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: As a result of the Berlin Conference of 1884-1885, the Congo Basin is claimed by King Leopold II of the Belgians, who rules the Congo Free State in personal union with the Kingdom of Belgium. The country is on the verge of bankruptcy, Leopold having borrowed huge sums of money to finance the construction of railways and other infrastructure projects. He sends his envoy Léon Rom to secure the fabled diamonds of Opar. Rom's expedition is ambushed and massacred. A tribal leader, Chief Mbonga, offers Rom the diamonds in exchange for an old enemy: Tarzan.
The man once called "Tarzan", John Clayton III, has left Africa behind and settled down in London with his American-born wife, Jane Porter. He took up his birth name and ancestral family residence as Lord Greystoke. In the eight years since returning from Africa, John's story as Tarzan has become legendary among the Victorian public, although John wants to leave that past behind. Through the British Prime Minister, John is invited by King Leopold to visit Boma and report on the development of the Congo by Belgium; he declines to participate in the perceived publicity stunt.
answer:
What is the first name of the person who sends his envoy to secure diamonds?


question:
Passage: In 1879, Smetana had written to a friend, the Czech poet Jan Neruda, revealing fears of the onset of madness. By the winter of 1882–83 he was experiencing depression, insomnia, and hallucinations, together with giddiness, cramp and a temporary loss of speech. In 1883 he began writing a new symphonic suite, Prague Carnival, but could get no further than an Introduction and a Polonaise. He started a new opera, Viola, based on the character in Shakespeare's Twelfth Night, but wrote only fragments as his mental state gradually deteriorated. In October 1883 his behaviour at a private reception in Prague disturbed his friends; by the middle of February 1884 he had ceased to be coherent, and was periodically violent. On 23 April his family, unable to nurse him any longer, removed him to the Kateřinky Lunatic Asylum in Prague, where he died on 12 May 1884.
The hospital registered the cause of death as senile dementia. However, Smetana's family believed that his physical and mental decline was due to syphilis. An analysis of the autopsy report, published by the German neurologist Dr Ernst Levin in 1972, came to the same conclusion. Tests carried out by Prof. Emanuel Vlček in the late 20th century on samples of muscular tissue from Smetana's exhumed body provided further evidence of the disease. However, this research has been challenged by Czech physician Dr Jiří Ramba, who has argued that Vlček's tests do not provide a basis for a reliable conclusion, citing the age and state of the tissues and highlighting reported symptoms of Smetana's that were incompatible with syphilis.Smetana's funeral took place on 15 May, at the Týn Church in Prague's Old Town. The subsequent procession to the Vyšehrad Cemetery was led by members of the Hlahol, bearing torches, and was followed by a large crowd. The grave later became a place of pilgrimage for musical visitors to Prague. On the funeral evening, a scheduled performance of The Bartered Bride at the National Theatre was allowed to proceed, the stage draped with black cloth as a mark of respect.Smetana was survived by Bettina, their daughters Zdeňka and Božena, and by Žofie. None of them played any significant role in Smetana's musical life. Bettina lived until 1908; Žofie, who had married Josef Schwarz in 1874, predeceased her stepmother, dying in 1902. The younger daughters eventually married, living out their lives away from the public eye. A permanent memorial to Smetana's life and work is the Bedřich Smetana Museum in Prague, founded in 1926 within the Charles University's Institute for Musicology. In 1936 the museum moved to the former Waterworks building on the banks of the Vltava, and since 1976 has been part of the Czech Museum of Music.The asteroid 2047 Smetana was named in his honour.

What is the full name of the person who was experiencing depression, insomnia, and hallucinations, together with giddiness, cramp and a temporary loss of speech by the winter of 1882-83?


question:
Passage: The equestrian statue of Edward Horner stands inside St Andrew's Church in the village of Mells in Somerset, south-western England. It was designed by the architect Sir Edwin Lutyens, as a memorial to Edward Horner, who died of wounds in the First World War. The sculpture was executed by Alfred Munnings.
Edward Horner was the only surviving son and heir of Sir John and Lady Frances Horner of Mells Manor and a member of an extended upper-class social group known as the Coterie, many of whom were killed in the war; the group included his fiancée and his future brother-in-law. Shortly after the war broke out, he was a yeomanry officer in the part-time Territorial Force but he was keen to join the fighting on the Western Front and obtained a transfer to a cavalry regiment through his family's connections. He was wounded in May 1915 and did not return to the war until early 1917. He was assigned a staff post but again secured a transfer to the front line. Shortly after his return to the fighting, on 21 November 1917, he was wounded again; he died the same day.
Lutyens was a friend of the Horner family, having designed multiple buildings and structures for them since the beginning of the 20th century. As well as Horner's memorial, he designed a memorial to Raymond Asquith (also in St Andrew's Church), and Mells War Memorial in the centre of the village. For Horner's memorial, Lutyens designed the plinth himself, and engaged the renowned equestrian painter and war artist Alfred Munnings for the latter's first public work of sculpture. The plinth is in Portland stone and set into it is Horner's original grave marker; the family's coat of arms is carved into the front, while the sides bear various dedicatory inscriptions. The statue is a bronze of a cavalry officer on horseback, bare-headed, with his helmet and sword on the horse's saddle. Lutyens was known for abstract and ecumenical themes in his war memorial designs, but the statue of Horner is an example of his use of more conventional imagery to commemorate an individual. Installed in the Horner family chapel in St Andrew's Church in 1920 at a cost of £1,000, it was moved to its present location in the church in 2007.
answer:
What is the first name of the person who was a friend of the Horner family?
