TASK DEFINITION: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
PROBLEM: Passage: Bach is believed to have written Christ lag in Todes Banden in 1707. He was a professional organist aged 22, employed from 1703 in Arnstadt as the organist of the New Church (which replaced the burned Bonifatiuskirche, today known as the Bach Church). At age 18, he had inspected the new organ built by Johann Friedrich Wender, was invited to play one Sunday, and was hired. The organ was built on the third tier of a theatre-like church. Bach's duties as a church musician involved some responsibility for choral music, but the exact year he began composing cantatas is unknown. Christ lag in Todes Banden is one of a small group of cantatas that survive from his early years. According to the musicologist Martin Geck, many details of the score reflect "organistic practice".In Arnstadt, the Kantor (church musician) Heindorff was responsible for church music in the Upper Church (Liebfrauenkirche), and the New Church where Bach was the organist. He typically conducted music in the Upper Church and would appoint a choir prefect for vocal music in the New Church. Wolff notes that "subjecting his works to the questionable leadership of a prefect" was not what Bach would have done. Therefore, most cantatas of the period are not for Sunday occasions, but restricted to special occasions such as weddings and funerals. Christ lag in Todes Banden is the only exception, but was most likely composed not for Arnstadt but for an application to a more important post at the Divi Blasii church in Mühlhausen.

SOLUTION: What was the name of the Bach Church when Bach was the organist?

PROBLEM: Passage: The Rosetta Stone is listed as "a stone of black granodiorite, bearing three inscriptions ... found at Rosetta" in a contemporary catalogue of the artefacts discovered by the French expedition and surrendered to British troops in 1801. At some period after its arrival in London, the inscriptions on the stone were coloured in white chalk to make them more legible, and the remaining surface was covered with a layer of carnauba wax designed to protect the Rosetta Stone from visitors' fingers. This gave a dark colour to the stone that led to its mistaken identification as black basalt. These additions were removed when the stone was cleaned in 1999, revealing the original dark grey tint of the rock, the sparkle of its crystalline structure, and a pink vein running across the top left corner. Comparisons with the Klemm collection of Egyptian rock samples showed a close resemblance to rock from a small granodiorite quarry at Gebel Tingar on the west bank of the Nile, west of Elephantine in the region of Aswan; the pink vein is typical of granodiorite from this region.The Rosetta Stone is 1,123 millimetres (3 ft 8 in) high at its highest point, 757 mm (2 ft 5.8 in) wide, and 284 mm (11 in) thick. It weighs approximately 760 kilograms (1,680 lb). It bears three inscriptions: the top register in Ancient Egyptian hieroglyphs, the second in the Egyptian Demotic script, and the third in Ancient Greek. The front surface is polished and the inscriptions lightly incised on it; the sides of the stone are smoothed, but the back is only roughly worked, presumably because this would have not been visible when it was erected.

SOLUTION: How many kilograms does the Rosetta Stone weigh?

PROBLEM: Passage: In late 2008, Fortress Investments threatened to foreclose on Neverland Ranch, which Jackson had used as collateral for loans running into tens of millions of dollars. Fortress sold Jackson's debts to Colony Capital LLC. In November, Jackson transferred Neverland Ranch's title to Sycamore Valley Ranch Company LLC, a joint venture between Jackson and Colony Capital LLC. The deal earned him $35 million. Jackson arranged to sell a large collection of memorabilia through Julien's Auction House. The auction was scheduled to take place between April 22 and 25, 2009. An exhibition of the lots opened, but Jackson canceled the auction.In March 2009, at a press conference at London's O2 Arena, Jackson announced a series of comeback concerts titled This Is It, against a background of speculation about his finances and his health. The shows were to be his first major tour since the HIStory World Tour finished in 1997. Jackson suggested he would retire after the shows. The initial plan was for 10 concerts in London, followed by shows in Paris, New York City and Mumbai. Randy Phillips, president and chief executive of AEG Live, predicted that the first 10 dates would earn Jackson £50 million. The London residency was increased to 50 dates after record-breaking ticket sales: over one million were sold in less than two hours. The concerts were to run from July 13, 2009 to March 6, 2010. Jackson rehearsed in Los Angeles in the weeks leading up to the tour under the direction of choreographer Kenny Ortega. Most rehearsals took place at the Staples Center, owned by AEG.

SOLUTION:
What location did an exhibition of lots open containing Jackson's memorabilia?
