Problem: The answer to the question: What is the title of the grand commemorative piece. Tchaikovsky agreed to compose and finished it within six weeks? is inside the article: Tchaikovsky remained abroad for a year after the disintegration of his marriage. During this time, he completed Eugene Onegin, orchestrated his Fourth Symphony, and composed the Violin Concerto. He returned briefly to the Moscow Conservatory in the autumn of 1879. For the next few years, assured of a regular income from von Meck, he traveled incessantly throughout Europe and rural Russia, mainly alone, and avoided social contact whenever possible. During this time, Tchaikovsky's foreign reputation grew and a positive reassessment of his music also took place in Russia, thanks in part to Russian novelist Fyodor Dostoyevsky's call for "universal unity" with the West at the unveiling of the Pushkin Monument in Moscow in 1880. Before Dostoyevsky's speech, Tchaikovsky's music had been considered "overly dependent on the West". As Dostoyevsky's message spread throughout Russia, this stigma toward Tchaikovsky's music evaporated. An unprecedented acclaim for him even drew a cult following among the young intelligentsia of Saint Petersburg, including Alexandre Benois, Léon Bakst and Sergei Diaghilev.Two musical works from this period stand out. With the Cathedral of Christ the Saviour nearing completion in Moscow in 1880, the 25th anniversary of the coronation of Alexander II in 1881, and the 1882 Moscow Arts and Industry Exhibition in the planning stage, Nikolai Rubinstein suggested that Tchaikovsky compose a grand commemorative piece. Tchaikovsky agreed and finished it within six weeks. He wrote to Nadezhda von Meck that this piece, the 1812 Overture, would be "very loud and noisy, but I wrote it with no warm feeling of love, and therefore there will probably be no artistic merits in it". He also warned conductor Eduard Nápravník that "I shan't be at all surprised and offended if you find that it is in a style unsuitable for symphony concerts". Nevertheless, the overture became, for many, "the piece by Tchaikovsky they know best"., particularly well-known for the use of cannon in the scores.On 23 March 1881, Nikolai..., can you guess it ?

Problem: Given the question: The answer to the question: What is the name of the building in which included are rooms for the signing of official documents, negotiations, and tête-à-tête talks? is inside the article: During the time of the restoration, conducted by UkrNIIProektRestavratsiya and headed by Natalia Kosenko, the workers unearthed the whole lower floor, which had been filled in during Soviet times to strengthen the building's foundation. Restoration of the elaborate decor of the interior had to be fully redone. In the courtyard, the restorers placed an artificial lake, fountains, and a miniature garden—all of which had been in Horodecki's original plans.The building was opened as a filial "Masterpieces of Ukrainian Art" of the National Museum of Arts in November 2004. It was expected that the building would serve a dual purpose as a museum and as the presidential meeting place for state visitors. In April 2005, the Kiev City Council submitted a bill for 104 million hryvnias (approx. US $20 million) to the Ukrainian Government for reconstruction and restoration of the House with Chimaeras. The Council also allowed the Ukrainian government to construct a new square (closing off all automobile traffic) in front of the building for use in official ceremonies.Since May 2005, the building has been an official presidential residence, used for official and diplomatic ceremonies. The House with Chimaeras was used as a meeting place between Ukrainian President Viktor Yushchenko and Russian President Vladimir Putin, when the latter visited Kiev on December 22, 2006. Included in the building are rooms for negotiations, tête-à-tête talks, the signing of official documents, as well as a special room for the press., can you guess it ?

[Q]: The answer to the question: What is the first name of the person that wants to drink Selene's blood? is inside the article: The remaining vampire covens are on the verge of annihilation by the Lycans. Both species are searching for Selene: the vampires seek justice for the death of Viktor, while the Lycans, led by Marius, intend to use her to locate Eve, whose blood holds the key to building an army of vampire-werewolf hybrids. Semira, a council member of the Eastern Coven, tells Thomas she wants Selene to be granted clemency and to train the coven's neophyte Death Dealers. She asks Thomas to plead Selene's case before the full council; the plea is successful and the council reluctantly agrees to a pardon in exchange for Selene's help. Selene arrives with David. Semira has Varga, her ally and lover, poison Selene and slaughter the trainees, framing Selene for the atrocity. With Selene in her power, Semira begins draining her blood, which she intends to drink to steal her power. Thomas and David attempt a rescue, but are attacked by Semira and Varga. Thomas is killed, but David and Selene escape. The pair takes refuge at the Nordic Coven, pursued by Alexia, an Eastern Coven vampire dispatched by Semira. At Var Dohr, the Nordic Coven stronghold, Elder Vidar reveals that David is the son of High Elder Amelia, and thus the legitimate heir to the Eastern Coven. Meanwhile, Alexia has told Marius, who is secretly her lover, that Selene is going to the Nordic Coven. Marius and his Lycans attack that coven. Selene and David fight alongside the Nordic vampires, who are led by Vidar's daughter Lena. Selene engages Marius in single combat, but he is too powerful in werewolf form, and she is stabbed by Alexia. Marius demands to know Eve's location, but Selene insists she does not know; Alexia confirms this after tasting blood from her sword. Marius sounds the retreat. Selene deliberately slides herself under the now broken ice of the lake, telling herself that this is the 'path'., can you guess it ?
