Input: Read this: In 1582 the United Provinces invited Francis, Duke of Anjou to lead them; but after a failed attempt to take Antwerp in 1583, the duke left the Netherlands again. After the assassination of William of Orange (10 July 1584), both Henry III of France and Elizabeth I of England declined the offer of sovereignty. However, the latter agreed to turn the United Provinces into a protectorate of England (Treaty of Nonsuch, 1585), and sent the Earl of Leicester as governor-general. This was unsuccessful and in 1588 the provinces became a confederacy. The Union of Utrecht is regarded as the foundation of the Republic of the Seven United Provinces, which was not recognized by the Spanish Empire until the Peace of Westphalia in 1648.
Question: In what year did the Duke of Anjou conquered the United provinces?

Output: unanswerable


Input: Read this: There is no universally accepted criterion for distinguishing two different languages from two dialects (i.e. varieties) of the same language. A number of rough measures exist, sometimes leading to contradictory results. The distinction is therefore subjective and depends on the user's frame of reference. For example, there is discussion about if the Limón Creole English must be considered as "a kind" of English or a different language. This creole is spoken in the Caribbean coast of Costa Rica (Central America) by descendant of Jamaican people. The position that Costa Rican linguists support depends on the University they belong.
Question: How many universally accepted criterion for distinguishing between two languages from two dialects are there?

Output: unanswerable


Input: Read this: In March 1861, Victoria's mother died, with Victoria at her side. Through reading her mother's papers, Victoria discovered that her mother had loved her deeply; she was heart-broken, and blamed Conroy and Lehzen for "wickedly" estranging her from her mother. To relieve his wife during her intense and deep grief, Albert took on most of her duties, despite being ill himself with chronic stomach trouble. In August, Victoria and Albert visited their son, the Prince of Wales, who was attending army manoeuvres near Dublin, and spent a few days holidaying in Killarney. In November, Albert was made aware of gossip that his son had slept with an actress in Ireland. Appalled, Albert travelled to Cambridge, where his son was studying, to confront him. By the beginning of December, Albert was very unwell. He was diagnosed with typhoid fever by William Jenner, and died on 14 December 1861. Victoria was devastated. She blamed her husband's death on worry over the Prince of Wales's philandering. He had been "killed by that dreadful business", she said. She entered a state of mourning and wore black for the remainder of her life. She avoided public appearances, and rarely set foot in London in the following years. Her seclusion earned her the nickname "widow of Windsor".
Question: Who did Victoria blame for Prince Albert's death?

Output: their son, the Prince of Wales


Input: Read this: Architects such as Mies van der Rohe, Philip Johnson and Marcel Breuer worked to create beauty based on the inherent qualities of building materials and modern construction techniques, trading traditional historic forms for simplified geometric forms, celebrating the new means and methods made possible by the Industrial Revolution, including steel-frame construction, which gave birth to high-rise superstructures. By mid-century, Modernism had morphed into the International Style, an aesthetic epitomized in many ways by the Twin Towers of New York's World Trade Center designed by Minoru Yamasaki.
