Question: The axiom of foundation established that every set can be constructed from the bottom up in an ordered succession of steps by way of the principles of Zermelo and Fraenkel, in such a manner that if one set belongs to another then the first must necessarily come before the second in the succession, hence excluding the possibility of a set belonging to itself. To demonstrate that the addition of this new axiom to the others did not produce contradictions, von Neumann introduced a method of demonstration, called the method of inner models, which later became an essential instrument in set theory.
Try to answer this question if possible: What excluded a set from belonging to itself in set theory?
Answer: if one set belongs to another then the first must necessarily come before the second in the succession
Question: There is also a widespread view[vague][who?] that giving much more financial support to continuously cover the debt crisis or allow even higher budget deficits or debt levels would discourage the crisis states to implement necessary reforms to regain their competitiveness.[citation needed] There has also been a reluctance[citation needed] of financially stable eurozone states like Germany[citation needed] to further circumvent the no-bailout clause in the EU contracts and to generally take on the burden of financing or guaranteeing the debts of financially unstable or defaulting eurozone countries.[citation needed]

Question: On January 6, 2016, the league took over "ownership and operational control" of the Portland Thunder from its previous owners. The AFL stated this move was made after months of trying work out an arrangement "to provide financial and operational support." On February 3, 2016, it was announced that the franchise will start from scratch and no longer be called the "Thunder" as the name and trademarks belong to former franchise owner Terry Emmert (similar to the Jerry Jones move with the Desperados). AFL commissioner Scott Butera announced that a new identity will be announced at a later date.
Try to answer this question if possible: Who is commissioner of the Arena Football League?
Answer: Scott Butera
