Input: Article: A major problem in the managing of the Luftwaffe was Hermann Göring. Hitler believed the Luftwaffe was "the most effective strategic weapon", and in reply to repeated requests from the Kriegsmarine for control over aircraft insisted, "We should never have been able to hold our own in this war if we had not had an undivided Luftwaffe". Such principles made it much harder to integrate the air force into the overall strategy and produced in Göring a jealous and damaging defence of his "empire" while removing Hitler voluntarily from the systematic direction of the Luftwaffe at either the strategic or operational level. When Hitler tried to intervene more in the running of the air force later in the war, he was faced with a political conflict of his own making between himself and Göring, which was not fully resolved until the war was almost over. In 1940 and 1941, Göring's refusal to cooperate with the Kriegsmarine denied the entire Wehrmacht military forces of the Reich the chance to strangle British sea communications, which might have had strategic or decisive effect in the war against the British Empire.

Now answer this question: Who did Goring refuse to work with in 1940 and 1941?

Output: the Kriegsmarine

Input: Article: The city's airport was Plymouth City Airport about 4 miles (6 km) north of the city centre. The airport was home to the local airline Air Southwest, which operated flights across the United Kingdom and Ireland. In June 2003, a report by the South West RDA was published looking at the future of aviation in the south-west and the possible closure of airports. It concluded that the best option for the south-west was to close Plymouth City Airport and expand Exeter International Airport and Newquay Cornwall Airport, although it did conclude that this was not the best option for Plymouth. In April 2011, it was announced that the airport would close, which it did on 23 December. However, FlyPlymouth plans to reopen the city airport by 2018, which will provide daily services to various destinations including London.

Now answer this question: What local airport closed in 2011?

Output: Plymouth City Airport

Input: Article: In the latter half of the 19th century the locale of South Kensington was developed as "Albertopolis", a cultural and scientific quarter. Three major national museums are there: the Victoria and Albert Museum (for the applied arts), the Natural History Museum and the Science Museum. The National Portrait Gallery was founded in 1856 to house depictions of figures from British history; its holdings now comprise the world's most extensive collection of portraits. The national gallery of British art is at Tate Britain, originally established as an annexe of the National Gallery in 1897. The Tate Gallery, as it was formerly known, also became a major centre for modern art; in 2000 this collection moved to Tate Modern, a new gallery housed in the former Bankside Power Station.

Now answer this question: London's Tate Britain and Tate Modern galleries were formerly one entity known as what?

Output:
The Tate Gallery
