Instructions: 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: Passage: The White House is connected to The Barn (originally The Stables), a red-brick building built in 1926. The archway in the centre of the building was originally an open passageway. It now houses the reception area for the Training and Event Centre. The first floor of the building was used as training rooms for Cub Scout Leaders. The clock on the front of the building was a gift from a former Japanese Chief Scout, Count Sano, who was present at an early training course at Gilwell Park. The weather vane on the roof depicts Dick Turpin, who was rumoured to live on the site.
Close to the estate entrance, The Lodge was built in 1934 as the Camp Chief's (later succeeded by the Director of Programme and Development) home. The building is now used to accommodate Scout Association staff and host internal meetings.
The Gilwell Farm is the oldest building on the site still standing, dating from the 1600s. The building started as two separate cottages. In the grounds of the building is the last remaining well on site, known as Gil Well. The Farm was refurbished from its derelict site, opening in 2015 as the new offices and reception of Scout Adventures Gilwell Park . Close by, The Leopard Gates mark the original entrance to Gilwell Park, and were carved by Gilwlel master craftsman Don Potter in 1928.
The Lid, which originally consisted of a roof but no walls, was a wet weather shelter built in 1967. In 2009, the building was renovated and now consists of a large activity hall, two classrooms, staff space and a large store room added The activity hall houses all the indoor activities on-site, including an archery range and climbing walls. In front of The Lid, is the Tait McKenzie Statue, gifted by the Boy Scouts of America in 1966.
The Barnacle was built in 1950 as a First Aid centre, which quickly became a volunteer-run cottage hospital for visitors and the local community. It houses a 6-bed ward, isolation room, dental surgery, X-ray room and operating theatre. In the late 1980s the building became volunteer accommodation, until it was decommissioned in 2016 with the opening of the International Volunteer Lodge. The building now stands empty, awaiting an uncertain future.
The Pigsty, a small gardeners shed located on The Orchard, has been preserved as the first campsite at Gilwell Park. The first group of Rover Scouts who arrived to prepare the site when it was purchased in 1919 slept here when the weather proved too bad to pitch their tents.
