Problem: A wrestler can win by knockout (sometimes referred to as a referee stoppage) if they do not resort to submission holds, but stills pummels their opponent to the point that they are unconscious or are unable to intelligently defend themselves. To check for a knockout in this manner, a referee will wave their hand in front of the wrestler's face; if the wrestler does not react in any way, the referee will award the victory to the other wrestler. If all the active wrestlers in a match are down inside the ring at the same time, the referee will begin a count (usually ten seconds, twenty in Japan). If nobody rises to their feet by the end of the count, the match is ruled a draw. Any participant who stands up in time will end the count for everyone else. In a Last Man Standing match, this form of a knockout is the only way that the match can end, so the referee will count when one or more wrestlers are down, and one wrestler standing up before the 10-count doesn't stop the count for another wrestler who is still down.
How does a referee check for a knockout?
The answer is the following: a referee will wave their hand in front of the wrestler's face

Problem: John's royal household was based around several groups of followers. One group was the familiares regis, John's immediate friends and knights who travelled around the country with him. They also played an important role in organising and leading military campaigns. Another section of royal followers were the curia regis; these curiales were the senior officials and agents of the king and were essential to his day-to-day rule. Being a member of these inner circles brought huge advantages, as it was easier to gain favours from the king, file lawsuits, marry a wealthy heiress or have one's debts remitted. By the time of Henry II, these posts were increasingly being filled by "new men" from outside the normal ranks of the barons. This intensified under John's rule, with many lesser nobles arriving from the continent to take up positions at court; many were mercenary leaders from Poitou. These men included soldiers who would become infamous in England for their uncivilised behaviour, including Falkes de Breauté, Geard d'Athies, Engelard de Cigongé and Philip Marc. Many barons perceived the king's household as what Ralph Turner has characterised as a "narrow clique enjoying royal favour at barons' expense" staffed by men of lesser status.
Who were the curia regis?
The answer is the following: senior officials and agents of the king

Problem: The German Renaissance has bequeathed the city some noteworthy buildings (especially the current Chambre de commerce et d'industrie, former town hall, on Place Gutenberg), as did the French Baroque and Classicism with several hôtels particuliers (i.e. palaces), among which the Palais Rohan (1742, now housing three museums) is the most spectacular. Other buildings of its kind are the "Hôtel de Hanau" (1736, now the city hall), the Hôtel de Klinglin (1736, now residence of the préfet), the Hôtel des Deux-Ponts (1755, now residence of the military governor), the Hôtel d'Andlau-Klinglin (1725, now seat of the administration of the Port autonome de Strasbourg) etc. The largest baroque building of Strasbourg though is the 150 m (490 ft) long 1720s main building of the Hôpital civil. As for French Neo-classicism, it is the Opera House on Place Broglie that most prestigiously represents this style.
Where is the Opera House located?
