PROBLEM: Passage: Monteverdi was an established court composer in the service of Duke Vincenzo Gonzaga in Mantua when he wrote his first operas, L'Orfeo and L'Arianna, in the years 160608. After falling out with Vincenzo's successor, Duke Francesco Gonzaga, Monteverdi moved to Venice in 1613 and became director of music at St Mark's Basilica, a position he held for the rest of his life. Alongside his steady output of madrigals and church music, Monteverdi continued to compose works for the stage, though not actual operas. He wrote several ballets and, for the Venice carnival of 162425, Il combattimento di Tancredi e Clorinda ("The Battle of Tancred and Clorinda"), a hybrid work with some characteristics of ballet, opera and oratorio.
In 1637 fully-fledged opera came to Venice with the opening of the Teatro San Cassiano. Sponsored by the wealthy Tron family, this theatre was the first in the world specifically devoted to opera. The theatre's inaugural performance, on 6 March 1637, was L'Andromeda by Francesco Manelli and Benedetto Ferrari. This work was received with great enthusiasm, as was the same pair's La Maga fulminata the following year. In rapid succession three more opera houses opened in the city, as the ruling families of the Republic sought to express their wealth and status by investing in the new musical fashion. At first, Monteverdi remained aloof from these activities, perhaps on account of his age (he was over 70), or perhaps through the dignity of his office as maestro di capella at St. Mark's. Nevertheless, an unidentified contemporary, commenting on Monteverdi's silence, opined that the maestro might yet produce an opera for Venice: "God willing, one of these nights he too will step onto the stage." This remark proved prescient; Monteverdi's first public contribution to Venetian opera came in the 163940 carnival season, a revival of his L'Arianna at the Teatro San Moise.L'Arianna was followed in rapid succession by three brand new Monteverdi operas, of which Il ritorno was the first. The second, Le nozze d' Enea in Lavinia ("The Marriage of Aeneas to Lavinia"), was performed during the 164041 carnival; Monteverdi's music is lost, but a copy of the libretto, of unknown authorship, survives. The last of the three, written for the 164243 carnival, was L'incoronazione di Poppea ("The Coronation of Poppea"), performed shortly before the composer's death in 1643.
Question: Where did Monteverdi perform his first opera?

SOLUTION: Teatro San Moise.

PROBLEM: Passage: After two more EPs on Kompakt, the Orb (now composed of only Paterson and Fehlmann) released Okie Dokie It's The Orb on Kompakt, which featured new material in addition to tweaked versions of their previous Kompakt output. By this stage, Allmusic observed, Thomas Fehlmann had become the primary creative figure in the Orb, "inhibiting Alex Paterson's whimsical impulses". Because of this, Okie Dokie was considerably more focused and less "goofy" than Cydonia and Bicycles & Tricycles. Fehlmann's trademark hypnotic loops and delays made him the centre of Okie Dokie production and, according to Pitchfork Media, made it "difficult to say where [Paterson] is in the picture". The Orb's releases with Kompakt gained them back much of their musical credibility with the press and showed that they could "age gracefully".In August 2006, the founders of the Orb - Paterson and Cauty - released Living in a Giant Candle Winking at God, their debut album as the Transit Kings with Guy Pratt and Pratt's associate, Dom Beken. The album featured appearances from Smiths' guitarist Johnny Marr and comedian Simon Day. Beken described Living in a Giant Candle Winking at God as "self-consciously musically written and less sample-based" compared to the members' previous work. Living had been in production since 2001, but due to members' other obligations, it was delayed for several years. The album received mixed critical reactions, with reviewers such as The Sun comparing the album favourably to the music of DJ Shadow and Royksopp while other publications, such as The Times, called it "Orb-lite" and proclaimed it to be "Deep Forest-style sludge". Soon after the album's release, Cauty left the Transit Kings on "extended leave", leaving the project in indefinite limbo. Paterson and Beken reunited in 2008 as High Frequency Bandwidth, an ambient hip hop group on the Malicious Damage label.
Question: What is the first name of the person who it was said was difficult to say where he was in the picture?

SOLUTION: Alex.

PROBLEM: Passage: The Chinnerys were wealthy and influential. William Chinnery's father, also named William, owned trading ships and named one Gilwell in 1800. William and Margaret Chinnery initially resided in London, and after three years of marriage and inheriting Gilwell in 1792, they moved to Gilwell in 1793. They soon shocked the populace by renaming Osborne Hall to "Gilwell Hall". William Chinnery expanded Gilwell's land holdings through significant purchases over 15 years and, with his wife, transformed it into a country estate with gardens, paths, and statues. Parts of the garden, paths, and dwelling modifications exist into the 21st century. William Chinnery was exposed as the embezzler of a small fortune from the British Treasury where he worked and was dismissed from all his posts on 12 March 1812. Margaret Chinnery was forced to sign over Gilwell Estate to the Exchequer on 2 July 1812.The Chinnery family was prominent enough that members of the English nobility visited often during the 1790s and early 19th century. King George III visited on occasion, and the Prince Regent, who later became George IV, was a regular visitor. George III's seventh son, Prince Adolphus, became a family friend, lived at Gilwell for a while, and tutored their eldest son George.Gilpin Gorst bought the estate in 1815 at public auction, and his son sold it to Thomas Usborne in 1824. When London Bridge was replaced in 1826, Usborne bought pieces of the stone balustrades, which date to 1209, and erected them behind the White House around the Buffalo Lawn. The estate changed ownership more times, but these families did not maintain the property and it fell into disrepair by 1900. Reverend Cranshaw, a local resident, bought the estate in 1911 and was the last owner prior to the Boy Scout Association, as it was then known.
Question: What did Thomas Usborne erect behind the White House around the Buffalo Lawn?

SOLUTION:
stone balustrades.
