[Q]: What was a upside to the altercation?, Context: On Saturday, July 23, 1989, much of America learned of the AFL for an unintended reason, when the Pittsburgh Gladiators' head coach, Joe Haering, made football history by punching commissioner Jim Foster during a game with the Chicago Bruisers. The national media ran with the story, including a photo in USA Today. The game was played between the two teams in Sacramento's Arco Arena, as part of the AFL's 'Barnstorming America' tour. Foster had walked onto the field of play to mediate an altercation between the two teams when Haering, a former NFL assistant, punched him in the jaw. Haering was suspended without pay.
[A]: much of America learned of the AFL


[Q]: What is needed to prove the theory?, Context: In the early 11th century, the Muslim physicist Ibn al-Haytham (Alhacen or Alhazen) discussed space perception and its epistemological implications in his Book of Optics (1021), he also rejected Aristotle's definition of topos (Physics IV) by way of geometric demonstrations and defined place as a mathematical spatial extension. His experimental proof of the intromission model of vision led to changes in the understanding of the visual perception of space, contrary to the previous emission theory of vision supported by Euclid and Ptolemy. In "tying the visual perception of space to prior bodily experience, Alhacen unequivocally rejected the intuitiveness of spatial perception and, therefore, the autonomy of vision. Without tangible notions of distance and size for correlation, sight can tell us next to nothing about such things."
[A]: vision


[Q]: Why did the Czech historians emphasize themselves?, Context: The Czech people gained widespread national pride during the mid-eighteenth century, inspired by the Age of Enlightenment a half-century earlier. Czech historians began to emphasize their people's accomplishments from the fifteenth through the seventeenth centuries, rebelling against the Counter-Reformation (which had denigrated Czech and other non-Latin languages). Czech philologists studied sixteenth-century texts, advocating the return of the language to high culture. This period is known as the Czech National Revival (or Renascence).
[A]:
the Counter-Reformation (which had denigrated Czech and other non-Latin languages)
