[EX Q]: Question: How many companies have offices in the tallest building in Dubai? Passage 1:Dubai, the largest city in the United Arab Emirates, is home to many modern high-rises, 108 of which stand taller than . The tallest building in Dubai is the Burj Khalifa, which rises and contains 163 floors. The tower has stood as both the tallest building in the world and the tallest man-made structure of any kind in the world since its completion in January 2010. The second-tallest building in Dubai is the Marina 101, which also stands as the world's second tallest residential skyscraper. The skyscrapers of Dubai are, for the most part, clustered in three different locations. The land along E 11 Road was the first to develop, followed by the Dubai Marina neighborhood and the Business Bay district.
 Passage 2:Montenegro has no currency of its own. As a constituent republic of the Socialist Federal Republic of Yugoslavia following World War II, and later of the Federal Republic of Yugoslavia, the Yugoslav dinar was the official currency in Montenegro. In November 1999, the government of Montenegro unilaterally designated the Deutsche Mark as its co-official currency with the dinar, and on 1 January 2001 the dinar officially ceased to be a legal tender in Montenegro. When the euro was introduced and the Deutsche Mark yielded, Montenegro followed suit and began using the euro as well, with no objection from the European Central Bank (ECB). The European Commission and the ECB have since voiced their discontent over Montenegro's unilateral use of the euro on several occasions.” A statement attached to their Stabilisation and Association Agreement with the EU read: "unilateral introduction of the euro was not compatible with the Treaty." The EU insists on the strict adherence to convergence criteria (such as spending at least 2 years in the ERMII system) which are not negotiable before euro adoption, but have not intervened to stop the unilateral adoption of the euro by Montenegro in 2002.
 Passage 3:In the 18th century, England was famous for its woollen and worsted cloth. That industry, centred in the east and south in towns such as Norwich, jealously protected their product. Cotton processing was tiny: in 1701 only of cottonwool was imported into England, and by 1730 this had fallen to . This was due to commercial legislation to protect the woollen industry. Cheap calico prints, imported by the East India Company from Hindustān (India), had become popular. In 1700 an Act of Parliament passed to prevent the importation of dyed or printed calicoes from India, China or Persia. This caused demand to switch to imported grey cloth instead—calico that had not been finished—dyed or printed. These were printed with popular patterns in southern England. Also, Lancashire businessmen produced grey cloth with linen warp and cotton weft, known as fustian, which they sent to London for finishing. Cottonwool imports recovered though, and by 1720 were almost back to their 1701 levels. Again the woollen manufacturers, in true protectionist fashion, claimed that the imports were taking jobs away from workers in Coventry. The Woollen, etc., Manufactures Act 1720 was passed, enacting fines against anyone caught wearing printed or stained calico muslins. Neckcloths and fustians were exempted. The Lancashire manufacturers exploited this exemption; coloured cotton weft with linen warp were specifically permitted by the 1736 Manchester Act. There now was an artificial demand for woven cloth.

[EX Q]: Question: Which Armored Regiment was based in a larger town? Passage 1:In March 1945, the 1st Tank Division with its 5th Armored Regiment was reassigned to the Japanese home islands in preparation for the expected invasion by Allied forces. It gained the IJA 1st Armored Regiment from the 3rd Tank Division, and formed part of the IJA 36th Army under the Japanese Twelfth Area Army. The headquarters unit and IJA 1st Armored Regiment were based in Sano, Tochigi, with the IJA 5th Armored Regiment stationed at Ōtawara, Tochigi (and later relocated to Kazo, Saitama, and the IJA 1st Mechanized Infantry Regiment and the Division’s mechanized artillery stationed at Tochigi. Anticipating that Allied forces would land at Kujūkuri Beach, the 1st Tank Division was to hold a defensive line stretching from Mount Tsukuba to the Tama River, with forward units deployed to Choshi, Chiba. The surrender of Japan came before the landing, and the 1st Armored Division did not see any combat on Japanese soil.
 Passage 2:Fredell Lack was born in Tulsa, Oklahoma, the oldest of three children of Jewish Eastern European (Latvian) immigrants, Abram I. Lack and Sarah Stillman Lack (who was a sister of noted painter Ary Stillman). She began violin lessons at age six, studying with Tosca Berger. When Fredell was 10, she moved with her family to Houston, Texas. There she studied with Josephine Boudreaux, the concertmaster of the Houston Symphony. At age 11, she first soloed with orchestra, performing the Wieniawski Concerto No. 2 with the Tulsa Philharmonic. At 12, Lack was accepted into the New York City studio of the legendary violinist and pedagogue Louis Persinger, whose other students included such artists as Yehudi Menuhin, Isaac Stern, and Ruggiero Ricci. She moved to New York and completed her pre-college schooling at the Bentley School while continuing her violin lessons with Persinger. At 17, she made her professional solo debut, playing the Mendelssohn Violin Concerto with the St. Louis Symphony. Subsequently she received a full scholarship to the Juilliard School in New York. She continued studying violin with Persinger there and also was deeply influenced by her study of chamber music with Felix Salmond. She received the Diploma from Juilliard at age 21.
