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

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.

What do you do at a gym to lose weight?, Context: The style and role of any minority leader is influenced by a variety of elements, including personality and contextual factors, such as the size and cohesion of the minority party, whether his or her party controls the White House, the general political climate in the House, and the controversy that is sometimes associated with the legislative agenda. Despite the variability of these factors, there are a number of institutional obligations associated with this position. Many of these assignments or roles are spelled out in the House rule book. Others have devolved upon the position in other ways. To be sure, the minority leader is provided with extra staff resources—beyond those accorded him or her as a Representative—to assist in carrying out diverse leadership functions. Worth emphasis is that there are limits on the institutional role of the minority leader, because the majority party exercises disproportionate influence over the agenda, partisan ratios on committees, staff resources, administrative operations, and the day-to-day schedule and management of floor activities.

Where were vocals added to the piano music?, Context: In London Chopin took lodgings at Dover Street, where the firm of Broadwood provided him with a grand piano. At his first engagement, on 15 May at Stafford House, the audience included Queen Victoria and Prince Albert. The Prince, who was himself a talented musician, moved close to the keyboard to view Chopin's technique. Broadwood also arranged concerts for him; among those attending were Thackeray and the singer Jenny Lind. Chopin was also sought after for piano lessons, for which he charged the high fee of one guinea (£1.05 in present British currency) per hour, and for private recitals for which the fee was 20 guineas. At a concert on 7 July he shared the platform with Viardot, who sang arrangements of some of his mazurkas to Spanish texts.
