Input: Consider Input: Question: How many different teams did the player Lakin replaced at  in the 2017–18 FA Cup play for? Passage:His involvement with Birmingham's first team increased, and on 27 January 2018, he was given a squad number and included among the substitutes for the FA Cup fourth-round visit to Premier League club Huddersfield Town. He remained unused as Birmingham drew the match, but made his senior debut in the replay ten days later. Use of a fourth substitute during extra time of an FA Cup tie, trialled in the later rounds of the 2016–17 edition, was permitted from the first round in 2017–18. Lakin became the first Birmingham player to be used under that arrangement when he replaced Jason Lowe after 101 minutes with his team already 3–1 down; the match finished as a 4–1 defeat. According to the Birmingham Mail, on his first involvement in the match, "he gathered possession on the edge of his own area, surged through his half and threaded a superb pass to Jota which set Blues away on the counter", showing the "sort of technical ability which has made him such a big hit in his first full season at Under 23 level." Two weeks later, Lakin signed a new contract to run until 2020, with a further one-year option in the club's favour.

Input: Consider Input: Question: How many albums total did the Beatles record in Hamburg? Passage:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.

Input: Consider Input: Question: Where was the division based that was able to dig in for a defense of Bastogne? Passage:The 9th Armored Division landed in Normandy late in September 1944, and first went into the line, 23 October 1944, on patrol duty in a quiet sector along the Luxembourg-German frontier. When the Germans launched their winter offensive on 16 December 1944, the 9th, with no real combat experience, suddenly found itself engaged in heavy fighting. The Division saw its severest action at St. Vith, Echternach, and Bastogne, its units fighting in widely separated areas. Its stand at Bastogne held off the Germans long enough to enable the 101st Airborne Division to dig in for a defense of the city. After a rest period in January 1945, the Division prepared to drive across the Roer River. The offensive was launched on 28 February 1945 and the 9th crossed the Roer to Rheinbach, sending patrols into Remagen. On 7 March 1945, elements of the 9th Armored found that the Ludendorff Bridge was still standing. When German demolition charges failed to bring the bridge down, they crossed it, disarming and removing the remaining charges, which could have exploded at any time. The Division exploited the bridgehead, moving south and east across the Lahn River toward Limburg, where thousands of Allied prisoners were liberated from Stalag XIIA. The Division drove on to Frankfurt and then turned to assist in the closing of the Ruhr Pocket. In April it continued east, encircling Leipzig and securing a line along the Mulde River. The Division was shifting south to Czechoslovakia when the war in Europe ended on 9 May 1945. All units of CCB/9 AIB of the 9th Armored Division were awarded the Presidential Unit Citation for their actions in taking and defending the Ludendorff Bridge during the Battle of Remagen in World War II.
