Question: How long did the battle where Wilcke was shot down and taken prisoner last? Passage 1:Born in Pittsburgh, Pennsylvania, Lee was in the United States Navy in the aftermath of World War II, from 1945 to 1947. He received an Artium Baccalaureus degree from the University of Pittsburgh in 1950 and a Bachelor of Laws from Duquesne University School of Law in 1954. He was in private practice in Pittsburgh from 1954 to 1956. He was a law clerk for Judge Rabe Marsh of the United States District Court for the Western District of Pennsylvania from 1957 to 1958. He was in private practice in Pittsburgh from 1958 to 1984. He was a councilman of the Borough of Green Tree, Pennsylvania from 1961 to 1963. He was a special assistant state attorney general of Pennsylvania from 1963 to 1974. He was a Solicitor for the Borough of Green Tree, Pennsylvania from 1963 to 1984 and from 1986 to 1988.

 Passage 2:The film begins with a narrated map showing the Confederate Army of Northern Virginia, commanded by Robert E. Lee, crossing the Potomac River to invade the North in June 1863, marching across Maryland and into Pennsylvania. On June 30, Confederate spy Henry Thomas Harrison reports to Lt. Gen. James Longstreet, commander of the First Corps, that the Union Army of the Potomac is moving in their direction, and that Union commander Joseph Hooker has been replaced by George Meade. Longstreet reports the information to General Lee, who is concerned that the army is moving "on the word of an actor", as opposed to that of his cavalry chief, J. E. B. Stuart. Nonetheless, Lee orders the army to concentrate near the town of Gettysburg. At the Union encampments near Union Mills, Maryland, Col. Joshua Lawrence Chamberlain of the 20th Maine is ordered to take in 120 men from the disbanded 2nd Maine who had resigned in protest, with permission to shoot any man who refuses to fight. Chamberlain speaks to the men, and is able to persuade all but six to take up arms.
 Passage 3:Born in Schrimm in the Province of Posen, Wilcke volunteered for military service in the Reichswehr of the Third Reich in 1934. Initially serving in the Heer (Army), he transferred to the Luftwaffe (Air Force) in 1935. Following flight training, he was posted to Jagdgeschwader "Richthofen" (Fighter Wing "Richthofen") in April 1936. After an assignment as fighter pilot instructor he volunteered for service with the Condor Legion during the Spanish Civil War in early 1939. After his return from Spain, he was appointed Staffelkapitän (squadron leader) of the 7. Staffel (7th squadron) of Jagdgeschwader 53 (JG 53—53rd Fighter Wing). Following the outbreak of World War II, he claimed his first aerial victory on 7 November 1939. On 18 May 1940, during the Battle of France, he was shot down and taken prisoner of war. After the armistice with France, he returned from captivity and was appointed Gruppenkommandeur (group commander) of the III.

Question: Who was the commander of the Army of Tennessee during the siege of Vicksburg? Passage 1:Ryan supports eliminating the capital gains tax, the corporate income tax, the estate tax, and the Alternative Minimum Tax. In 1999, Ryan supported the Gramm–Leach–Bliley Act, which repealed some financial regulation of banks from the Glass–Steagall Act of 1933. During the economic recovery from the Great Recession of the late 2000s, Ryan supported the Troubled Asset Relief Program (TARP), which authorized the Treasury to purchase toxic assets from banks and other financial institutions, and the auto industry bailout; Ryan opposed the Credit CARD Act of 2009, which expanded consumer protections regarding credit card plans, and the Dodd–Frank Wall Street Reform and Consumer Protection Act, which strengthened financial regulation.
 Passage 2:He first appears in Constantinople in 1401, qualified as an oikeios of the emperor. In 1417 he was possibly sent on a diplomatic mission to the Venetians in the Morea. In 1422 and again in 1429 he was sent by Emperor John VIII Palaiologos as an envoy to the Ottoman Sultan Murad II. At the time he had the relatively lowly rank of protovestiarites, but was quickly promoted to protostrator and then to the senior rank of megas stratopedarches, which he held already during his mission in 1430 to Pope Martin V. During his return from the mission to the Pope, on orders from the Emperor, he raised Thomas Palaiologos to the rank of Despot in the Morea. He led two more missions abroad, one in 1433 to Pope Eugene IV, and one in 1438 to Venice.
 Passage 3:At the beginning of the Civil War, he became a lieutenant and adjutant of the 13th Iowa Infantry Regiment. He fought at the battle of Shiloh and Corinth. He served as assistant adjutant general in the XVII Corps during the siege of Vicksburg and assistant adjutant general to the Army of the Tennessee during the Atlanta Campaign. He was made a brevet brigadier general for service in the Atlanta Campaign and was assigned to an infantry brigade in the XV Corps during the Carolinas Campaign, but was only lightly engaged in fighting. He rose to the full rank of brigadier general of volunteers (1865), and was made a brevet major general at the close of the same year for gallant and meritorious services during the war.

Question: Was the French zoologist who included a description of the red-winged starling younger than the Swedish naturalist who later added that species to his Systema Naturae? Passage 1:In 1760 the French zoologist Mathurin Jacques Brisson included a description of the red-winged starling in his Ornithologie based on a specimen collected from the Cape of Good Hope in South Africa. He used the French name Le merle du Cap de Bonne Espérance and the Latin Merula Capitis Bonae Spei. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the red-winged starling. Linnaeus included a brief description, coined the binomial name Turdus morio and cited Brisson's work. The specific name morio or morion is Latin for "dark brown stone" or "black quartz". This species is now placed in the genus Onychognathus that was introduced by the German physician and ornithologist Gustav Hartlaub in 1849.
 Passage 2:Portree in the north at the base of Trotternish is the largest settlement (estimated population 2,264 in 2011) and is the main service centre on the island. Broadford, the location of the island's only airstrip, is on the east side of the island and Dunvegan in the north-west is well known for its castle and the nearby Three Chimneys restaurant. The 18th-century Stein Inn on the Waternish coast is the oldest pub on Skye. Kyleakin is linked to Kyle of Lochalsh on the mainland by the Skye Bridge, which spans the narrows of Loch Alsh. Uig, the port for ferries to the Outer Hebrides, is on the west of the Trotternish peninsula and Edinbane is between Dunvegan and Portree. Much of the rest of the population lives in crofting townships scattered around the coastline.
 Passage 3:Old Black is a 1953 Gibson Les Paul Goldtop, painted black and customized considerably. After the guitar had been left at a guitar repair store, the original P-90 bridge pickup was replaced with a Gretsch Dynasonic single-coil pickup. Eventually, a mini humbucker pickup from a Gibson Firebird guitar replaced the Dynasonic. The neck pickup has always been the original P-90 pickup, but it is now covered by a hand fitted aluminum P-90 cover, replacing the original white plastic cover. The guitar was roughly resprayed to jet black, and received a new Tune-o-matic bridge (not available when the guitar was produced) and a B-7 model Bigsby vibrato tailpiece. It would presumably also have had a white plastic pickguard at some point, as was standard on 1953 Goldtops. Old Black is notable for its metal hardware, including aluminum backing plates. The pick guard is chrome-on-brass/bronze. The tuners have been replaced with Schaller M-6 tuning keys, and the rest of the hardware is mostly nickel-plated. The headstock displays a partially painted-over mother-of-pearl inlay, sometimes referred to as a "wheat stack", rather than the typical silk screened "Les Paul Model" logo, along with single-ply binding around the headstock, although the binding has now fallen off.
