[Q]: Passage: ABKCO Industries was formed in 1968 by Allen Klein as an umbrella company to ABKCO Records. Klein hired May Pang as a receptionist in 1969. Through involvement in a project with ABKCO, Lennon and Ono met her the following year. She became their personal assistant. In 1973, after she had been working with the couple for three years, Ono confided that she and Lennon were becoming estranged. She went on to suggest that Pang should begin a physical relationship with Lennon, telling her, "He likes you a lot." Astounded by Ono's proposition, Pang nevertheless agreed to become Lennon's companion. The pair soon left for Los Angeles, beginning an 18-month period he later called his "lost weekend". In Los Angeles, Pang encouraged Lennon to develop regular contact with Julian, whom he had not seen for two years. He also rekindled friendships with Starr, McCartney, Beatles roadie Mal Evans, and Harry Nilsson. While Lennon was drinking with Nilsson, he misunderstood something that Pang had said and attempted to strangle her. Lennon relented only after he was physically restrained by Nilsson.In June, Lennon and Pang returned to Manhattan in their newly rented penthouse apartment where they prepared a spare room for Julian when he visited them.  Lennon, who had been inhibited by Ono in this regard, began to reestablish contact with other relatives and friends.  By December, he and Pang were considering a house purchase, and he refused to accept Ono's telephone calls. In January 1975, he agreed to meet Ono, who claimed to have found a cure for smoking. After the meeting, he failed to return home or call Pang. When Pang telephoned the next day, Ono told her that Lennon was unavailable because he was exhausted after a hypnotherapy session. Two days later, Lennon reappeared at a joint dental appointment; he was stupefied and confused to such an extent that Pang believed he had been brainwashed. Lennon told Pang that his separation from Ono was now over, although Ono would allow him to continue seeing her as his mistress. 
Question: What is the name of the person who Pang believed had been brainwashed due to the extent of his stupefaction and confusion?
[A]: Lennon.


[Q]: Passage: The panel has at various times been attributed to van der Goes and van Eyck, but was recognized as by Memling as early as the time of the seminal 1902 exhibition Exposition des primitifs flamands à Bruges in Bruges, when it was lent by Léopold Goldschmidt of Paris. In 1916 Max J. Friedländer described it as "without doubt" by Memling, and c. 1475. The art historian Catheline Périer-d'Ieteren, while noting that Memling's portrait faces were rarely underdrawn, wrote that this panel contains "thin yet confident incised lines" which may be preliminary drawings for Maria's face, perhaps made from life.
The triptych was recorded in an inventory of Tommaso's holdings upon his death. The New York panels passed through Tommaso's son Francesco. The central panel was described in his 1544 will as "a small tabernacle with three movable wings, in which is depicted the glorious Virgin Mary and the father and mother of the donor" (unum tabernaculettum que clauditur con tribus sportellis, in qua est depicta imago Gloriossime virginis Marie et patris et matris dicti testatoris). Francesco bequeathed the triptych to the convent of the hospital of Santa Maria Nuova in Florence. Records indicate a small intact winged altarpiece which stayed in the hospital's possession until around the time of the Napoleonic occupation, when it was probably broken up.Maria's panel was sold as a Dieric Bouts for 6,000 francs in 1870. It later passed through several private collections before arriving in the possession of Elia Volpi of Rome, who briefly returned it to Florence. Thereafter the panels were in London from 1901, from where they were sold to Villeroy Goldschmidt of Paris by for $426,500 in 1910. They were purchased, also in 1910, by the collector Benjamin Altman of New York on the advice of Max Friedländer, along with works by Albrecht Dürer, Gerard David and Hans Holbein the Younger – paintings whose "grave austerity seems to have been most in tune with his own taste". Altman bequeathed his holdings to the Metropolitan on his death in 1913. 
Question: What was probably broken up around the time of the Napoleonic occupation?
[A]: winged altarpiece.


[Q]: Passage: Tchaikovsky remained abroad for a year after the disintegration of his marriage. During this time, he completed Eugene Onegin, orchestrated his Fourth Symphony, and composed the Violin Concerto. He returned briefly to the Moscow Conservatory in the autumn of 1879. For the next few years, assured of a regular income from von Meck, he traveled incessantly throughout Europe and rural Russia, mainly alone, and avoided social contact whenever possible. During this time, Tchaikovsky's foreign reputation grew and a positive reassessment of his music also took place in Russia, thanks in part to Russian novelist Fyodor Dostoyevsky's call for "universal unity" with the West at the unveiling of the Pushkin Monument in Moscow in 1880. Before Dostoyevsky's speech, Tchaikovsky's music had been considered "overly dependent on the West". As Dostoyevsky's message spread throughout Russia, this stigma toward Tchaikovsky's music evaporated. An unprecedented acclaim for him even drew a cult following among the young intelligentsia of Saint Petersburg, including Alexandre Benois, Léon Bakst and Sergei Diaghilev.Two musical works from this period stand out. With the Cathedral of Christ the Saviour nearing completion in Moscow in 1880, the 25th anniversary of the coronation of Alexander II in 1881, and the 1882 Moscow Arts and Industry Exhibition in the planning stage, Nikolai Rubinstein suggested that Tchaikovsky compose a grand commemorative piece. Tchaikovsky agreed and finished it within six weeks. He wrote to Nadezhda von Meck that this piece, the 1812 Overture, would be "very loud and noisy, but I wrote it with no warm feeling of love, and therefore there will probably be no artistic merits in it". He also warned conductor Eduard Nápravník that "I shan't be at all surprised and offended if you find that it is in a style unsuitable for symphony concerts". Nevertheless, the overture became, for many, "the piece by Tchaikovsky they know best"., particularly well-known for the use of cannon in the scores.On 23 March 1881, Nikolai Rubinstein died in Paris. That December, Tchaikovsky started work on his Piano Trio in A minor, "dedicated to the memory of a great artist". First performed privately at the Moscow Conservatory on the first anniversary of Rubinstein's death, the piece became extremely popular during the composer's lifetime; in November 1893, it would become Tchaikovsky's own elegy at memorial concerts in Moscow and St. Petersburg. 
Question: What is the full name of the great artist to whose memory Tchaikovsky dedicated his Piano Trio in A minor?
[A]:
Nikolai Rubinstein.
