[Q]: Passage: In Osbert: A Portrait of Osbert Lancaster, Boston comments that after the dramatic events in Athens his subject's later life was uneventful and industrious with "a somewhat dismaying dearth of rows, intrigues, scandals or scrapes to report." The Lancasters had a Georgian house in Henley-on-Thames, and a flat in Chelsea, where they lived from Mondays to Fridays. He worked at home in the mornings, on illustrations, stage designs, book reviews and any other commissions, before joining his wife for a midday dry martini and finally dressing and going to one of his clubs for lunch. After that he would walk to the Express building in  Fleet Street at about four in the afternoon. There he would gossip with his colleagues before sitting at his desk smoking furiously, producing the next day's pocket cartoon. By about half-past six he would have presented the cartoon to the editor and be ready for a drink at El Vino's across the road, and then the evening's social events.Karen Lancaster died in 1964. They were markedly different in character, she quiet and home-loving, he extrovert and gregarious, but they were devoted to each other, and her death left him devastated. Three years later he married the journalist Anne Scott-James; they had known each other for many years, although at first she did not much like him, finding him "stagey" and "supercilious". By the 1960s they had become good friends, and after Karen died the widowed Lancaster and the divorced Scott-James spent increasing amounts of time together. Their wedding was at the Chelsea Register Office on 2 January 1967. After their marriage they kept his Chelsea flat,  and lived at weekends in her house in the Berkshire village of Aldworth, the house in Henley having been sold. 
Question: What are the full names of the two people whose wedding was at the Chelsea Register Office on 2 January 1967?
[A]: Osbert Lancaster.


[Q]: Passage: Ottavio's marriage troubled Alessandro; he struggled with the burden of chastity and entertained fantasies of marrying a princess. He resented his younger brother's arrangement; during the wedding ceremony he "became more deathly pale than death itself, and, so they say, is unable to bear this thing, that he, the first-born, should see himself deprived of such splendid status and of the daughter of an Emperor." In 1546 Paul gave Pier Luigi the duchies of Parma and Piacenza as papal fiefs, a highly political move by the pope: in doing so he gave titles and wealth to Pier and appointed a lord who was subservient and owed a debt of gratitude, guaranteeing that the duchies would remain under papal control. At the same time, Ottavio was posted to the North of Italy to support Charles. By 1546 Ottavio was 22 years old, married to Margaret of Austria and an accomplished and distinguished individual. In 1547 his father was assassinated and Ottavio claimed the dukedom of Parma and Piacenza against the express wishes of both Charles, his father-in-law, and Paul. In doing so, Ottavio acted in opposition to the pope's desire to maintain the duchies as papal fiefs, and to Charles, whom he believed responsible for the plot to assassinate Pier Luigi.Titian was a personal friend of Charles; the commissioning of the portrait was most likely intended by Paul as a signal of allegiance to the emperor. Pressure from reforming monarchs in France and Spain, coupled with a general shift of influence in France's favour, ended the Farnese hold on the papacy soon after Paul's death. Ottavio excelled as a military commander and was awarded the Golden Fleece by the emperor. While the post had been given as a means to strengthen the family position, it did not come without cost. His success bred resentment amongst his family, as he began to see himself unaccountable to Rome.At the time of the portrait Paul had convinced Alessandro to retain the post, hinting that he would later succeed him as pope – an aspiration that was ultimately frustrated. As Alessandro realised the emptiness of the promise he lost confidence in both his grandfather's word and political credibility. 
Question: What was the name of Alessandro's brother?
[A]: Ottavio.


[Q]: Passage: During the 1980s, there was increasing pressure on both the Polish and Soviet governments to release documents related to the massacre. Polish academics tried to include Katyn in the agenda of the 1987 joint Polish-Soviet commission to investigate censored episodes of the Polish-Russian history. In 1989, Soviet scholars revealed Joseph Stalin had indeed ordered the massacre, and in 1990 Mikhail Gorbachev admitted the NKVD had executed the Poles and confirmed two other burial sites similar to the site at Katyn: Mednoye and Piatykhatky.
On 30 October 1989, Gorbachev allowed a delegation of several hundred Poles, organized by the Polish association Families of Katyń Victims, to visit the Katyn memorial. This group included former U.S. national security advisor Zbigniew Brzezinski. A mass was held and banners hailing the Solidarity movement were laid. One mourner affixed a sign reading "NKVD" on the memorial, covering the word "Nazis" in the inscription such that it read "In memory of Polish officers killed by the NKVD in 1941." Several visitors scaled the fence of a nearby KGB compound and left burning candles on the grounds. Brzezinski commented:
It isn't a personal pain which has brought me here, as is the case in the majority of these people, but rather recognition of the symbolic nature of Katyń. Russians and Poles, tortured to death, lie here together. It seems very important to me that the truth should be spoken about what took place, for only with the truth can the new Soviet leadership distance itself from the crimes of Stalin and the NKVD. Only the truth can serve as the basis of true friendship between the Soviet and the Polish peoples. The truth will make a path for itself. I am convinced of this by the very fact that I was able to travel here.
Brzezinski further stated:
The fact that the Soviet government has enabled me to be here—and the Soviets know my views—is symbolic of the breach with Stalinism that perestroika represents.
His remarks were given extensive coverage on Soviet television. At the ceremony he placed a bouquet of red roses bearing a handwritten message penned in both Polish and English: "For the victims of Stalin and the NKVD. Zbigniew Brzezinski".On 13 April 1990, the forty-seventh anniversary of the discovery of the mass graves, the USSR formally expressed "profound regret" and admitted Soviet secret police responsibility. The day was declared a worldwide Katyn Memorial Day (Polish: Światowy Dzień Pamięci Ofiar Katynia). 
Question: What is the last name of the person for whom the very fact that that the Soviet government enabled him to be there is ostensibly symbolic of the breach with Stalinism that perestroika represents?
[A]:
Brzezinski.
