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

Ex 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.

Ex Output:
whiteness

Ex Input:
In what part of the country could you no longer watch a death penalty get carried out, Context: Around 1890, a political movement developed in the United States to mandate private executions. Several states enacted laws which required executions to be conducted within a "wall" or "enclosure" to "exclude public view." For example, in 1919, the Missouri legislature adopted a statute (L.1919, p. 781) which required, "the sentence of death should be executed within the county jail, if convenient, and otherwise within an enclosure near the jail." The Missouri law permitted the local sheriff to distribute passes to individuals (usually local citizens) whom he believed should witness the hanging, but the sheriffs – for various reasons – sometimes denied passes to individuals who wanted to watch. Missouri executions conducted after 1919 were not "public" because they were conducted behind closed walls, and the general public was not permitted to attend.

Ex Output:
Missouri
