Input: Read this: The Republic of Liberia, beginning as a settlement of the American Colonization Society (ACS), declared its independence on July 26, 1847. The United States did not recognize Liberia's independence until during the American Civil War on February 5, 1862. Between January 7, 1822 and the American Civil War, more than 15,000 freed and free-born Black Americans from United States and 3,198 Afro-Caribbeans relocated to the settlement. The Black American settlers carried their culture with them to Liberia. The Liberian constitution and flag were modeled after the United States. In January 3, 1848 Joseph Jenkins Roberts, a wealthy free-born Black American from Virginia who settled in Liberia, was elected as Liberia's first president after the people proclaimed independence.
Question: How many Liberians fled to the United States during the Civil War?

Output: unanswerable

Input: Read this: Internationally, Victoria took a keen interest in the improvement of relations between France and Britain. She made and hosted several visits between the British royal family and the House of Orleans, who were related by marriage through the Coburgs. In 1843 and 1845, she and Albert stayed with King Louis Philippe I at chateau d'Eu in Normandy; she was the first British or English monarch to visit a French one since the meeting of Henry VIII of England and Francis I of France on the Field of the Cloth of Gold in 1520. When Louis Philippe made a reciprocal trip in 1844, he became the first French king to visit a British sovereign. Louis Philippe was deposed in the revolutions of 1848, and fled to exile in England. At the height of a revolutionary scare in the United Kingdom in April 1848, Victoria and her family left London for the greater safety of Osborne House, a private estate on the Isle of Wight that they had purchased in 1845 and redeveloped. Demonstrations by Chartists and Irish nationalists failed to attract widespread support, and the scare died down without any major disturbances. Victoria's first visit to Ireland in 1849 was a public relations success, but it had no lasting impact or effect on the growth of Irish nationalism.
Question: Who didn't Victoria stay with in Normandy?

Output: unanswerable

Input: Read this: Although STOVL aircraft are capable of taking off vertically from a spot on the deck, using the ramp and a running start is far more fuel efficient and permits a heavier launch weight. As catapults are unnecessary, carriers with this arrangement reduce weight, complexity, and space needed for complex steam or electromagnetic launching equipment, vertical landing aircraft also remove the need for arresting cables and related hardware. Russian, Chinese, and future Indian carriers include a ski-jump ramp for launching lightly loaded conventional fighter aircraft but recover using traditional carrier arresting cables and a tailhook on their aircraft.
Question: What do Russian carriers no longer use to recover?

Output: unanswerable

Input: Read this: In higher organisms (like people), these two modes of perception combine into what Whitehead terms "symbolic reference", which links appearance with causation in a process that is so automatic that both people and animals have difficulty refraining from it. By way of illustration, Whitehead uses the example of a person's encounter with a chair. An ordinary person looks up, sees a colored shape, and immediately infers that it is a chair. However, an artist, Whitehead supposes, "might not have jumped to the notion of a chair", but instead "might have stopped at the mere contemplation of a beautiful color and a beautiful shape." This is not the normal human reaction; most people place objects in categories by habit and instinct, without even thinking about it. Moreover, animals do the same thing. Using the same example, Whitehead points out that a dog "would have acted immediately on the hypothesis of a chair and would have jumped onto it by way of using it as such." In this way symbolic reference is a fusion of pure sense perceptions on the one hand and causal relations on the other, and that it is in fact the causal relationships that dominate the more basic mentality (as the dog illustrates), while it is the sense perceptions which indicate a higher grade mentality (as the artist illustrates).
Question: How does Whitehead describe the process of a typical person noticing a chair?
