Q: Question: How many bands competed in the Union Grove Fiddler's Convention competition against John Herald and his band? Passage:In 1958, Herald formed The Greenbriar Boys, along with Bob Yellin (banjo) and Paul Prestopino (mandolin). The following year, Eric Weissberg (mandolin and fiddle), replaced Prestopino, and Weissberg was soon replaced by Ralph Rinzler (mandolin) to form their most successful combination. Herald was lead guitarist and vocalist. The trio often played the Greenwich Village scene, but were notable enough to be the first Northern group to win the likes of the Union Grove Fiddler's Convention competition, where Yellin also took top honors for banjo. Shortly after backing Joan Baez on her second LP, The Greenbriar Boys were signed to Vanguard Records, for whom they released three records. In 1969, Linda Ronstadt recorded Herald's "High Muddy Water." Two years previously, she had recreated his vocal of Mike Nesmith's "Different Drum," which became a hit for her band the Stone Poneys.

Q: Question: How many square miles in size is the country that Russian Empress Catherine the Great laid out plans to incite revolts across? Passage:With the outbreak of the Russo-Turkish War in August 1787, Russian Empress Catherine the Great laid out her plans to incite revolts across Ottoman Greece. Proclamations calling the Greek clergy to lead a war of liberation against the Ottomans were printed in September 1787 and February 1788. In March, Admiral Samuel Greig and Major-General Ivan Zaborovsky were tasked with signing alliances and facilitating revolts among the Christian populations in Dalmatia, Albania and Greece. The Russian consulate in the Heptanese activated its network of sleeper agents who had originally been recruited before the Orlov revolt. Louitzis Sotiris and Himariot Panos Bitsilis begin recruiting soldiers in the area of Epirus, while Antonis Psaros and Lambros Katsonis built a small naval force in Italy. For the most part Russian plans did not materialize as the Baltic Fleet failed to reach the Mediterranean Sea. Without its assistance most of Russia's local allies refused to take part in the rising.

A: With the outbreak of the Russo-Turkish War in August 1787, Russian Empress Catherine the Great laid out her plans to incite revolts across Ottoman Greece

Q: Question: At what age was the Countess von Gelichen's brother when he inherited his cousin's Marquesstate of Hertford in 1870? Passage:When the Countess von Gleichen's brother, Francis, inherited his cousin's Marquessate of Hertford in 1870, the Queen granted her the rank and style of the daughter of a marquess by Royal Warrant of Precedence, entitling her to prefix Lady to her name. However, she continued to use her comital title until 15 December 1885, when it was gazetted in the Court Circular that the Queen had granted her permission to share, within the British Empire, her husband's princely title. Henceforth she was known as HSH Princess Victor of Hohenlohe-Langenburg, although this changed neither her legal rank nor her title in the German Empire. In accordance with the original Coburg grant, her children were also Count/Countess von Gleichen and, although granted unique precedence before the daughters and younger sons of English dukes in 1913, they never received authorisation to share their parents' princely style at the Court of St. James's, and were known by their comital title (dropping, however, the von) until George V Anglicised their style in 1917, along with the styles of members of his own family who bore German titles. Princess Victor did not live to undergo that demotion in titulature.