 Passage 3:When the song was first released as a single in 1994, no remixes were commissioned. Carey re-released the song commercially in Japan in 2000, with a new remix known as the So So Def remix. The remix contains new vocals and is played over a harder, more urban beat that contains a sample of Afrika Bambaataa & the Soulsonic Force's "Planet Rock;" it features guest vocals by Jermaine Dupri and Bow Wow. The remix appears on Carey's compilation album Greatest Hits (2001) as a bonus track. A video was created for the So So Def remix, but it does not feature Carey or the hip-hop musicians that perform in the song. Instead, the video is animated and based on a scene in the video from Carey's "Heartbreaker" (1999). It features cartoon cameo appearances by Carey, Jermaine Dupri, Bow Wow, Luis Miguel (Carey's boyfriend at the time), Carey's dog Jack, and Santa Claus. In 2009 and 2010, the song was included in a music video accompanying ESPN's (and their sister station, ABC) Christmas Day coverage of the NBA.

[EX Q]: Question: Where was the author of Britannia's Pastorals educated? Passage 1:Hurricane Dorian was the strongest hurricane to affect the Bahamas on record, causing catastrophic damage in the Abaco Islands and Grand Bahama in early September 2019. The fifth tropical cyclone, fourth named storm, second hurricane, and first major hurricane of the annual hurricane season, Dorian originated from a westward traveling tropical wave that was located over a thousand miles east of the Windward Islands on August 23. The disturbance rapidly organized and became a tropical depression and later a tropical storm, both on August 24. The newly formed Dorian struggled to intensify over the next few days due to a combination of dry air and vertical wind shear. The storm passed over Barbados and entered the Caribbean Sea on August 26 as it gradually strengthened. Dorian made landfall in St. Lucia on the next day, which caused serious disruption to the system's structure. Initially predicted to strike Hispaniola, Dorian's track gradually shifted to the east as the storm neared Greater Antilles. Due to land interaction and the dry air, Dorian's center reformed north of its previous location, causing the system's track to shift northward. The storm then turned towards the northwest as it traveled through a weakness in a ridge. A combination of the dry air and shear relaxing as well as the warm sea surface temperatures, allowed Dorian to become a Category 1 hurricane as it passed over St. Thomas on August 28. The storm developed an eye in satellite imagery soon after, but dry air still continued to disrupt the system. The commencement of an eyewall replacement cycle on August 29 temporarily impeded intensification, but Dorian completed the cycle the next morning and soon resumed strengthening.
 Passage 2:Originally a backing band for burlesque shows, in their early years DeVotchKa also toured with burlesque performer and model Dita Von Teese. Numerous nationwide tours in support of self-released records earned the band an underground following. Their song "How It Ends" introduced the band to a wider audience after being featured in the trailer for Everything Is Illuminated, in a Gears of War 2 trailer called "The Last Day", and in an episode of Everwood (Season 4). Their performance at the 2006 Bonnaroo music festival was considered a breakout event. In between tours, the band was picked by first time film directors Jonathan Dayton and Valerie Faris to score Little Miss Sunshine, a 2006 film that would go on to garner four Academy Award nominations. DeVotchKa, along with composer Mychael Danna, composed and performed the majority of the music for the film's soundtrack and were nominated for a 2006 Grammy Award for Best Compilation Soundtrack. The main song, "The Winner Is", was also used in a commercial by the French-based environment and energy company Suez and the Dutch pension fund PGGM.
 Passage 3:In English, ottava rima first appeared in Elizabethan translations of Tasso and Ariosto. The form also became popular for original works, such as Michael Drayton's The Barons' Wars, Thomas Heywood's Troia Britannica, or Aemilia Lanyer's Salve Deus Rex Judaeorum. William Browne's Britannia's Pastorals also contains passages in ottava rima. The first English poet to write mock-heroic ottava rima was John Hookham Frere, whose 1817-8 poem Prospectus and Specimen of an Intended National Work used the form to considerable effect. Lord Byron read Frere's work and saw the potential of the form. He quickly produced Beppo, his first poem to use the form. Shortly after this, Byron began working on his Don Juan (1819–1824), probably the best-known English poem in ottava rima. Byron also used the form for The Vision of Judgment (1822). Shelley translated the Homeric Hymns into English in ottava rima. In the 20th century, William Butler Yeats used the form in several of his best later poems, including "Sailing to Byzantium" and "Among School Children". So did Kenneth Koch for instance in his autobiographical poem "Seasons on Earth" of 1987. In America Emma Lazarus wrote the poem An Epistle that consists of thirty four ottava rimas. Earlier Richard Henry Wilde used the stanza in his long poem Hesperia.
