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 benefit—the 1976 A Poke in the Eye held at Her Majesty's Theatre in London's West End—where 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."

Question: Who was the last leader of the the country that was established after the year-long siege in 831? Passage:At the time of his accession, Theophilos was obliged to wage wars against the Arabs on two fronts. Sicily was once again invaded by the Arabs, who took Palermo after a year-long siege in 831, established the Emirate of Sicily, and gradually continued to expand across the island. The defence after the invasion of Anatolia by the Abbasid Caliph Al-Ma'mun in 830 was led by the Emperor himself, but the Byzantines were defeated and lost several fortresses. In 831 Theophilos retaliated by leading a large army into Cilicia and capturing Tarsus. The Emperor returned to Constantinople in triumph, but in the autumn he was defeated in Cappadocia. Another defeat in the same province in 833 forced Theophilos to sue for peace (Theophilos offered 100,000 gold dinars and the return of 7,000 prisoners), which he obtained the next year, after the death of Al-Ma'mun.

Question: How many Hawaiian Islands are there? Passage:The Island of Hawaii was first inhabited by Polynesians who arrived in canoes and spread to the other Hawaiian islands. After the contact by the British explorer James Cook the islands became well known and Europeans came and inhabited them. The French government was interested in the islands and wanted to establish Catholicism. The Kingdom of Hawaii became more influenced by the United States which set up trade relations with the Kingdom. After the overthrow of the Hawaiian Kingdom in 1893, the new Republic of Hawaii government lobbied for annexation by the United States. Annexation was approved by President William McKinley and Hawaii was incorporated as part of the territory of the United States on August 12, 1898, and then, in April 1900, organized as the territory of Hawaii.
