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: What has Utrecht Centraal railway on one side, and the city centre on the other side?, Context: A large indoor shopping centre Hoog Catharijne (nl) is located between Utrecht Centraal railway station and the city centre. The corridors are treated as public places like streets, and the route between the station and the city centre is open all night. In 20 years from 2004, parts of Hoog Catharijne will be redeveloped as part of the renovation of the larger station area. Parts of the city's network of canals, which were filled to create the shopping center and central station area, will be recreated. The Jaarbeurs, one of the largest convention centres in the Netherlands, is located at the west side of the central railway station.
Example Output: Hoog Catharijne

Example Input: What plant structure does cotton grow inside?, Context: Most cotton in the United States, Europe and Australia is harvested mechanically, either by a cotton picker, a machine that removes the cotton from the boll without damaging the cotton plant, or by a cotton stripper, which strips the entire boll off the plant. Cotton strippers are used in regions where it is too windy to grow picker varieties of cotton, and usually after application of a chemical defoliant or the natural defoliation that occurs after a freeze. Cotton is a perennial crop in the tropics, and without defoliation or freezing, the plant will continue to grow.
Example Output:
the boll
