PROBLEM: Passage: It is not clear why, in 1873, Alkan decided to emerge from his self-imposed obscurity to give a series of six Petits Concerts at the Érard piano showrooms. It may have been associated with the developing career of Delaborde, who, returning to Paris in 1867, soon became a concert fixture, including in his recitals many works by his father, and who was at the end of 1872 given the appointment that had escaped Alkan himself, Professor at the Conservatoire. The success of the Petits Concerts led to them becoming an annual event (with occasional interruptions caused by Alkan's health) until 1880 or possibly beyond. The Petits Concerts featured music not only by Alkan but of his favourite composers from Bach onwards, played on both the piano and the pédalier, and occasionally with the participation of another instrumentalist or singer. He was assisted in these concerts by his siblings, and by other musicians including Delaborde, Camille Saint-Saëns, and Auguste Franchomme.Those encountering Alkan at this phase included the young Vincent d'Indy, who recalled Alkan's "skinny, hooked fingers" playing Bach on an Érard pedal piano: "I listened, riveted to the spot by the expressive, crystal-clear playing." Alkan later played Beethoven's Op. 110 sonata, of which d'Indy said: "What happened to the great Beethovenian poem ... I couldn't begin to describe – above all in the Arioso and the Fugue, where the melody, penetrating the mystery of Death itself, climbs up to a blaze of light, affected me with an excess of enthusiasm such as I have never experienced since. This was not Liszt—perhaps less perfect, technically—but it had greater intimacy and was more humanly moving ..."The biographer of Chopin, Frederick Niecks, sought Alkan for his recollections in 1880 but was sternly denied access by Alkan's concierge – "To my ... enquiry when he could be found at home, the reply was a ... decisive 'Never'." However, a few days later he found Alkan at Érard's, and Niecks writes of their meeting that "his reception of me was not merely polite but most friendly.". 
Question: Whose reception of Niecks was reportedly not merely polite but most friendly?

SOLUTION: Alkan.

PROBLEM: Passage: After further work as a répétiteur at the opera in Budapest, and with his standing enhanced by his association with Toscanini, Solti was given his first chance to conduct, on 11 March 1938. The opera was The Marriage of Figaro. During that evening, news came of the German invasion of Austria. Many Hungarians feared that Hitler would next invade Hungary; he did not do so, but Horthy, to strengthen his partnership with the Nazis, instituted anti-semitic laws, mirroring the Nuremberg Laws, restricting Hungary's Jews from engaging in professions. Solti's family urged him to move away. He went first to London, where he made his Covent Garden debut, conducting the London Philharmonic for a Russian ballet season. The reviewer in The Times was not impressed with Solti's efforts, finding them "too violent, for he lashed at the orchestra and flogged the music so that he endangered the delicate, evocative atmosphere." At about this time Solti dropped the name "György" in favour of "Georg".After his appearances in London Solti went to Switzerland to seek out Toscanini, who was conducting in Lucerne. Solti hoped that Toscanini would help find him a post in the US. He was unable to do so, but Solti found work and security in Switzerland as vocal coach to the tenor Max Hirzel, who was learning the role of Tristan in Wagner's opera. Throughout the Second World War, Solti remained in Switzerland. He did not see his father again: Mor Stern died of diabetes in a Budapest hospital in 1943. Solti was reunited with his mother and sister after the war. In Switzerland he could not obtain a work permit as a conductor, but earned his living as a piano teacher. After he won the 1942 Geneva International Piano Competition he was permitted to give piano recitals, but was still not allowed to conduct. During his exile, he met Hedwig (Hedi) Oeschli, daughter of a lecturer at Zürich University. They married in 1946. In his memoirs he wrote of her, "She was very elegant and sophisticated. ... Hedi gave me a little grace and taught me good manners – although she never completely succeeded in this. She also helped me enormously in my career". 
Question: What disease killed the father of the man who debuted with Covent Garden in London?

SOLUTION: diabetes.

PROBLEM: Passage: During the rage of Hurricane Katrina, Detective Andy Devereaux discovers the body of his former partner in a close to underwater warehouse. Quickly forgetting about his discovery, he joins a newly transferred detective named Stan Johnson (Curtis "50 Cent" Jackson) trying to end a conflict involving looters. 
Post-Katrina, Andy and Stan are now partners. They work with corrupt detectives Pepe and Barney, who are caught up in the murder of an undercover narcotics agent. Investigating the escalating police corruption in New Orleans is FBI Agent Brown. Brown brings up his thoughts to Police Captain Friendly who insists he is doing his best to solve the problems in his department.
Meanwhile, police therapist Nina Ferraro tries to help the detectives with their struggles, with little avail. She is particularly interested in Andy, whose father, also a detective, was murdered in the line of duty. 
Things are complicated further with Agent Brown's investigation into Andy and his crew. Brown tells Andy that he has an informant who is leaking out the details, and Andy, disbelieving at first, begins to resign himself to the fact that one of his men is betraying him. 
After Captain Friendly is assassinated by a local gangster named Chamorro, Andy, Stan, Pepe, and Barney decide to take the law into their own hands and go after Chamorro. While interrogating Chamorro, they find out that Brown has been supplying the drug dealer with information about the police raids, to help his own investigation. In a violent shootout, Barney accidentally shoots and kills Pepe.
Andy and Stan escape, only to return to the warehouse where they met. There Andy realizes that Stan is the informant. After the two start arguing, Brown shows up and there is another shootout, ending in Brown's death. Andy comforts a sobbing Stan, then Andy kills his partner, as he possibly did with his previous one. 
Question: What is the last name of the person whose father was murdered in the line of duty?

SOLUTION:
Devereaux.
