Input: Consider Input: Passage: Shackleton's first task, on arriving at the Stromness station, was to arrange for his three companions at Peggoty Camp to be picked up. A whaler was sent round the coast, with Worsley aboard to show the way, and by the evening of 21 May all six of the James Caird party were safe.It took four attempts before Shackleton was able to return to Elephant Island to rescue the party stranded there. He first left South Georgia a mere three days after he had arrived in Stromness, after securing the use of a large whaler, The Southern Sky, which was laid up in Husvik Harbour. Shackleton assembled a volunteer crew, which had it ready to sail by the morning of 22 May. As the vessel approached Elephant Island they saw that an impenetrable barrier of pack ice had formed, some 70 miles (110 km) from their destination. The Southern Sky was not built for ice breaking, and retreated to Port Stanley in the Falkland Islands.On reaching Port Stanley, Shackleton informed London by cable of his whereabouts, and requested that a suitable vessel be sent south for the rescue operation. He was informed by the Admiralty that nothing was available before October, which in his view was too late. Then, with the help of the British Minister in Montevideo, Shackleton obtained from the Uruguayan government the loan of a tough trawler, Instituto de Pesca No. 1, which started south on 10 June. Again the pack thwarted them. In search of another ship, Shackleton, Worsley and Crean travelled to Punta Arenas, where they met Allan MacDonald, the British owner of the schooner Emma. McDonald equipped this vessel for a further rescue attempt, which left on 12 July, but with the same negative resultthe pack defeated them yet again. Shackleton later named a glacier after McDonald on the Brunt Ice Shelf in the Weddell Sea. After problems arose in identifying this glacier, a nearby ice rise was renamed the McDonald Ice Rumples.By now it was mid-August, more than three months since Shackleton had left Elephant Island. Shackleton begged the Chilean Government to lend him Yelcho, a small steam tug that had assisted Emma during the previous attempt. They agreed; on 25 August, Yelchocaptained by Luis Pardoset out for Elephant Island. This time, as Shackleton records, providence favoured them. The seas were open, and the ship was able to approach close to the island, in thick fog. At 11:40 a.m. on 30 August, the fog lifted, the camp was spotted and, within an hour, all the Elephant Island party were safely aboard, bound for Punta Arenas.
Question: What vessel did MacDonald equip for a further rescue attempt?

Output: Emma.

Input: Consider Input: Passage: After further work as a repetiteur 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 "Gyorgy" 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 Zurich 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?

Output: diabetes.

Input: Consider Input: Passage: After coming back from a mission in a private school in Oxfordshire with Shakeel, James is dumped by his girlfriend, Kerry Chang. As he leaves Kerry's room, he sees a red-shirt CHERUB called Andy Lagan and takes his temper out on him, beating him up. For this, James finds his friends ignoring him, and is punished with no holiday, suspension from missions, cleaning the mission preparation rooms every night for three months, and having anger management sessions with a counselor.
Zara feels sorry for James, so she gets him a low-risk mission to get him out of the punishment and so he can spend some time away from his friends blanking him. For a second time, James is working with Dave, a 17-year-old black shirt. They are being sent to investigate Leon Tarasov who runs a garage. When they get to their flat in south London, Dave gets a job at the suspect's garage, and James gets a girlfriend called Hannah. During his first night in the area, James gets into an altercation with two goons and is arrested for it. As he is being placed in the police car, police officer Michael Patel assaults him. Hannah tells James how her cousin, Will, fell off the top of the building more than a year earlier. As James has no computer that she knows of, she gives him Will's old one.
Back home, James finds that Will had a CD with information about a robbery at a casino almost a year earlier. The theft totaled 90,000 but is too small for what they are looking for. Dave later realises that if the casino had an illegal floor with more gambling equipment that was also robbed, then there would be enough money to be what they are looking for. To help find more evidence to capture Michael Patel, Kerry and Lauren join the team. A few days later, Hannah reveals that after Will's death, Patel had deliberately run over to the body and touched it, supposedly to see if he was still alive. James and Dave figure out that that policeman had killed Will.
Question: What is the last name of the person whose room James leaves?
Output: Chang.
