Question: Which ship had been in service longer at the time when he was on them, the one where he still held sub-lieutenant rank or the one where David had been promoted to full lieutenant? Passage:He was assigned as a midshipman on 1 May 1929 after finishing top of his class in five subjects. In 1930 he was assigned to the battleship Marlborough, part of the Third Battle Squadron; and the following year to the battlecruiser in September 1931 on which he served with fellow midshipman, and future vice admiral, Peter Gretton. While serving on the ship, Wanklyn was promoted to acting sub-lieutenant (the equivalent of an army second lieutenant) on 1 January 1932. Soon afterwards he moved to the naval gunnery school - HMS Excellent - at Whale Island, Portsmouth to learn more about naval navigation to qualify for his second ring at the rank of lieutenant. In February 1933 he moved to HMS Dolphin and was promoted to lieutenant on 1 February 1933.

Question: In which venue was the wild card game played in 2014? Passage:Despite having claimed the Wild Card spot on the final day of the regular season, the Giants were able to tab ace Madison Bumgarner for the Wild Card game start. Bumgarner had an excellent regular season for the Giants, finishing with a career-low in ERA and a career-high in strikeouts, finishing fourth in the National League in both categories. On the hill for the New York Mets was Noah Syndergaard, who himself finished 3rd in the NL in ERA and 9th in strikeouts. The pitching matchup didn't disappoint, it took until the bottom of the third inning for the game's first hit and baserunner, with Syndergaard striking out four straight batters on two occasions. The closest either side came to scoring was in the top of the 6th when, after Denard Span singled and stole second base with two outs, Brandon Belt hit a long fly ball to center field which was caught on the dead run by Curtis Granderson, smashing into the wall and holding on. Syndergaard exited after 7 innings, having struck out 10. Crucially as it turned out, the Giants had forced Syndergaard out of the game with Bumgarner still going strong. Another golden opportunity was squandered by the Giants in the top of the 8th inning, when Addison Reed struck out Hunter Pence to end the inning with the bases loaded. After Bumgarner left a runner in scoring position in the bottom of the 8th, the game moved to the 9th with the Mets bringing in closer Jeurys Familia. Brandon Crawford led the inning off with a double to left-center, but Ángel Pagán couldn't lay down the sacrifice bunt and then struck out. Joe Panik worked a walk and Conor Gillaspie stepped up to the plate to launch a three-run home run to right field. Gillaspie had only started the game because Eduardo Núñez was still dealing with a hamstring injury and had to be left off the roster. Bumgarner then got the final three outs, completing the shutout just as he had done in the 2014 Wild Card Game. Bumgarner made 119 pitches, allowed just 6 total baserunners, striking out 6 and setting an MLB record of 23 consecutive scoreless innings pitched in postseason elimination games. With the win, the Giants equalled the Major League record for consecutive postseason series wins with 11, also extending their streak of postseason elimination game wins to 9.

Question: How many years did the war last that Eden's great-grandfather commanded the 2nd regiment of foot? Passage:Eden's great-grandfather was William Iremonger, who commanded the 2nd Regiment of Foot during the Peninsular War and fought under Wellington (as he became) at Vimeiro. He was also descended from Governor Sir Robert Eden, 1st Baronet, of Maryland and, through the Calvert Family of Maryland, he was connected to the ancient Roman Catholic aristocracy of the Arundell and Howard families, some of whom were Roman Catholics like the Dukes of Norfolk and others Anglican such as the earls of Carlisle, Effingham and Suffolk. The Calverts had converted to the Established Church early in the 18th century to regain the proprietorship of Maryland. He was also descendant from the Schaffalitzky de Muckadell family of Denmark, and Bie family of Norway. Eden was once amused to learn that one of his ancestors had, like Churchill's ancestor the Duke of Marlborough, been the lover of Barbara Castlemaine.
