In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Input: Consider Input: Passage: There is considerable uncertainty about the identities of the Grand Dukes of Lithuania between Traidenis' death in 1282 and Vytenis' assumption of power in 1295. This is in part because the two main sources for Lithuanian history in the 13th century, the Hypatian Codex and the Livonian Rhymed Chronicle, end in the early 1290s. In 1285, one chronicle mentions Daumantas as Grand Duke. He attacked the Bishop of Tver and was severely wounded or even killed in the battle. However, that is the only information about him.
The Gediminid dynasty began its ascent in Lithuania during this time with the emergence of its first leader, Butigeidis. In 1289, leading about 8,000 troops, he attacked Sambia. In 1289 the Teutonic Knights built a castle in present-day Sovetsk (Tilsit) and their raids intensified. Butigeidis was the first to build strong castles along the Neman River. He died in 1290 or 1292, and his brother Butvydas (also known as Pukuveras) inherited the crown. Butvydas was the father of Vytenis and probably of Gediminas. During his short reign Butvydas tried to defend the duchy against the Teutonic Knights; he also attacked Masovia, an ally of the knights. His son, Vytenis, advanced to power in 1295 and ended the period of relative instability. His reign marks the transition from the state's establishment to the point at which it was poised for expansion. 
Question: What is the alias of the person that inherited the crown from Butigeidis?

Output: Pukuveras.


Input: Consider Input: Passage: At first, Baylis presented both drama and opera at each of her theatres.  The companies were known as the "Vic-Wells".  However, for both aesthetic and financial reasons, by 1934, the Old Vic had become the home of the spoken drama, while Sadler's Wells housed both the opera and a ballet company, the latter co-founded by Baylis and Ninette de Valois in 1930.Lawrance Collingwood joined the company as resident conductor alongside Corri.  With the increased number of productions, guest conductors were recruited, including Geoffrey Toye and Anthony Collins. The increasing success of the new ballet company helped to subsidise the high cost of opera productions, enabling a further increase in the size of the orchestra, to 48 players. Among the singers in the opera company were Joan Cross and Edith Coates. In the 1930s, the company presented standard repertoire operas by Mozart, Verdi, Wagner and Puccini, lighter works by Balfe, Donizetti, Offenbach and Johann Strauss, some novelties, among which were operas by Holst, Ethel Smyth and Charles Villiers Stanford, and an unusual attempt at staging an oratorio, Mendelssohn's Elijah.In November 1937, Baylis died of a heart attack. Her three companies continued under the direction of her appointed successors: Tyrone Guthrie at the Old Vic, in overall charge of both theatres, with de Valois running the ballet, and Carey and two colleagues running the opera. In the Second World War, the government requisitioned Sadler's Wells as a refuge for those made homeless by air-raids. Guthrie decided to keep the opera going as a small touring ensemble of 20 performers. Between 1942 and the war's end in 1945, the company toured continuously, visiting 87 venues. Joan Cross led and managed the company, and also sang leading soprano roles in its productions when needed. The size of the company was increased to 50, and then to 80. By 1945, its members included singers from a new generation such as Peter Pears and Owen Brannigan, and the conductor Reginald Goodall. 
Question: What is the first name of the person who decided to keep the opera going as a small touring ensemble of 20 performer?

Output: Tyrone.


Input: Consider Input: Passage: Three sisters, Veronica, Victoria and Elizabeth, receive letters from their late father's lawyer informing them of their father's wish that they spend three nights in his house on an isolated island before his will can be read. They and their husbands William, Richard and Donald are met there by the two maids, Martha and Ruth, and a hunchback named Colin whom the audience has already seen murdering two people at the beginning of the film. While helping with the luggage Colin becomes angry and catches and eats a live rabbit. The remains of the rabbit are later found in Veronica and William's bed, along with a note reading "Blessed are the meek for they shall inherit".
Victoria and Robert find that someone has painted a large 'X' in blood on their bedroom door. Robert and Donald go downstairs to investigate, but Donald collapses after being drugged. Robert investigates the cellar and sees someone he recognizes. Shortly afterward, Victoria finds his body hanging by the ankles on the stairs. The next morning, while discussing what happened, Ruth asks Martha if she had tied up Colin that night.
Colin attempts to tell Victoria something but is interrupted by Martha and sent to chop firewood in the cellar with Donald (who is given a leather strap to use on Colin). Donald finds a plank of wood with a bloody 'X' on it, but is attacked from behind, gagged and bound to a workbench before being disemboweled and cut in two by a hooded figure.
At dinner, the guests ask about Donald and Elizabeth's whereabouts. When dinner is served, Elizabeth's severed head is in the serving dish.
William goes into the cellar to investigate and finds a box and a photograph. Colin steals the photo from him, however, and William is then attacked and killed with a pitchfork by the hooded figure. Later, Martha finds Colin with the photo and realizes what it means, but is killed with a hatchet. Colin tries to escape from the killer, but is set alight. 
Question: Who is found hanging on the stairs?


Output: Robert.
