Problem: Information:  - Violin is a novel by American horror writer Anne Rice , released on 15 October 1997 . It moves away from her previous stories about vampires and witches to tell a ghost story .  - Christian literature is writing that deals with Christian themes and incorporates the Christian world view. This constitutes a huge body of extremely varied writing.  - Gothic fiction, which is largely known by the subgenre of Gothic horror, is a genre or mode of literature and film that combines fiction and horror, death, and at times romance. Its origin is attributed to English author Horace Walpole, with his 1764 novel "The Castle of Otranto", subtitled (in its second edition) "A Gothic Story." The effect of Gothic fiction feeds on a pleasing sort of terror, an extension of Romantic literary pleasures that were relatively new at the time of Walpole's novel. It originated in England in the second half of the 18th century and had much success in the 19th, as witnessed by Mary Shelleys "Frankenstein" and the works of Edgar Allan Poe. Another well known novel in this genre, dating from the late Victorian era, is Bram Stokers "Dracula". The name "Gothic" refers to the (pseudo)-medieval buildings, emulating Gothic architecture, in which many of these stories take place. This extreme form of romanticism was very popular in England and Germany. The English Gothic novel also led to new novel types such as the German "Schauerroman" and the French "Georgia".  - Interview with the Vampire is a debut gothic horror and vampire novel by American author Anne Rice, published in 1976. Based on a short story Rice wrote around 1968, the novel centers on vampire Louis de Pointe du Lac, who tells the story of his life to a reporter. Rice composed the novel shortly after the death of her young daughter Michelle, who served as an inspiration for the child-vampire character Claudia. Though initially the subject of mixed critical reception, the book was followed by a large number of widely popular sequels, collectively known as "The Vampire Chronicles". A film adaptation was released in 1994, starring Brad Pitt and Tom Cruise, and the novel has been adapted as a comic three times.  - Anne Rice (born Howard Allen Frances O'Brien; October 4, 1941) is an American author of gothic fiction, Christian literature, and erotica. She is perhaps best known for her popular and influential series of novels, "The Vampire Chronicles", revolving around the central character of Lestat. Books from "The Vampire Chronicles" were the subject of two film adaptations, "Interview with the Vampire" in 1994, and "Queen of the Damned" in 2002.  - The Vampire Chronicles is a series of novels by Anne Rice that revolves around the fictional character Lestat de Lioncourt, a French nobleman turned into a vampire in the 18th century.  - Erotica (from the Greek , "eros" "desire") is any artistic work that deals substantively with erotically stimulating or sexually arousing subject matter. All forms of art may depict erotic content, including painting, sculpture, photography, drama, film, music or literature. Erotica has high-art aspirations, differentiating it from commercial pornography.    Given the paragraphs above, decide what entity has the relation 'main subject' with 'music'.

Problem: Information:  - Johan Sverdrup (30 July 1816  17 February 1892) was a Norwegian politician from the Liberal Party. He was the first Prime Minister of Norway after the introduction of parliamentarism. Sverdrup was Prime Minister from 1884 to 1889.  - A monarchy is a form of government in which a group, usually a family called the dynasty, embodies the country's national identity and one of its members, called the monarch, exercises a role of sovereignty. The actual power of the monarch may vary from purely symbolic (crowned republic), to partial and restricted ("constitutional" monarchy), to completely autocratic ("absolute" monarchy). Traditionally and in most cases, the monarch's post is inherited and lasts until death or abdication, but there are also elective monarchies where the monarch is elected. Each of these has variations: in some elected monarchies only those of certain pedigrees are, whereas many hereditary monarchies impose requirements regarding the religion, age, gender, mental capacity, and other factors. Occasionally this might create a situation of rival claimants whose legitimacy is subject to effective election. Finally, there have been cases where the term of a monarch's reign is either fixed in years or continues until certain goals are achieved: an invasion being repulsed, for instance. Thus there are widely divergent structures and traditions defining monarchy. Monarchy was the most common form of government until the 19th century, but it is no longer prevalent. Where it exists, it is now usually a constitutional monarchy, in which the monarch retains a unique legal and ceremonial role, but exercises limited or no official political power: under the written or unwritten constitution, others have governing authority. Currently, 47 sovereign nations in the world have monarchs acting as heads of state, 19 of which are Commonwealth realms that recognise Queen Elizabeth II as their head of state. All European monarchies are constitutional ones, with the exception of the Vatican City which is an elective monarchy, but sovereigns in the smaller states exercise greater political influence than in the larger. The monarchs of Cambodia, Japan, and Malaysia "reign, but do not rule" although there is considerable variation in the degree of...  - The Prime Minister of Norway (literally "state minister") is the political leader of Norway and the Head of the Government of Norway. The Prime Minister and Cabinet (consisting of all the most senior government department heads) are collectively accountable for their policies and actions to the Monarch, to the Storting (Parliament of Norway), to their political party, and ultimately the electorate. In practice, since it is nearly impossible for a government to stay in office against the will of the Storting, the Prime Minister is primarily answerable to the Storting.  - Parliamentary elections were held in Norway in 1885 . The result was a victory for the Liberal Party , which won 84 of the 114 seats in the Storting . Johan Sverdrup remained Prime Minister .  - Norway (; Norwegian: (Bokmål) or (Nynorsk); Sami: "Norgga"), officially the Kingdom of Norway, is a sovereign and unitary monarchy whose territory comprises the western portion of the Scandinavian Peninsula plus the island Jan Mayen and the archipelago of Svalbard. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the Kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land. Until 1814, the Kingdom included the Faroe Islands (since 1035), Greenland (1261), and Iceland (1262). It also included Shetland and Orkney until 1468. It also included the following provinces, now in Sweden: Jämtland, Härjedalen and Bohuslän.
