Input: Consider Input: Question: What were the combined ages of Joseph Urban and Benjamin Wistar Morris the year that they were both hired to come up with blueprints for the house? Passage:The construction of Rockefeller Center occurred between 1932 and 1940 on land that John D. Rockefeller Jr. leased from Columbia University. The Rockefeller Center site was originally supposed to be occupied by a new opera house for the Metropolitan Opera. By 1928, Benjamin Wistar Morris and designer Joseph Urban were hired to come up with blueprints for the house. However, the new building was too expensive for the opera to fund by itself, and it needed an endowment, and the project ultimately gained the support of John D. Rockefeller Jr. The planned opera house was canceled in December 1929 due to various issues, with the new opera house eventually being built at Lincoln Center, opening in 1966.

Input: Consider Input: Question: What is the square area in miles of the city where Ardley was born? Passage:Ardley was born in Epsom, Surrey. Signed by Wimbledon as a youngster, whilst at Carshalton Boys Sports College, he made his way through the youth set up until breaking into the first team. Ardley made eight league appearances for Wimbledon in the 1991–92 season, featuring more prominently in the 1992–93 campaign, in which he played in 26 games and scored four goals in the inaugural season of the FA Premier League as the Dons finished 12th. Wimbledon finished 6th in the FA Premier League in 1993–94, matching the record highest ranking achieved by the club during their first ever season in the top flight during 1986–87. Ardley's contribution was more limited during this season, however, as he was selected to play in just 16 games. He scored just once in a 2–1 win over Sheffield Wednesday on 15 January 1994. He was in and out of the side for nearly a decade afterwards, remaining with the Dons after their relegation at the end of 1999–2000. Two more seasons followed as he unsuccessfully tried to help them regain their Premier League place, before he signed for Division One rivals Watford on a free transfer on 9 August 2002.
