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: In the decades preceding World War I, this stretch of coast became famous for its wildfowling; locals were looking for food, but some more affluent visitors hunted to collect rare birds; Norfolk's first barred warbler was shot on the point in 1884. In 1901, the Blakeney and Cley Wild Bird Protection Society created a bird sanctuary and appointed as its "watcher", Bob Pinchen, the first of only six men, up to 2012, to hold that post.In 1910, the owner of the Point, Augustus Cholmondeley Gough-Calthorpe, 6th Baron Calthorpe, leased the land to University College London (UCL), who also purchased the Old Lifeboat House at the end of the spit. When the baron died later that year, his heirs put Blakeney Point up for sale, raising the possibility of development. In 1912, a public appeal initiated by Charles Rothschild and organised by UCL Professor Francis Wall Oliver and Dr Sidney Long enabled the purchase of Blakeney Point from the Calthorpe estate, and the land was then donated to the National Trust. UCL established a research centre at the Old Lifeboat House in 1913, where Oliver and his college pioneered the scientific study of Blakeney Point. The building is still used by students, and also acts as an information centre. Despite formal protection, the tern colony was not fenced off until the 1960s.The Point was designated as a Site of Special Scientific Interest (SSSI) in 1954, along with the adjacent Cley Marshes reserve, and subsumed into the newly created 7,700-hectare (19,000-acre) North Norfolk Coast SSSI in 1986. The larger area is now additionally protected through Natura 2000, Special Protection Area (SPA) and Ramsar listings, IUCN category IV (habitat/species management area) and is part of the Norfolk Coast Area of Outstanding Natural Beauty. The Point became a National Nature Reserve (NNR) in 1994, and the coast from Holkham NNR to Salthouse, together with Scolt Head Island, became a Biosphere Reserve in 1976.
Output:
What is the title of the person whose heirs put Blakeney Point up for sale?
