Problem: Question: "What determines the category?" Context: "The "soft" AC format has reinvented in the late 2000s/early 2010s as a result of its declining relevance, adopting a more upmarket, middle-of-the-road approach, with a selection of "oldies" (usually from the 1960s/70s onwards), primarily rock, jazz, R&B and pop music. Newer songs are more often (but not limited to) "easy listening" fare, this amount varying depending on the age of the station's target demographic." Answer:

A: the age of the station's target demographic

Problem: Question: "The Persians ruled Egypt in fifth century what?" Context: "In 525 BC, the powerful Achaemenid Persians, led by Cambyses II, began their conquest of Egypt, eventually capturing the pharaoh Psamtik III at the battle of Pelusium. Cambyses II then assumed the formal title of pharaoh, but ruled Egypt from his home of Susa in Persia (modern Iran), leaving Egypt under the control of a satrapy. The entire Twenty-seventh Dynasty of Egypt, from 525 BC to 402 BC, save for Petubastis III, was an entirely Persian ruled period, with the Achaemenid kings all being granted the title of pharaoh. A few temporarily successful revolts against the Persians marked the fifth century BC, but Egypt was never able to permanently overthrow the Persians." Answer:

A: BC

Problem: Question: "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." Answer:

A: whiteness

Problem: Question: "What do good special referees do?" Context: "Special guest referees may be used from time to time; by virtue of their celebrity status, they are often scripted to dispense with the appearance of neutrality and use their influence to unfairly influence the outcome of the match for added dramatic impact. Face special referees will often fight back against hostile heel wrestlers, particularly if the special referee is either a wrestler themselves or a famous martial artist (such as Tito Ortiz in the main event at TNA's THard Justice in 2005). They also have the power to eject from ringside any of the heel wrestler's entourage/stable, who may otherwise interfere with the match." Answer:

A:
They also have the power to eject from ringside any of the heel wrestler's entourage/stable, who may otherwise interfere with the match
