[EX Q]: Question: Which of the two units held in reserve had more soldiers? Passage 1:As designed in 1931, the He 46 was a two-seat sesquiplane of mixed construction. The upper wing was swept back 10°. This is a common trick when a change in an aircraft's design moves the center of gravity to the rear; rather than moving the whole wing back to counter for the shift, it is easier to simply angle the wings back slightly, which requires very little change to the basic design, or even the overall structure of the wing. (The similarly angled wings on the Fairey Swordfish are due to just such a mid-program change to the weight distribution of the aircraft.) The tailplane was mounted high and braced by struts. The undercarriage was fixed, and the tail was fitted with a skid rather than a wheel. The He 46 prototype first flew in late 1931; its flight characteristics were good, but design improvements were incorporated. The small lower wing was removed, while the mainplane was increased in area by 22% and braced to the fuselage, transforming the He 46 into a parasol-wing monoplane. A more powerful engine was added to the second prototype, and a single 7.92 mm (.312 in) MG 15 machine gun for the rear seat was added to the third prototype.
 Passage 2:In planning for the actual attack, Manteuffel had divided his 5th Panzer Army into three corps composed of infantry, tanks, and supporting artillery. The main effort, or schwerpunkt, would consist of XLVII Panzer Corps and LVIII Panzer Corps advancing west across the River Our at Ouren from the south or left flank of the German army front. They would then occupy the transportation center of Bastogne, before crossing the Meuse River at Namur. The third group, LXVI Corps, would advance west on either side of the Schnee Eifel. This northernmost, or right wing, element would flank and begin an envelopment of the American forces occupying fortifications on the Schnee Eifel and then converge on the town of Winterspelt. From there, LXVI Corps would cross the Our river and occupy St. Vith on the first day of the attack. LXVI Corps was the weakest of the three corps, with no attached tank division or motor transport, but did include an attached assault gun battalion. The Panzer Lehr Division (Armor Demonstration Division) and the Führer Begleit Brigade (Führer Escort Brigade) were to be held in reserve, with the Führer Begleit only usable with Model's express permission. Manteuffel's preference for the "little slam", or limited solution, was reflected in the absence of planning beyond reaching the Meuse River.
 Passage 3:On 7 October 1593, the superintendent of the Venetian Republic founded a revolutionary new kind of settlement: Palmanova. The city’s founding date commemorated the victory of the Christian forces (supplied primarily by the Italian states and the Spanish kingdom) over the Ottoman Turks in the Battle of Lepanto in 1571, during the War of Cyprus. Also honored on 7 October was Saint Justina, chosen as the city's patron saint. Using all the latest military innovations of the 16th century, this small town was a fortress in the shape of a nine-pointed star, designed by Vincenzo Scamozzi. Between the points of the star, ramparts protruded so that the points could defend each other. A moat surrounded the town, and three large, guarded gates allowed entry. The construction of the first circle, with a total circumference of , took 30 years. Marcantonio Barbaro headed a group of Venetian noblemen in charge of building the town, Marcantonio Martinego was in charge of construction, and Giulio Savorgnan acted as an adviser. A second phase of construction took place between 1658 and 1690, and the outer line of fortifications was completed between 1806 and 1813 under the Napoleonic domination. The final fortress consists of: 9 ravelins, 9 bastions, 9 lunettes, and 18 cavaliers.

