[EX Q]: Question: Were the Vuippens and Holy Romans allied? Passage:Gummenen Castle, of which nothing remains, was built by either the Counts of Burgundy or the Dukes of Zahringen as part of the defenses along the Saane, along with Laupen Castle and Grasburg Castle. The castle was built to defend a bridge over the river. By 1391, a village (villa inferiori Dicti castri) had developed around the bridge. In 1259, Peter of Savoy made Gummenen into an imperial fief and imperial castellans took over the castle and village. In 128283 King Rudolph I of Germany forced the Savoy castellan out and granted it to a Habsburg knight, Ulrich II of Maggenberg as a fief. Ulrich's heirs sold the castle, ferry and ford to Fribourg in 1319. Fribourg then granted the lands to the knights of Vuippens, who lost it back to either the Holy Roman Empire or Fribourg in 1325. The castle and village were besieged and destroyed in 1333 during Bern and Fribourg's first war over the Sense and Saane valleys, the Gummenenkrieg. The peace treaty brokered in 1333 by Queen Agnes returned Gummenen to Fribourg.

[EX Q]: Question: Which opera house Easterlin has performed in during his career is the oldest? Passage:Easterlin received his Bachelor of Music degree from the University of Miami and his Bachelor of Science degree from Florida International University, and after a successful career in corporate advertising, began his performing career in musical theatre before moving into opera. He went on to perform at many of America's leading opera houses and festivals, including the Lyric Opera of Chicago, San Francisco Opera, Los Angeles Opera, Seattle Opera, New York City Opera, Dallas Opera, the Opera Company of Philadelphia, the Ravinia Festival with the Chicago Symphony conducted by Daniel Barenboim for the opening night of the Centennial Season, and Spoleto Festival USA in a new production of Ariadne auf Naxos conducted by Emmanual Villaume. He made his debut at the Glimmerglass Opera Festival in the summer of 2009 as 'The Magician' in a new production of Menotti's The Consul. According to Opera News, Easterlin spent 200 hours learning magic tricks for this production, which included producing a live rabbit on stage. Another unusual role for him was Houston Grand Opera's 2006 all-puppet production of Humperdinck's opera Hansel and Gretel in which he sang the role of the Witch as well as operating her twelve-foot high puppet.

[EX Q]: Question: Do the large bees that visit corn tassels often sting people? Passage:Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains.
