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.

Input: Consider Input: Passage: The estate's condition declined more during the 1910s. William de Bois Maclaren was a publisher and Scout Commissioner from Rosneath, Dumbartonshire, Scotland. During a business trip to London, Maclaren was saddened to see that Scouts in the East End had no suitable outdoor area to conduct their activities. He contacted Lord Robert Baden-Powell, who appointed P.B. Nevill to handle the matter. Nevill was Scout Commissioner of the East End.
On 20 November 1918 over dinner at Roland House, the Scout Hostel in Stepney, Maclaren agreed to donate £7,000 to the project. Part of the agreement included narrowing the areas to look for suitable land to Hainault Forest and Epping Forest. Rover Scouts searched both without success, but then John Gayfer, a young assistant Scoutmaster, suggested Gilwell Hall, a place he went bird-watching. Nevill visited the estate and was impressed, though the buildings were in poor condition. The estate was for sale for £7,000, the price Maclaren had donated. The estate totaled 21 hectares (52 acres) at the time.
The estate was purchased in early 1919 by Maclaren for the Boy Scout Association. Nevill first took his Rover Scouts to begin repairing the estate on Maundy Thursday, 17 April 1919. On this visit, the Rovers slept in the gardener's shed in the orchard because the ground was so wet they could not pitch tents. They called this shed "The Pigsty" and though dilapidated, it still stands, as it is the site of the first Scout campsite at Gilwell Park. Maclaren was a frequent visitor to Gilwell Park and helped repair the buildings. His dedication was so great that he donated another £3,000. Maclaren's interest had been in providing a campground, but Baden-Powell envisioned a training centre for Scouters.
An official opening was planned for 19 July 1919 but it was delayed until Saturday, 26 July 1919 so that Scouts could participate in the Official Peace Festival commemorating the end of World War I. Invitations were changed by hand to save money. Significant remodeling and construction was done in the 1920s. Because of limited finances, few improvements were made during the Great Depression of the 1930s.
Baden-Powell never lived at Gilwell Park but he often camped, lectured, taught courses, and attended meetings. He emphasized the importance of Scouters' training at Gilwell Park for Scouting by taking it as the territorial designation in his peerage title of 1st Baron Baden-Powell of Gilwell in 1929 when the barony was conferred upon him by the king.

Output: What is the last name of the person who contacted Lord Robert Baden-Powell, who appointed P.B. Nevill to handle the matter involving a lack of suitable outdoor areas?


Input: Consider Input: Passage: In 1946, after fighting in World War II, two former United States Air Force pilots in North Africa, Brynie MacKay and Mike Brewer are forced to work for Lee Harris, an international smuggler to get money needed for their return to civilian life.  The smuggler wants them to fly to France, with Egyptian cotton cargo. When Brynie finds that their real cargo is contraband cigarettes, he extorts Harris for more money. In retaliation, Harris plants narcotics on Brynie's aircraft and informs Colonel Wilson at U. S. Counterintelligence.
With Byrnie's aircraft impounded and his money seized, Elena, Harris's mistress comes to his aid. Harris exacts a promise for 12 more illegal cargo flights, but Mike warns that they will both be killed if they go ahead with this scheme. When Mike tries to trap Harris by informing Col. Wilson about the smuggling runs, Harris, who is flying with the two pilots, kills Mike, but is knocked out by Byrnie.
Fearing Harris's gang is waiting for him at the prearranged destination, Byrnie lands his aircraft at an abandoned military air strip and informs Wilson where the contraband can be found.  With Elena at his side, Byrnie then escapes to North Africa. When Harris tracks them down, Brynie overcomes Harris and turns him over to Wilson, and because of the deal Mike had made, is released. Byrnie decides to return to the United States with Elena and become a teacher, his former profession.

Output: What is the first name of the man that extorts the smuggler after discovering what the cargo is?


Input: Consider Input: Passage: Stereolab's music combines a droning rock sound with lounge instrumentals, overlaid with sing-song female vocals and pop melodies, and have also made use of unorthodox time signatures. It has been generally described as avant-pop, indie pop, art pop, indie electronic, indie rock, post-rock, experimental rock, and experimental pop.The band have played on vintage electronic keyboards and synthesizers from brands such as Farfisa and Vox and Moog. Gane has praised the instruments for their versatility: "We use the older effects because they're more direct, more extreme, and they're more like plasticine: you can shape them into loads of things." The 1994 album Mars Audiac Quintet prominently features Moog synthesizers.
Lætitia Sadier's English and French vocals was a part of Stereolab's music since the beginning; and would occasionally sing wordlessly along with the music.  In reference to her laid-back delivery, Peter Shapiro wrote facetiously in Wire that Sadier "display[ed] all the emotional histrionics of Nico", while some critics have commented that her vocals were unintelligible. Sadier would often trade vocals with Mary Hansen back-and-forth in a sing-song manner that has been described as "eerie" and "hypnotic", as well as "sweet [and] slightly alien". After Hansen's death in 2002, critic Jim Harrington commented that her absence is noticeable on live performances of Stereolab's older tracks, and that their newer songs could have benefited from Hansen's backing vocals.In interviews, Gane and Sadier have discussed their musical philosophy. Gane said that "to be unique was more important than to be good." On the subject of being too obscure, he said in a 1996 interview that "maybe the area where we're on dodgy ground, is this idea that you need great knowledge [of] esoteric music to understand what we're doing." Sadier responded to Gane, saying that she "think[s] we have achieved a music that will make sense to a lot of people whether they know about Steve Reich or not." The duo were up-front about their desire to grow their sound: for Gane, "otherwise it just sounds like what other people are doing", and for Sadier, "you trust that there is more and that it can be done more interesting.".


Output: What is the first name of the person who would often trade vocals with Mary Hansen back-and-forth in a sing-song manner?
