Input: Consider Input: Question: Which wrestler who headlined the Cyber Sunday feud in WWE was born first? Passage:The main feud heading into Cyber Sunday was between WWE Champion John Cena, World Heavyweight Champion King Booker, and ECW World Champion The Big Show, the top champion of each of the three brands. This feud began on the October 9 edition of Raw, where they came face to face, arguing about who was the most dominant champion in WWE. WWE Chairman Vince McMahon interrupted, and booked a triple threat "Champion of Champions" match at Cyber Sunday between the three of them. This also gave each show's General Manager an opportunity to choose opponents for each other's champion that night. This resulted in Big Show defeating Jeff Hardy and Booker defeating Rob Van Dam; however, the match between Cena and The Undertaker was interrupted by Booker, Big Show, and The Undertaker's storyline rival, Mr. Kennedy. At the same time, Cena began a minor feud with Kevin Federline. Federline, as the on-screen close friend of Johnny Nitro and Melina's, appeared on Raw to promote his album, "Playing With Fire". Cena rapped about Federline, but Nitro came out to Federline's defense and was thrown out of the ring by Cena. Cena was then interrupted by his two Cyber Sunday opponents, and McMahon who announced that a championship would be on the line at Cyber Sunday. Cena performed the FU on Federline, after being insulted. The feud between the champions continued on the October 20 edition of SmackDown!, when Big Show and Cena were at ringside during Booker's title defense against Batista. Batista speared Booker onto Big Show, who, in response, assaulted Batista, ending the match via disqualification. Cena then joined the brawl, and SmackDown! General Manager Theodore Long announced a tag team match for the next week. On the next Raw, Cena defeated Nitro after an FU, but was assaulted afterwards by his Cyber Sunday opponents, who turned on each other shortly after to start a brawl between the four to end the show. Batista and Cena were successful in the tag team match, after Big Show abandoned Booker. The next week, on Raw, a preview of Cyber Sunday's interactivity was displayed when fans voted for Cena's opponent for the night, between Big Show, Booker, and Jonathan Coachman. Coachman won in the voting, but was easily defeated by Cena.

Input: Consider Input: Question: How many years were there between the re-forming of the 20 Battery Royal Artillery and the beginning of the Cuban missile crisis? Passage:After the Second World War the Battery was re-formed in 1955 as 20 Medium Battery as part of 21 Med Regt based at Redford Barracks, Edinburgh but deployed in the Internal Security role to Cyprus in 1956 where the Regt lost several men to the EOKA terrorists. Re-numbered again and re-rolled (a change of equipment and role) as an Amphibious Operations (AO) Battery. They were posted to Hong Kong and renamed 20 Commando (AO) Battery as part of 29 Commando Regiment. Due to the fact that only 20 and 148 Commando (AO) Battery fulfilled the AO roll there was a lot of movement between the batteries most men serving in both. The battery had absorbed 3 (AO) Troop on their move to Hong Kong and was involved in a number of operations including the Korean War and a little known operation in the Caribbean during the Cuban missile crisis. The Battery was involved in clearing Russian, American and Cuban personnel off remote Caribbean islands in the region and arrested 60 men who later turned out to be CIA operatives, causing a minor political incident. The Battery was placed into suspended animation in 1969 following the downsizing of the British Army and the reduction to one Commando Artillery Regiment, having lost out to 148 Commando (AO) Battery. Many of 20 Commando (AO) Battery's personnel ended up in 148 Battery and so did much of the battery property.
