Passage 1:From 1 September – 7 October 1939 Geyr commanded the 3rd Panzer Division during the invasion of Poland, where it was the most numerically powerful Panzer Division, with 391 tanks.

He was promoted to General der Kavallerie of the XXIV Panzer Corps on 15 February 1940. In 1940 he commanded the XXIV Panzer Corps in the Invasion of France. In 1941, in the invasion of the Soviet Union, Geyr’s XXIV Panzer Corps was part of General Heinz Guderian’s Second Panzer Army, and consisted of all of Guderian's major tank units. On 9 July 1941, he was awarded the Knight's Cross of the Iron Cross as General der Panzertruppe. By early November 1941, Geyr's Panzer Corps commanded the 3rd, 4th, and 17th Panzer Divisions, the panzer regiment from the 18th Panzer Division, as well as the Infantry Regiment Großdeutschland, and spearheaded the advance of Army Group Centre during the Battle of Moscow.
 Passage 2:Menor was drafted 7th overall by the Barako Bull Energy Boosters in the 2009 PBA draft. He was then traded to the now-defunct Sta. Lucia Realtors and later played for the Meralco Bolts. He was waived by the team during the 2011 PBA Commissioner's Cup. Due to injuries to key players Mark Cardona and Chris Ross, Menor was re-signed by the Bolts. He was later traded to the Powerade Tigers during the off-season along with Chris Timberlake. However, he was not signed. He was then signed by the Clickers before the start of the season. In 2014, Menor played for expansion team Blackwater Elite for the 2014-15 season. Menor gained widespread attention on his 'butiki' (lizard in English) haircut that it even reached global attention from several sports websites around the world like ESPN and Bleacher Report.
 Passage 3:From November 26, 1943 to April 9, 1945, Seitz commanded the 26th Infantry Regiment (organized for the 1944-1945 campaign in France, Belgium and Germany as Regimental Combat Team 26 or Combat Team (CT) 26). CT 26 was a unit of the 1st Infantry Division (United States). Seitz commanded the combat team at Omaha Beach during the Normandy landings on D-Day, in the breakout from Normandy and at the approach to close the gap in the Falaise Pocket. The First United States Army, including Seitz's regimental combat team, hotly pursued the fleeing German Army divisions across France to the border of Germany by September 7, 1944. On October 11, 1944, after heavy fighting during the Battle of Aachen, Seitz led two of the three battalions of the regiment into heavily defended Aachen, Germany. They seized the first German city to fall to the Allies of World War II after 8 days of urban combat. In November 1944, Seitz led the regiment during the opening phase of the Battle of Hürtgen Forest. Starting only 10 days after the regiment was withdrawn from this bloody and costly battle, Seitz directed CT 26's heroic, successful stand at the Battle of Bütgenbach, an important part of the Battle of the Bulge that followed the Battle of Elsenborn Ridge. With many replacement soldiers due to losses in the Hürtgen Forest, and with skillful artillery support, Seitz and the outnumbered 26th Infantry Regiment team prevented the Nazi 12th SS Panzer Division Hitlerjugend, 3rd Parachute Division (Germany) and the 12th Volksgrenadier Division, which were supported by dozens of tanks, from breaking the Allied line at Bütgenbach.

 Passage 2:Mušicki was stationed in Slavonski Brod at the time of the Axis invasion of Yugoslavia in April 1941 and served as the Royal Yugoslav Army commander responsible for the railroad between Belgrade and Zagreb in the rank of colonel. He demonstrated his support for the Germans by helping their forces during the invasion. Yugoslavia was quickly conquered by the Axis powers and Mušicki remained in Slavonski Brod for several months after the conquest. He attempted to join the Ustaše Militia there, but was rejected. He went to Belgrade in mid-August, where he was received by Zbor leader Dimitrije Ljotić. On 6 October, Milan Nedić, the Prime Minister of the Axis-installed puppet Government of National Salvation, appointed Mušicki to lead the Serbian Volunteer Command (, SDK). Mušicki was involved in executing Serb civilians in the town of Čačak in December 1941. He and Milan Aćimović contacted Chetnik leader Draža Mihailović on 5 December, possibly in an effort to warn him in advance of the assault the Germans had planned, codenamed Operation Mihailovic. This action prompted the Germans to question Mušicki's loyalty. He was removed from command at the end of 1941 and imprisoned by the Germans, but was later freed at Nedić's intervention.
 Passage 3:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.

 Passage 3:Prior to the 2016 Contest, Georgia had participated in the Eurovision Song Contest eight times since their first entry in 2007. The nation's highest placing in the contest, to this point, has been ninth place, which was achieved on two occasions: in 2010 with the song "Shine" performed by Sofia Nizharadze and in 2011 with the song "One More Day" performed by Eldrine. The nation briefly withdrew from the contest in 2009 after the European Broadcasting Union (EBU) rejected the Georgian entry, "We Don't Wanna Put In", for perceived political references to Vladimir Putin who was the Russian Prime Minister at the time. The withdrawal and fallout was tied to tense relations between Georgia and then host country Russia, which stemmed from the 2008 Russo-Georgian War. Following the introduction of semi-finals, Georgia has, to this point, failed to qualify to the final on only two occasions. In , Georgia qualified to the final where the country placed 11th with the song "Warrior" performed by Nina Sublatti.
