[EX Q]: Question: Which of the two rock musicians that appeared in "The Secret Policeman's Ball" recorded an album first? Passage:Ball co-founder Cleese and Jones had an involvement (as performer, writer or director) in all four Amnesty benefit shows, Palin in three, Chapman in two, and Gilliam in one. Idle did not participate in the Amnesty shows. Notwithstanding Idle's lack of participation, the other five members (together with "Associate Pythons" Carol Cleveland and Neil Innes) all appeared together in the first Secret Policeman's Ball benefitthe 1976 A Poke in the Eye held at Her Majesty's Theatre in London's West Endwhere they performed several Python sketches. In this first show, they were collectively billed as Monty Python. Peter Cook deputised for the errant Idle in a courtroom sketch. In the next three shows, the participating Python members performed many Python sketches, but were billed under their individual names rather than under the collective Python banner. The second show featured newcomer Rowan Atkinson and Scottish comedian Billy Connolly. The Secret Policeman's Ball were the first stage shows in the UK to present comedic performers (such as Monty Python and Rowan Atkinson) in the same setting and shows as their contemporaries in rock music (which included Eric Clapton, Sting and Phil Collins). After a six-year break, Amnesty resumed producing Secret Policeman's Ball benefit shows which were held at the London Palladium in 1987 (sometimes with, and sometimes without, variants of the iconic title) and by 2006 had presented a total of 12 such shows. The shows since 1987 have featured newer generations of British comedic performers, such as Stephen Fry, Hugh Laurie, and puppets from the satirical TV show Spitting Image, with many attributing their participation in the show to their desire to emulate the Python's pioneering work for Amnesty. Cleese and Palin made a brief cameo appearance in the 1989 Amnesty show; apart from that, the Pythons have not appeared in shows after the first four."

[EX Q]: Question: Why was the Yuan dynasty considered chaotic? Passage:The Xia (13621371), officially the Great Xia and known as Ming Xia today, was a short-lived Chinese dynasty in modern Sichuan and Chongqing during the chaotic late Yuan dynasty. It was founded by the Red Turban rebel general Ming Yuzhen whose army expelled Yuan loyalists from the region in the late 1350s. He refused to recognize Chen Youliang, who killed the Red Turban leader Xu Shouhui to found his Chen Han empire, so in 1362 Ming declared himself emperor of Xia, with the capital in Chongqing. He defended his empire from Chen Han, and tried, unsuccessfully, to conquer Yunnan from the warlord Basalawarmi. After his death in 1366, his teenaged son Ming Sheng succeeded him, but the empire began to disintegrate into regional military commands. In 1371, the Ming dynasty under emperor Zhu Yuanzhang made a two-pronged attack and conquered Xia relatively easily. Ming Sheng who surrendered was exiled to Goryeo, and became the progenitor of the Korean Namwon Seung clan, Yeonan Myeong clan and Seochok Myeong clan.
