Hunyadi succeeded during the Siege of Belgrade in 1456 against the Ottomans, the biggest victory against that empire in decades. This battle became a real Crusade against the Muslims, as the peasants were motivated by the Franciscan monk Saint John of Capistrano, who came from Italy predicating Holy War. The effect that it created in that time was one of the main factors that helped in achieving the victory. However the premature death of the Hungarian Lord left Pannonia defenseless and in chaos. In an extremely unusual event for the Middle Ages, Hunyadi's son, Matthias, was elected as King of Hungary by the nobility. For the first time, a member of an aristocratic family (and not from a royal family) was crowned.
When John Hunyadi died, which province was left in chaos?
A: Pannonia

A number of meta-analyses have found clinical hypnosis to be effective in controlling pain associated with diagnostic and surgical procedures in both adults and children, as well as pain associated with cancer and childbirth. A 2007 review of 13 studies found evidence for the efficacy of hypnosis in the reduction of chronic pain in some conditions, though the number of patients enrolled in the studies was low, bringing up issues of power to detect group differences, and most lacked credible controls for placebo and/or expectation. The authors concluded that "although the findings provide support for the general applicability of hypnosis in the treatment of chronic pain, considerably more research will be needed to fully determine the effects of hypnosis for different chronic-pain conditions."
What is considerable more research needed to determine for different chronic pain conditions?
A: effects of hypnosis

Some of the best-known traditions, including carnal parades and masquerade balls, were first recorded in medieval Italy. The carnival of Venice was, for a long time, the most famous carnival (although Napoleon abolished it in 1797 and only in 1979 was the tradition restored). From Italy, Carnival traditions spread to Spain, Portugal and France and from France to New France in North America. From Spain and Portugal it spread with colonization to the Caribbean and Latin America. In the early 19th century in the German Rhineland and Southern Netherlands, the weakened medieval tradition also revive. Continuously in the 18th and 19th centuries CE, as part of the annual Saturnalia abuse of the carnival in Rome, rabbis of the ghetto were forced to march through the city streets wearing foolish guise, jeered upon and pelted by a variety of missiles from the crowd. A petition of the Jewish community of Rome sent in 1836 to Pope Gregory XVI to stop the annual anti-semitic Saturnalia abuse got a negation: "It is not opportune to make any innovation."
What city's carnival was the most famous for a long time?

Venice
