[EX Q]: Question: Who designed Hans Klemm's first light aircraft? Passage 1:The head of the femur, which articulates with the acetabulum of the pelvic bone, comprises two-thirds of a sphere. It has a small groove, or fovea, connected through the round ligament to the sides of the acetabular notch. The head of the femur is connected to the shaft through the neck or collum. The neck is 45cm. long and the diameter is smallest front to back and compressed at its middle. The collum forms an angle with the shaft in about 130 degrees. This angle is highly variant. In the infant it is about 150 degrees and in old age reduced to 120 degrees on average. An abnormal increase in the angle is known as coxa valga and an abnormal reduction is called coxa vara. Both the head and neck of the femur is vastly embedded in the hip musculature and can not be directly palpated. In skinny people with the thigh laterally rotated, the head of the femur can be felt deep as a resistance profound (deep) for the femoral artery.
Passage 2:Born in Tel Aviv, Israel, on November 26, 1971, Huberman is the son of Holocaust survivors. He and his family moved to Oak Ridge, Tenn., when his father, a cancer researcher, began working at the Oak Ridge National Laboratory. Huberman attended the University of WisconsinMadison, graduating with a Bachelor's Degree in psychology and English in 1994. After graduation, he joined the Chicago Police Department where he initially served as a beat officer. While working full-time as a Chicago police officer, Huberman attended night classes at the University of Chicago and earned two advanced degrees in 2000, a Master of Social Work from the School of Social Service Administration and a Master of Business Administration from the university's Graduate School of Business (now the Booth School of Business). Huberman was a recipient of The Paul & Daisy Soros Fellowships for New Americans and an Albert Schweitzer Fellow while attending the University of Chicago.
Passage 3:Hans Klemm's first light aircraft was the Daimler L15 and the L20 had much in common with it. Both were cantilever monoplanes with twin open, tandem cockpits and engines of very low power. The L20's low wing distinguished it from its predecessor and had the advantage of providing a low centre of gravity and better view during the landing approach as well as better protection for occupants in case of crash landings. The low-set wing also allowed a shorter undercarriage on the L20, which was otherwise like that of the L15 with the wheels independently mounted on pairs of centrally hinged V-struts and with vertical shock absorbing legs to the wing underside. Wheels were sometimes replaced by floats. Intended from the start for serial production, the L20's structure was simplified, with a pentagonal cross-section fuselage lacking the L15's rounded upper and lower surfaces. The fuselage was wooden framed with canvas covering. The overall strength of the structure, which had a safety factor of 12, was emphasised.

[EX Q]: Question: What shape or object is the type of bell opening of the tower named after? Passage 1:Robert Riabhach ("Grizzled") Duncanson, 4th Chief of Clann Dhonnchaidh, was a strong supporter of King James I (14061437) and was incensed by his murder at the Blackfriars Dominican Friary in Perth. He tracked down and captured two of the regicides, Sir Robert Graham and the King's uncle Walter Stewart, Earl of Atholl, as they hid above Invervack in Atholl, and turned them over to the Crown. They were tortured to death in the Grassmarket in Edinburgh on the orders of the Regent, James I's widow, Joan Beaufort (d. 1445). The Collins Scottish Clan & Family Encyclopedia states that they were put to death with considerable savagery. The Robertson crest badge of a right hand upholding an imperial crown was awarded by James II (143760) to the 4th chief on 15 August 1451 as a reward for capturing his father's assassins. The highly unusual third supporter (below the shield) on the Robertson coat of arms, of a "savage man in chains" is in reference to the capture of Graham. It is in honour of Robert Riabhach that his descendants took the name Robertson. James II also erected the clan lands into the Barony of Struan, which formerly took in extensive lands in Highland Perthshire, notably in Glen Errochty, the north and south banks of Loch Tay and the area surrounding Loch Rannoch. None of these lands are any longer in the possession of the clan.
Passage 2:The church is constructed in punch-dressed sandstone ashlar, and has slate roofs with inserted skylight windows. Its architectural style is Early English. The plan consists of a four-bay nave without aisles, a two-bay chancel with a north chapel and a south vestry, and a west tower. The tower is in three stages, with clasping buttresses, and contains paired west doorways, a clock face in a diamond-shaped surround, and pairs of louvred bell openings. At the top of the tower is an embattled parapet with octagonal corner pinnacles, and there are more pinnacles at the angles of the nave. The bays of the nave are separated by buttresses, and each bay contains a corbel-table and a pair of lancet windows. The sides of the chancel also contain paired lancet windows, and the east window consists of a triple stepped lancet in a blank arch. The north chapel is gabled, and contains a wheel window. The interior has been remodelled, but originally it contained a three-sided gallery on cast iron columns.
