Background: Keane are an English rock band from Battle, East Sussex, formed in 1995. The band currently comprises Tom Chaplin (lead vocals, electric/acoustic guitar), Tim Rice-Oxley (piano, synthesisers, bass guitar, backing vocals), Richard Hughes (drums, percussion, backing vocals), and Jesse Quin (bass guitar, acoustic/electric guitar, backing vocals). Their original line-up included founder and guitarist Dominic Scott, who left in 2001. Keane achieved mainstream, international success with the release of their debut album, Hopes and Fears, in 2004.
Context: In a March 2007 video interview, Chaplin and Hughes spoke of wanting to take a more "organic" approach on album three, but played down suggestions about the use of guitars, referring to them as "a fun part of the live set" at present; however, the cover of "She Sells Sanctuary", became the first song recorded since "The Happy Soldier" (2001) to feature the instrument. Photographic updates to the Keane website also implied the use of guitars in the album's recording sessions. Jesse Quin joined the band since this album as permanent studio and live member. He plays the bass, percussion, guitar, synths and backing vocals. On 25 August 2008, Keane appeared as studio guests on BBC 6 Music with Steve Lamacq where three of the new songs from Perfect Symmetry were played for the first time: "Spiralling", "The Lovers Are Losing", and "Better Than This".  The album was released on 13, October 2008, and reached number one on the UK Albums Chart on 19 October. It also reached number 7 on the Billboard 200 chart. In December 2008, it was voted Best Album of the Year by the readers, listeners and visitors of Q Magazine, Q Radio and Qthemusic.com. The song "Perfect Symmetry" was voted best track.  In November of the same year, they started their third world tour, the Perfect Symmetry World Tour. On 2 April 2009, Keane became the first band ever to broadcast a live show in 3D. It was filmed at Abbey Road, the site of the world's first satellite broadcast (by The Beatles). Keane fans were prompted to buy 3D glasses along with the new 7" single, "Better Than This", or also to hand-make their own glasses. The show is available to watch on Keane's official site in high definition.

Background: Khalid Sheikh Mohammed (sometimes also spelled Khalid Shaikh Mohammed; among at least fifty pseudonyms; born March 1, 1964) is an Islamist militant held by the United States at the Guantanamo Bay detention camp under terrorism-related charges. He was named as "the principal architect of the 9/11 attacks" in the 9/11 Commission Report. Sheikh Mohammed was a member of Osama bin Laden's al-Qaeda organization, leading al-Qaeda's propaganda operations from around 1999 until late 2001. He confessed to FBI and CIA agents to a role in many of the most significant terrorist plots over the last twenty years, but his interrogators' use of enhanced interrogation techniques has caused some to question certain aspects of his confessions.
Context: By the time the Bojinka plot was discovered, Mohammed had returned to Qatar and his job as a project engineer at the country's Ministry of Electricity and Water. He traveled in 1995 to Sudan, Yemen, Malaysia, and Brazil to visit elements of the worldwide jihadist community, although no evidence connects him to specific terrorist actions in any of those locations. On his trip to Sudan, he attempted to meet with Osama Bin Laden, who was at the time living there, aided by Sudanese political leader Hassan al-Turabi. After the US asked the Qatari government to arrest Mohammed in January 1996, he fled to Afghanistan, where he renewed his alliance with Abdul Rasul Sayyaf. Later that year, he formed a working relationship with Bin Laden, who had settled there.  Bin Laden and his colleagues relocated their operations to Afghanistan at this time. Abu Hafs al-Masri/Mohammed Atef, bin Laden's chief of operations, arranged a meeting between bin Laden and Mohammed in Tora Bora sometime in mid-1996, in which Mohammed outlined a plan that would eventually become the quadruple hijackings of 2001. Bin Laden urged Mohammed to become a full-fledged member of Al Qaeda, but he continued to refuse such a commitment until around early 1999, after the 1998 U.S. embassy bombings in Nairobi and Dar es Salaam.  Mohammed moved his family from Iran to Karachi, Pakistan, in 1997. That year, he tried unsuccessfully to join mujahideen leader Ibn al-Khattab in Chechnya, another area of special interest to Mohammed. Unable to travel to Chechnya, he returned to Afghanistan. He ultimately accepted bin Laden's invitation to move to Kandahar and join al-Qaeda as a full-fledged member. Eventually, he became leader of Al Qaeda's media committee.
Question: what was his greatest accomplishment?
Answer: Eventually, he became leader of Al Qaeda's media committee.

Background: David was born on 28 January 1858, in St. Fagans near Cardiff, Wales, the eldest son of the Rev. William David, a fellow of Jesus College, Oxford, a classical scholar and naturalist and his wife Margaret Harriette (nee Thomson). His mother's cousin, William A. E. Ussher of the Geological Survey, first interested David in what was to be his life work. At the age of 12, David went to Magdalen College School, Oxford in 1870. In 1876 he gained a classical scholarship to New College, Oxford.
Context: In 1896 the Davids bought 26 acres (10.5 hectares) at Woodford, in the Blue Mountains, with an existing weatherboard cottage, two-roomed with two skillion rooms at the back. To emphasise his Welsh origins, Edgeworth David named the Woodford cottage 'Tyn-y-Coed', the 'house in the trees' (often mistranslated as 'the shack in the bush': 'ty' is a proper house in Welsh, not a mere hut).  In 1915 the Davids offered their home to the Red Cross convalescent home for the rehabilitation of injured servicemen and the Woodford Academy boys erected a flagstaff for the Union Jack and Red Cross flags for the soldiers in residence. When the Cooee marchers trooped past in November 1915 some of the wounded soldiers were brought up to the main road to greet the marchers. Although they had work and commitments in Sydney, Woodford was the David's primary residence from 1899 until 1920. They retained the Woodford cottage as a favoured country retreat until Edgeworth's death in 1934. Tyn-y-Coed was destroyed by bushfire in 1944 with only a chimney stump remaining. Its grounds are now occupied by eight modern houses, their gardens and adjoining bush.  In September 1920, David was created a Knight Commander of the Order of the British Empire for services during the war.  Returning to Australia, David purchased Coringah, a cottage in the Sydney suburb of Hornsby. He also took up a long-cherished project, the writing of a definitive work, The Geology of the Commonwealth of Australia. In 1921-22 David helped set up the Australian National Research Council and served as its first President. In 1924 he retired as Professor of Geology at the University of Sydney, the chair passing to his student Leo Cotton, a neighbour in Hornsby, New South Wales, whose brother Max Cotton created Lisgar Gardens in Hornsby. In 1928 he discovered what he believed were Precambrian fossils, creating controversy which remained until his death.  In 1931 he published the Geological Map of the Commonwealth and the accompanying Explanatory Notes, designed to be part of his Geology of the Commonwealth of Australia. He died in 1934 without being able to complete this work and was given a state funeral.
