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?

Ex Output:
diabetes.

Passage: Starr was inducted into the Percussive Arts Society Hall of Fame in 2002, joining an elite group including Buddy Rich, William F. Ludwig Sr. and William F. Ludwig Jr. On 29 November 2002 (the first anniversary of Harrison's death), he performed "Photograph" and a cover of Carl Perkins' "Honey Don't" at the Concert for George held in the Royal Albert Hall, London. Early the following year, he released the album Ringo Rama, which contained a song he co-wrote as a tribute to Harrison, "Never Without You". Also in 2003, he formed Pumkinhead Records with All-Starr Band member Mark Hudson. The label was not prolific, but their first signing was Liam Lynch, who produced a 2003 LP entitled Fake Songs.Starr served as an honorary Santa Tracker and voice-over personality in 2003 and 2004 during the London stop in Father Christmas's annual Christmas Eve journey, as depicted in the annual NORAD tracks Santa program. According to NORAD officials, he was "a Starr in the east" who helped guide North American Aerospace Defense Command's Santa-tracking tradition.
His 2005 release Choose Love eschewed the star-guests approach of his last two studio albums but failed to chart in the UK or the US. That same year, Liverpool's City Council announced plans to demolish Starr's birthplace, 9 Madryn Street, stating that it had "no historical significance". The LCC later announced that the building would be taken apart brick by brick and preserved.Starr released the album Liverpool 8 in January 2008, coinciding with the start of Liverpool's year as the European Capital of Culture. Hudson was the initial producer of the recordings, but after a falling out with Starr, he was replaced by David A. Stewart. Starr performed the title track at the opening ceremony for Liverpool's appointment, but thereafter attracted controversy over his seemingly unflattering comments about his city of birth. Later that year, he was the object of further criticism in the press for posting a video on his website in which he harangued fans and autograph hunters for sending him items to sign.In April 2009, he reunited with McCartney at the David Lynch Foundation's "Change Begins Within" benefit concert, held at New York's Radio City Music Hall. Having played his own set beforehand, Starr joined McCartney for the finale and performed "With a Little Help from My Friends", among other songs. Starr also appeared on-stage during Microsoft's June 2009 E3 press conference with Yoko Ono, McCartney and Olivia Harrison to promote The Beatles: Rock Band video game. In November 2009, he once again performed the voice of Thomas the Tank Engine for "The Official BBC Children in Need Medley". 
Question: What is the name of the person that released Ringo Rama?

Ex Output:
Starr.

Passage: The first group of people claiming to be an ambassadorial mission of Romans to China was recorded as having arrived in 166 AD by the Book of the Later Han. The embassy came to Emperor Huan of Han China from "Andun" (Chinese: 安敦; Emperor Antoninus Pius or Marcus Aurelius Antoninus), "king of Daqin" (Rome). As Antoninus Pius died in 161 AD, leaving the empire to his adoptive son Marcus Aurelius Antoninus, and the envoy arrived in 166 AD, confusion remains about who sent the mission, as both emperors were named "Antoninus". The Roman mission came from the south (therefore probably by sea), entering China by the frontier of Rinan or Tonkin (present-day Vietnam). It brought presents of rhinoceros horns, ivory, and tortoise shell, probably acquired in Southern Asia. The text states that it was the first time there had been direct contact between the two countries. Yule speculated that the Roman visitors must have lost their original wares due to robbery or shipwreck and used the gifts instead, prompting Chinese sources to suspect them of withholding their more precious valuables, which Yule notes was the same criticism directed at papal missionary John of Montecorvino when he arrived in China in the late 13th century AD. Historians Rafe de Crespigny, Peter Fibiger Bang, and Warwick Ball believe that this was most likely a group of Roman merchants rather than official diplomats sent by Marcus Aurelius. Crespigny stresses that the presence of this Roman embassy as well as others from Tianzhu (in northern India) and Buyeo (in Manchuria) provided much-needed prestige for Emperor Huan, as he was facing serious political troubles and fallout for the forced suicide of politician Liang Ji, who had dominated the Han government well after the death of his sister Empress Liang Na. Yule emphasised that the Roman embassy was said to come by way of Jiaozhi in northern Vietnam, the same route that Chinese sources claimed the embassies from Tianzhu (northern India) had used in 159 and 161 AD. 
Question: What was the name of Liang Ji's sister?

Ex Output:

Empress Liang Na.
