Input: Consider Input: Passage: In February 2012, Capello resigned from his role as England manager, following a disagreement with the FA over their request to remove John Terry from team captaincy after accusations of racial abuse concerning the player. Following this, there was media speculation that Harry Redknapp would take the job. However, on 1 May 2012, Roy Hodgson was announced as the new manager, just six weeks before UEFA Euro 2012. England managed to finish top of their group, winning two and drawing one of their fixtures, but exited the Championships in the quarter-finals via a penalty shoot-out, this time to Italy.

Output: In what year was Capello made England's manager?

Input: Consider Input: Passage: Sichuan came under the firm control of a Chinese central government during the Sui dynasty, but it was during the subsequent Tang dynasty where Sichuan regained its previous political and cultural prominence for which it was known during the Han. Chengdu became nationally known as a supplier of armies and the home of Du Fu, who is sometimes called China's greatest poet. During the An Lushan Rebellion (755-763), Emperor Xuanzong of Tang fled from Chang'an to Sichuan. The region was torn by constant warfare and economic distress as it was besieged by the Tibetan Empire.

Output: Who regained their prominence under the Sui dynasty?

Input: Consider Input: Passage: A "grand", sometimes shortened to simply "G", is a common term for the amount of $1,000. The suffix "K" or "k" (from "kilo-") is also commonly used to denote this amount (such as "$10k" to mean $10,000). However, the $1,000 note is no longer in general use. A "large" or "stack", it is usually a reference to a multiple of $1,000 (such as "fifty large" meaning $50,000). The $100 note is nicknamed "Benjamin", "Benji", "Ben", or "Franklin" (after Benjamin Franklin), "C-note" (C being the Roman numeral for 100), "Century note" or "bill" (e.g. "two bills" being $200). The $50 note is occasionally called a "yardstick" or a "grant" (after President Ulysses S. Grant, pictured on the obverse). The $20 note is referred to as a "double sawbuck", "Jackson" (after Andrew Jackson), or "double eagle". The $10 note is referred to as a "sawbuck", "ten-spot" or "Hamilton" (after Alexander Hamilton). The $5 note as "Lincoln", "fin", "fiver" or "five-spot". The infrequently-used $2 note is sometimes called "deuce", "Tom", or "Jefferson" (after Thomas Jefferson). The $1 note as a "single" or "buck". The dollar has also been, referred to as a "bone" and "bones" in plural (e.g. "twenty bones" is equal to $20). The newer designs, with portraits displayed in the main body of the obverse rather than in cameo insets upon paper color-coded by denomination, are sometimes referred to as "bigface" notes or "Monopoly money".
