Teacher: Now, understand the problem? Solve this instance: 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 1: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.
 Passage 2:After three singles, The White Stripes released their self-titled debut album in June 1999. Their second studio album, the well-received De Stijl, followed in June 2000. The band's third studio album, White Blood Cells, became their breakthrough album, receiving much acclaim while pushing the band to the forefront of alternative rock. They later signed to V2 Records and released their fourth studio album Elephant in April 2003. The album was a commercial success, peaking at number six on the US Billboard 200 and reaching the top ten in multiple other countries. Elephant has been certified platinum by the Recording Industry Association of America (RIAA). The album spawned the single "Seven Nation Army", which topped the US Billboard Alternative Songs chart and became the group's first appearance on the US Billboard Hot 100, where it peaked at number 76.
 Passage 3:Over the years, Pahang grew independent from Melakan control and at one point even established itself as a rival state to Melaka until the latter's demise in 1511. At the height of its influence, the Sultanate was an important power in Southeast Asian history and controlled the entire Pahang basin, bordering to the north, the Pattani Sultanate, and adjoins to that of Johor Sultanate to the south. To the west, it also extends jurisdiction over part of modern-day Selangor and Negeri Sembilan.. During this period, Pahang was heavily involved in attempts to rid the Peninsula of the various foreign imperial powers; Portugal, Holland and Aceh. After a period of Acehnese raids in the early 17th century, Pahang entered into the amalgamation with the successor of Melaka, Johor, when its 14th Sultan, Abdul Jalil Shah III, was also crowned the 7th Sultan of Johor. After a period of union with Johor, it was eventually revived as a modern sovereign Sultanate in the late 19th century by the Bendahara dynasty.
