Passage: Since about 560, the Avars had ruled over large parts of the Pannonian Basin and Carantania southeast of Francia, though in the last decades, the Avar Khaganate had to deal with Bulgarian and Croat incursions. To secure the frontier of his empire and the traffic on the trade routes to the east, Charlemagne allied with Khan Krum of Bulgaria and the Croatian duke Vojnomir, and from 791 launched several campaigns against the Avars, where he, according to the Vita Karoli Magni, encountered only modest opposition. In 796 Carolingian forces under Charlemagne's son Pepin of Italy destroyed the main Avar fortress called the Ring of the Avars and made the Khagan a Frankish vassal, while the remaining Avars retreated behind the Tisza River. The victory is perpetuated by the poem De Pippini regis Victoria Avarica.

Passage: SMS Kronprinzessin Erzherzogin Stephanie was an ironclad warship built for the Austro-Hungarian Navy in the 1880s, the last vessel of that type to be built for Austria-Hungary. The ship, named for Archduchess Stephanie, Crown Princess of Austria, was laid down in November 1884, was launched in April 1887 and completed in July 1889. She was armed with a pair of guns in open barbettes and had a top speed of . Her service was limited, in large part due to the rapid pace of naval development in the 1890s, which quickly rendered her obsolescent. As a result, her career was generally limited to routine training and the occasional visit to foreign countries. In 1897, she took part in an international naval demonstration to force a compromise over Greek and Ottoman claims to the island of Crete. Kronprinzessin Erzherzogin Stephanie was decommissioned in 1905, hulked in 1910, and converted into a barracks ship in 1914. After Austria-Hungary's defeat in World War I, the ship was transferred to Italy as a war prize and was eventually broken up for scrap in 1926.

Ex Output:
How long did the global conflict where Austria-Hungary was defeated last?

Passage: Although in 2008 Baseball America projected Venable as an every day starter for the Padres in 2010, some experts questioned whether he would be a long-term solution in center field for the team. Venable started the 2009 season with the Padres' Triple-A affiliate, Portland Beavers, but he was recalled by the Padres on June 3. His father, Max, served as the Beavers' hitting coach in 2009. Following the July 5 trade of Scott Hairston to the Oakland Athletics, Venable shared right field with Kyle Blanks. On July 12 against the San Francisco Giants, he had his first home run of the season in his first career four-hit game. Between July 30 and August 5, he homered in five of seven games. In an August 23 game against the St. Louis Cardinals, he was involved in a bench-clearing incident when Albert Pujols thought he threw an elbow while being tagged out. In 2009, he posted 12 home runs and tallied 38 runs batted in (RBI), while defensively 493.2 of his 643 innings were spent in right field and only 117 in center field.
 Link Information: thought he threw an elbow while being tagged out. Answer: Kyle Blanks

Ex Output:
