Q: Question: How many corners can be found on a gaff-rigged vessel sail? Passage 1:During the first week of September 1861, all pretense of neutrality in Kentucky ended when Maj. Gen. Leonidas Polk ordered Brig. Gen. Gideon Pillow advance Confederate troops up to Hickman, Kentucky. On September 18, Kentucky legislature approved the introduction of Federal troops from outside the state, the pro-Confederate legislators staying away. The next day, Simon Bolivar Buckner, former commander of the Kentucky State Guard, established a Confederate headquarters at Bowling Green, Kentucky, while troops under Felix K. Zollicoffer seized Barbourville. Shortly afterwards, Zollicoffer arrived at Cumberland Ford with approximately 3,200 men, consisting of four infantry regiments, a field battery of six guns, and four cavalry companies. This posed an imminent threat to Union control of central Kentucky, at a time when increasing numbers of Confederates in the Big Sandy Valley of eastern Kentucky appeared about to enter the Bluegrass region through McCormack's Gap (Frenchburg). In response, Brig. Gen. George H. Thomas ordered troops from Camp Dick Robinson to southeast Kentucky to halt any movement toward Big Hill, Richmond and Lexington. Former Vice President of the United States John C. Breckinridge and his ally, Col. Humphrey Marshall, added to Thomas's concerns with a call for "Peace Men" and "States' Rights Men" to assemble in Lexington for drill. However, both Breckinridge and Marshall instead rode to Mt. Sterling to join the Confederate forces in western Virginia, where Marshall took command of the Army of Eastern Kentucky posted at Piketon (Pikeville).
 Passage 2:He adopted "Danish" as his Takhallus (pen-name). Bachay, Titli, Phool, his first collection of poems, was published in 1997. He quickly garnered recognition for the anger he expressed through his works, in which he often made reference to his experiences as a member of the African diaspora; his work attracted the attention of leading Urdu critic Shamsur Rahman Farooqi, who had them published in Indian literary journal Shabkhoon. In 2000, he emigrated to the United States; he had remarked to a friend that he would prefer to be "a third class citizen of a first class country than a first class citizen of a third class country," but put off going through the procedures for almost two years due to his ambivalence about leaving his home. He first took up residence in the Kew Gardens neighborhood of Queens, New York City; he chose it because of its diversity, which helped him to feel less of a stranger as well as affording him the opportunity to study others' cultures. At first, he could only find job as a security guard, but he eventually joined the faculty of New York University; he later moved to the University of Maryland as a language consultant.
 Passage 3:Running rigging is the cordage used to control the shape and position of the sails. Materials have evolved from the use of Manilla rope to synthetic fibers, which include dacron, nylon and kevlar. Running rigging varies between fore-and-aft rigged vessels and square-rigged vessels. They have common functions between them for supporting, shaping and orienting sails, which employ different mechanisms. For supporting sails, halyards (sometimes haulyards), are used to raise sails and control luff tension. On gaff-rigged vessels, topping lifts hold the yards across the top of the sail aloft. Sail shape is usually controlled by lines that pull at the corners of the sail, including the outhaul at the clew and the downhaul at the tack on fore-and-aft rigs. The orientation of sails to the wind is controlled primarily by sheets, but also by braces, which position the yard arms with respect to the wind on square-rigged vessels.
