Question: What is the population of the country where Imelda May's fifth studio album was first released?   Passage:Life Love Flesh Blood is the fifth studio album by Irish singer-songwriter Imelda May. It was first released in the Republic of Ireland on 7 April 2017, through label Decca Records, followed by a worldwide release two weeks later on 21 April 2017. The album, a follow-up to May's previous album Tribal (2014), was created in collaboration with American musician T Bone Burnett. Serving as the primary producer for the record, Burnett was only credited alongside Scottish producer Cam Blackwood. Blackwood produced a duet version of the album's lead single "Call Me", recorded with English vocalist Jack Savoretti, included on streaming editions of the album post-release. Throughout the album's creative process, May received guidance from Irish musician Bono, of rock group U2. The album followed May's divorce from guitarist Darrel Higham, influencing many lyrical themes on the album. Life Love Flesh Blood features soft rock and acoustic styles, differing significantly from the rockabilly genre of previous albums.

Question: Of the waters David became an experienced sailor, which one is deeper? Passage:Born into a poor family in Linlithgowshire in Scotland, Bartholomew joined the Merchant Navy at a young age and became a highly experienced sailor, travelling to the Baltic Sea and the West Indies, working on hired merchant ships during campaigns against French islands there at the outbreak of the French Revolutionary Wars. He later served on Greenland whalers, but in 1795 was seized by a press gang at Wapping and forcibly recruited into the Royal Navy. Due a superior education (although where he obtained this education is unknown), Bartholomew was rapidly promoted to midshipman, serving in numerous theatres and becoming a favourite of Admiral Sir Home Riggs Popham. Bartholomew was present at the surrender of the Dutch fleet in 1799, on HMS Romney in the East Indies and in 1802 was in charge of the ship's chronometers during a voyage to the Red Sea. The Peace of Amiens in the same year saw a reduction in the Navy and Bartholomew was placed in reserve.
