Q: I know that the answer to the question "When was the airfield used?" is in "In May 1940, the US requested base rights in Bermuda from the United Kingdom, but British Prime Minister Winston Churchill was initially unwilling to accede to the American request without getting something in return. In September 1940, as part of the Destroyers for Bases Agreement, the UK granted the US base rights in Bermuda. Bermuda and Newfoundland were not originally included in the agreement, but both were added to it, with no war material received by the UK in exchange. One of the terms of the agreement was that the airfield the US Army built would be used jointly by the US and the UK (which it was for the duration of the war, with RAF Transport Command relocating there from Darrell's Island in 1943).". Can you tell me what it is?

Q: I know that the answer to the question "what is the last place mentioned?" is in "A year before Alfonso III "the Great" of Asturias death, three of Alfonso's sons rose in rebellion and forced him to abdicate, partitioning the kingdom among them. The eldest son, García, became king of León. The second son, Ordoño, reigned in Galicia, while the third, Fruela, received Asturias with Oviedo as his capital. Alfonso died in Zamora, probably in 910. His former realm would be reunited when first García died childless and León passed to Ordoño. He in turn died when his children were too young to ascend; Fruela became king of a reunited crown. His death the next year initiated a series of internecine struggles that led to unstable succession for over a century. It continued under that name[clarification needed] until incorporated into the Kingdom of Castile in 1230, after Ferdinand III became joint king of the two kingdoms. This was done to avoid dynastic feuds and to maintain the Christian Kingdoms strong enough to prevent complete Muslim take over of the Iberian Peninsula and to further the Reconquista of Iberia by Christian armies.". Can you tell me what it is?
A: Iberia

Q: I know that the answer to the question "What came before the new Yankee Stadium?" is in "New York City is home to the headquarters of the National Football League, Major League Baseball, the National Basketball Association, the National Hockey League, and Major League Soccer.

The city has played host to over forty major professional teams in the five sports and their respective competing leagues, both current and historic. Four of the ten most expensive stadiums ever built worldwide (MetLife Stadium, the new Yankee Stadium, Madison Square Garden, and Citi Field) are located in the New York metropolitan area.

Q: I know that the answer to the question "Which is not a last name, Leibniz or Principle?" is in "Arguing against the absolutist position, Leibniz offers a number of thought experiments with the purpose of showing that there is contradiction in assuming the existence of facts such as absolute location and velocity. These arguments trade heavily on two principles central to his philosophy: the principle of sufficient reason and the identity of indiscernibles. The principle of sufficient reason holds that for every fact, there is a reason that is sufficient to explain what and why it is the way it is and not otherwise. The identity of indiscernibles states that if there is no way of telling two entities apart, then they are one and the same thing.". Can you tell me what it is?
A:
principle
