In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Example Input: The opposite of blackness is?, Context: The US racial or ethnic classification "black" refers to people with all possible kinds of skin pigmentation, from the darkest through to the very lightest skin colors, including albinos, if they are believed by others to have West African ancestry (in any discernible percentage), or to exhibit cultural traits associated with being "African American". As a result, in the United States the term "black people" is not an indicator of skin color or ethnic origin but is instead a socially based racial classification related to being African American, with a family history associated with institutionalized slavery. Relatively dark-skinned people can be classified as white if they fulfill other social criteria of "whiteness", and relatively light-skinned people can be classified as black if they fulfill the social criteria for "blackness" in a particular setting.
Example Output: whiteness

Example Input: Which of the following is not a dog tail shape: straight, sickle, or Braque du Bourbonnais?, Context: There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state, which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries. In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.
Example Output: Braque du Bourbonnais

Example Input: How vain was Rousseau?, Context: In November 1790, François-Louis-Thibault de Menonville, a member of the National Assembly of France, wrote to Burke, praising Reflections and requesting more "very refreshing mental food" that he could publish. This Burke did in April 1791 when he published A Letter to a Member of the National Assembly. Burke called for external forces to reverse the revolution and included an attack on the late French philosopher Jean-Jacques Rousseau, as being the subject of a personality cult that had developed in revolutionary France. Although Burke conceded that Rousseau sometimes showed "a considerable insight into human nature" he mostly was critical. Although he did not meet Rousseau on his visit to Britain in 1766–7 Burke was a friend of David Hume, with whom Rousseau had stayed. Burke said Rousseau "entertained no principle either to influence of his heart, or to guide his understanding—but vanity"—which he "was possessed to a degree little short of madness". He also cited Rousseau's Confessions as evidence that Rousseau had a life of "obscure and vulgar vices" that was not "chequered, or spotted here and there, with virtues, or even distinguished by a single good action". Burke contrasted Rousseau's theory of universal benevolence and his having sent his children to a foundling hospital: "a lover of his kind, but a hater of his kindred".
Example Output:
possessed to a degree little short of madness
