction on 7 December 2011 in London. An anonymous Beatles collector paid £350,000 for the vehicle that Harrison had bought new in January 1965.
answer:
What were the last names of the two people who were married and McCartney was the best man?


question:
Passage: Nurse Laura Mattson and World War I military pilot Lt. Geoffrey Aiken fall in love after only knowing each other for a few days. Tragically, he is brought to her hospital and, by chance, put under her care after being fatally wounded on his very first mission. After he dies, Laura realizes she is pregnant. Edward Seward loves her and persuades her to marry him. As far as anyone knows, the child will be his.
By 1940, Laura's son Bob has grown into a young man, newly engaged to Peggy Chase. Laura has raised Bob to embrace pacifism. Meanwhile, Edward Seward, now United States Secretary of State, flies home after having negotiated the Seward Peace Treaty, which he claims will make it impossible for any country to go to war again. However, when the U.S. ambassador to the state of "Eurasia" is assassinated while en route to the Eurasian State Department to discuss an earlier diplomatic incident, the President sends the navy across the Atlantic to underscore the U.S. demand for a formal apology. Eurasia refuses to comply, and another world war becomes inevitable despite the treaty.
Laura speaks at a large peace rally, over her husband's strong objection. The rally is broken up a group of angry men. A mob then gathers at the Seward home and starts pelting the place. Edward manages to disperse the crowd by first reminding the mob of each American's right to voice his or her own opinion in peacetime, and pledging himself wholeheartedly to the struggle once war is declared. When a news reporter interviews him, he insists his son will enlist. Bob categorically denies this, causing Peggy to break off their engagement. Unable to get his son to change his mind, Edward tells him that he at least has no right to sully the Seward name, revealing that he is not Bob's father. Laura confirms it, and tells Bob of his real father and how he died.
answer:

Who is Bob's father?