[EX Q]: Question: Which Russia club that Laizans played for after he left CSKA Moscow had won championship? Passage 1:The Red Rovers, commonly referred to as the Alabama Red Rovers, was a filibuster force organized in Courtland, Alabama to support the Texas Revolution. Raised by doctor and planter Jack Shackelford in November 1835, the unit took its name from the red jeans of their uniforms and was outfitted with equipment from Alabama state arsenal. Consisting of some 70 men, nearly half the men in Courtland, the unit remained encamped until December 12 before setting out for Texas by way of New Orleans. After arriving at Lavaca Bay on January 19, 1836 and being accepted into Texas service on February 3, the Red Rovers were put under command of Colonel James W. Fannin. They fought in the Battle of Coleto on March 19–20, performing well, but the Texians were overrun and ultimately forced to surrender

[EX Q]: Question: Who did Wendi Richter beat to become AWA Women's Champion? Passage 1:The team's first feud was against The Midnight Rockers, whom they defeated for the AWA World Tag Team Championship on March 19, 1988. During their year long title reign, Badd Company would feud heavily with Chavo and Mando Guerrero and the team known as the Top Guns (Ricky Rice and Derrick Dukes). They teamed with Madusa Miceli to face the team of the Top Guns and Wendi Richter at the first AWA PPV, SuperClash III. Both Badd Company's Tag Team Title and Wendi Richter's AWA World Women's Championship were on the line, but since Richter pinned Miceli, Badd Company remained the champions. Diamond and Tanaka's reign ended on March 25, 1989 as they lost to "the Olympians" (Brad Rheingans and Ken Patera). Shortly after losing their titles they split from Page, and had a short feud against each other before wrestling in singles competition until early 1990. Just before moving to the WWF, Diamond teamed with The Trooper Del Wilkes for a short run at the AWA Tag Team Titles against The Destruction Crew (Mike Enos and Wayne Bloom). Diamond and Trooper actually defeated The Destruction Crew, but were not awarded the titles when it was determined that Diamond pinned the wrong person.
 Passage 2:Early in the Global War on Terror, Fontes served at US Central Command J5 overseeing issues of political-military cooperation in Afghanistan. In June 2004, she was moved to Combined Forces Command - Afghanistan headquarters in Kabul and served under David Barno as the head of the CJ5 staff for political-military coordination. Her staff was responsible for keeping General Barno "on message", overseeing the policies impacting military operations, and performing liaison work with both the Afghan Ministry of Defense and United Nations Assistance Mission in Afghanistan. At the end of her first year in Afghanistan and following Karl Eikenberry's assumption of command from Barno, Fontes volunteered to lead the Provincial Reconstruction Team (PRT) in Tarinkot. Daniel Green, the political adviser for the PRT, reported that though some Soldiers at the PRT had initial concerns due to her gender, those worries were shortly put to rest. She had been active in engaging with the Afghan people. Green said that Fontes, then a Lieutenant Colonel, pitched in a few hundred dollars of her own money to host a lunch on the PRT for local Afghan leaders. An article in Vanity Fair relates a story that she once refused to depart a meeting with Afghan elders in Chora District under threat of small arms fire, for fear of appearing weak in the face of the Taliban. Green asserts that in early 2006, she survived the first suicide vehicle-borne improvised explosive device attack in Urozgan Province due in part to the device's failure to detonate all of the mortar shells of which it was comprised. She departed Afghanistan in May 2006 to attend the US War College, graduating in 2007. She had been promoted that year to colonel. She was subsequently assigned as the chief of the American Security Assistance Office in Pakistan.
 Passage 3:Alydeed was owned and raced by David Willmot's Kinghaven Farms. Racing from a base at Woodbine Racetrack in Toronto, at age two his best performances were wins in an allowance race at Gulfstream Park in Florida, where he equalled the track record for 6.5 furlongs, and a win in Woodbine's Victoria Stakes. At age three, Alydeed won five of his ten starts. Near the end of April 1992, he was sent to Churchill Downs in Louisville, Kentucky where he won the Derby Trial. Based on his strong performance, his handlers decided to run him in the second leg of the U.S. Triple Crown series, the Preakness Stakes where he ran second to Pine Bluff. Back at Woodbine Racetrack, he won the Plate Trial Stakes then ran away from the field in the final quarter of a mile to win Canada's most prestigious race, the Queen's Plate. In the second leg of the Canadian Triple Crown series, the Prince of Wales Stakes, Alydeed was sent off as the prohibitive favorite at 1/9 odds. However, on a muddy Fort Erie Racetrack, Alydeed ran second to Benburb. Alydeed then elected to skip the third jewel of the Canadian Triple Crown opting for the Grade 1 Travers Stakes at Saratoga Race Course where he finished eighth to Thunder Rumble as the 8-5 favourite.
