Question: Which of the two Stevenage players who were first transferred out during 2011-2012 season was born first? 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:Ahead of the club's first season in League One, Westley adopted the same "five in, five out" transfer policy as he had done for the two previous seasons. Strikers Yemi Odubade and Charlie Griffin were the first to leave having been loaned out for much of the previous campaign, joining Conference National sides Gateshead and Forest Green Rovers respectively. Second choice goalkeeper Ashley Bayes opted to leave the club in order to play first-team football at Conference South club Basingstoke Town. Luke Foster and David Bridges also opted to leave Stevenage ahead of the season, both on free transfers, with Foster signing for Rotherham United, and Bridges for his former club, Kettering Town. Stevenage's first signing of the season was striker Guy Madjo, who joined on a free transfer from Albanian Superliga side KS Bylis Ballsh. Former Stevenage goalkeeper Alan Julian re-joined the club following his release by Gillingham, while Phil Edwards rejected a contract extension at Accrington Stanley in order to join the Hertfordshire club on a free transfer. Midfielders Jennison Myrie-Williams and Robin Shroot also signed on free transfers following successful trial periods with the club. In terms of transfers during the 2011–12 campaign, striker Don Cowan joined the club from Longford Town for an undisclosed fee in August 2011, and winger Luke Freeman signed from Arsenal in January 2012, after a successful three-month loan spell with the club. Strikers Byron Harrison and Guy Madjo both departed in January 2012, signing for League Two sides AFC Wimbledon and Aldershot Town for respective undisclosed fees.
 Passage 3: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.

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.

Question: How long had Charles V been Emperor of the Holy Roman Empire for the year he signed the Treaty of Speyer? Passage 1:Scottish field armies rarely managed to stand up to the usually larger and more professional armies produced by England, but they were used to good effect by Robert I of Scotland at the Battle of Bannockburn in 1314 to secure Scottish independence. He adopted a policy of slighting castles and made use of naval power to support his forces, beginning to develop a royal Scottish naval force. In the Late Middle Ages under the Stewart kings these forces were further augmented by specialist troops, particularly men-at-arms and archers, hired by bonds of manrent, similar to English indentures of the same period. New "livery and maintenance" castles were built to house these troops and castles began to be adapted to accommodate gunpowder weapons. The Stewarts also adopted major innovations in continental warfare, such as longer pikes, the extensive use of artillery, and they built up a formidable navy. However, one of the best armed and largest Scottish armies ever assembled still met with defeat at the hands of an English army at the Battle of Flodden in 1513, which saw the destruction of a large number of ordinary troops, a large section of the nobility and King James IV.

 Passage 3:The Treaty of Speyer or Peace of Speyer was signed on May 23, 1544 between Denmark-Norway and the Holy Roman Empire during an Imperial Diet of the Holy Roman Empire in Speyer, Germany. Danish-Norwegian king Christian III had imposed heavy tolls on the Sound and two other channels between the North Sea and the Baltic sea, in an effort to end the Dutch dominance of trade in the Baltic region. Under pressure from Holy Roman Emperor Charles V, he agreed to exempt the Dutch ships from these tolls and give them free and unfettered access to the Baltic. In the treaty, Charles V also recognized Christian III as the rightful king of Denmark and Norway, and promised not to provide military support to his rival Christian II. The Treaty of Speyer dictated Christian III's foreign policy for the rest of his life. He kept Denmark-Norway at peace, refusing to involve the countries in Protestant-Catholic conflicts such as the Schmalkaldic War of 1546. The Dutch would continue to dominate Baltic trade for another two centuries.