Passage 3:The rest of the matches for the show were announced on September 25, the day after Destruction in Kobe. Added were title matches for both of NJPW's junior heavyweight titles. In the IWGP Junior Heavyweight Championship match, Kushida would defend the title against Will Ospreay. After successfully defending the title against El Desperado on September 16 at Destruction in Hiroshima, Kushida was approached by Ospreay, who stated that he was being defined as the man who could not beat Kushida and wanting to change that perception, challenged him to a title match. This was followed by Hiromu Takahashi entering the ring, but before he could make his own challenge, he was knocked out by Ospreay. Ospreay had been defeated by Kushida in all four of their previous matches against each other, including the finals of the 2017 Best of the Super Juniors and What Culture Pro Wrestling's 2017 Pro Wrestling World Cup tournaments, as well as two IWGP Junior Heavyweight Championship matches, which took place on April 10, 2016, at Invasion Attack 2016 and June 19, 2016, at Dominion 6.19 in Osaka-jo Hall. In the IWGP Junior Heavyweight Tag Team Championship match, Funky Future (Ricochet and Ryusuke Taguchi) were set to defend the title against the mystery team known only as "Roppongi 3K". After dissolving his Roppongi Vice tag team with Beretta on September 16, Rocky Romero approached Ricochet and Taguchi after they had successfully defended the IWGP Junior Heavyweight Tag Team Championship against Taichi and Yoshinobu Kanemaru and announced he was bringing in a new team to challenge them for the title. Heading into the title match, the identities of Roppongi 3K were kept secret.

[EX Q]: Question: How much was Alford purchased for? Passage 1:Their third album, Panorama, was released in 1980. Although it peaked at number 5 on the Billboard 200 and has been certified Platinum, it was less commercially successful than its predecessors. A single, "Touch and Go", peaked at number 37 on the Billboard Hot 100. Their next album, Shake It Up (1981), fared better commercially, going platinum by the end of the year and spawning their first Top 10 single with its title track. 1984's Heartbeat City was the band's most successful, hitting number 3 on the Billboard 200. Its lead single, "You Might Think", reached number 7 in the US, with three more singles: "Magic", "Drive", and "Hello Again" reaching number 12, 3, and 20, respectively on the Billboard Hot 100. Their Greatest Hits album, released later that year, contained the singles "Tonight She Comes" and a remixed version of "I'm Not the One", and has gone 6x platinum. Their final album before their breakup, Door to Door (1987), spawned the single "You Are the Girl" which reached number 17 on the Hot 100; it was their last Top 40 hit as a band.
Passage 2:Born in Bucharest on December 28 or 29, 1840, his father was Lazar (Lazaros) Kalenderoglu (or Calenderoglu). Of possible Smyrniote origin, the family functioned as one of the largest banking and exporting institutions in Wallachia, and then in the United Principalities. Lazar had risen into the ranks of Wallachia's boyar nobility: joining the Bucharest local government in 1838, 1844, and 1847, he was awarded the title of pitar, advancing to paharnic in the 1850s. His son would later falsely claim that the Kalenderoglus played a part in the Wallachian Revolution of 1848, although Lazar is known to have held relevant positions in the National Party in 1857, briefly serving as its chairman alongside Constantin A. Cretulescu. The last-ever tenant and tax collector of Predeal customs, Kalenderoglu had his estate in Olt County, outside Colonesti, reduced during the land reform of 1864. Another of his estates, at Balcesti, was repurchased by the Balcescu boyars. However, he still left Ioan the manor of Schitu-Greci.
Passage 3:Timothy Woodbridge (February 27, 1709 May 10, 1774) was an American missionary, deacon and schoolteacher, later a judge, representative, and Superintendent of Indian Affairs, from Springfield, Massachusetts, who spent most of his adult life in Stockbridge, Massachusetts, teaching the Mahicans and other Native Americans to read and write, English customs and the Christian religion. About him, Jonathan Edwards said, "By his long-proved justice and integrity, he has gained a vast esteem with the Indians". Reverend John Sergeant described his efforts in this way: "Mr. Woodbridge ... has a very numerous school and a tedious task of it; lives a very lonesome life; is indeed indefatigable in his business; and no body deserves more of the publick than he." Gideon Hawley called him "a man of abilities... always poor, and had a powerful party against him; but he rose to be the first man in the county." Timothy worked very closely with all three men. He was instrumental in the purchase of large tracts of land in western New England from the Native Americans, such as modern-day Lenox and Alford, Massachusetts, by parlaying this reputation and experience.
