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: 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.
answer:
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?

Passage: "Ooh La La", Supernature's opening track, inspired by T. Rex, was chosen as its lead single "because it was up and in your face and it carried on the theme of the glammy, discoey beat from the last album". It was the duo's first song to feature the electric guitar, and received positive reviews, often being noted as a highlight of the album. "Ooh La La" became Goldfrapp's most successful single on the UK Singles Chart to date when it peaked at number four, while topping the Billboard Hot Dance Club Play chart in the United States. The second track, "Lovely 2 C U", received mixed reviews from critics, with one reviewer stating that it was the "worst offender of sounding by-numbers, its lazy glam affectations sounding all the worse amid a chorus striking only in its complete dullness"."Ride a White Horse", the third single, was inspired by the disco era. Like previous singles from the album, the song was another top-20 single in the UK, where it peaked at number 15. The ballads "You Never Know" and "Let It Take You" have minimal background electronics, and were generally well received by critics, who drew comparisons to Goldfrapp's debut album Felt Mountain. Goldfrapp's performance on "You Never Know" was described as "chameleonic" with odes to Debbie Harry and Siouxsie Sioux. "Fly Me Away", another synth ballad, had an associated music video which featured Goldfrapp as an animated doll; the video, however, was never released. Serving as the fourth and final single from Supernature, the song was not heavily promoted and was less commercially successful than the other singles, peaking at number 26 on the UK chart. "Slide In", an electroclash song about sex, and "Koko" were compared to Gary Numan's early compositions."Satin Chic" is a disco song with glam rock and cabaret influences, similar to early Elton John. Cited by Goldfrapp and Gregory as their favourite song on Supernature, it was remixed by The Flaming Lips, and issued as a limited-edition single on 4 September 2006. The 10th track, "Time Out from the World", features an orchestra and whispered vocals by Goldfrapp. Critics liked the song, writing that it was an "exception to the prevailing style of Supernature" due to its "haunting, yet glamorous, atmospherics". The album's closing track and second single "Number 1" is about the importance and meanings of relationships. The song, which is based around a synth and bass arrangement, reached number nine on the UK Singles Chart and number one on the US Hot Dance Club Play chart.
answer:
What are the last names of the people in the duo whose first song to feature electric guitar was "Ooh La La?"?

Passage: Scrat is once again trying to bury his acorn but accidentally activates an abandoned alien ship that takes him into deep space, where he unwittingly sends several asteroids en route to a collision with Earth. Meanwhile, Manny and Ellie are preparing upcoming marriage between Peaches and her fiance, Julian. Diego and his wife Shira want to start a family, but their fierce appearance tends to scare kids. Sid is dumped by his girlfriend, Francine, just as he is about to propose to her, and he laments his solitude. During Manny and Ellie's wedding anniversary party, some of the asteroids strike the place and The Herd barely escape. Meanwhile, at the underground lost world, Buck returns a dinosaur egg back to its rightful owner after it was stolen by a trio of flying dromaeosaurs named Gavin, Gertie, and Roger. Buck discovers an ancient stone pillar and takes it to the surface, where he meets Manny and the others.
Buck explains to The Herd that according to the pillar, the asteroids had caused several extinctions in the past and with a massive one still incoming, he believes that the only place they could find a clue to stop it is on the site of the impact of the previous ones, as according to its engravings, they always fall at the same place. However, the three dromaeosaurs overhear their conversation, and Gavin and Gertie decide to stop them, believing that they could easily avoid the impact, thus not only getting their revenge on Buck, but also killing all mammals and securing domination over Earth for their species. Roger is reluctant, but Gavin and Gertie strong-arm him into cooperating.
answer:
Who is the person that meets Buck on the surface married to?
