Input: Anti-aircraft warfare
Poland's AA defences were no match for the German attack and the situation was similar in other European countries. Significant AA warfare started with the Battle of Britain in the summer of 1940. 3.7-inch HAA were to provide the backbone of the groundbased AA defences, although initially significant numbers of 3-inch 20-cwt were also used. The Army's Anti-aircraft command, which was under command of the Air Defence UK organisation, grew to 12 AA divisions in 3 AA corps. 40-mm Bofors entered service in increasing numbers. In addition the RAF regiment was formed in 1941 with responsibility for airfield air defence, eventually with Bofors 40mm as their main armament. Fixed AA defences, using HAA and LAA, were established by the Army in key overseas places, notably Malta, Suez Canal and Singapore.

What battle marked the beginning of significant antiaircraft warfare?
Output: Battle of Britain

Input: YouTube
YouTube entered into a marketing and advertising partnership with NBC in June 2006. In November 2008, YouTube reached an agreement with MGM, Lions Gate Entertainment, and CBS, allowing the companies to post full-length films and television episodes on the site, accompanied by advertisements in a section for US viewers called "Shows". The move was intended to create competition with websites such as Hulu, which features material from NBC, Fox, and Disney. In November 2009, YouTube launched a version of "Shows" available to UK viewers, offering around 4,000 full-length shows from more than 60 partners. In January 2010, YouTube introduced an online film rentals service, which is available only to users in the US, Canada and the UK as of 2010. The service offers over 6,000 films.

What was the intended purpose of youtube's "shows" section?
Output: to create competition

Input: Valencia
Valencia enjoyed strong economic growth over the last decade, much of it spurred by tourism and the construction industry,[citation needed] with concurrent development and expansion of telecommunications and transport. The city's economy is service-oriented, as nearly 84% of the working population is employed in service sector occupations[citation needed]. However, the city still maintains an important industrial base, with 5.5% of the population employed in this sector. Agricultural activities are still carried on in the municipality, even though of relatively minor importance with only 1.9% of the working population and 3973 hectares planted mostly in orchards and citrus groves.

What are Valencia's agricultural areas mainly planted with?
Output: orchards and citrus groves

Input: Strasbourg
Strasbourg also offers high-class eclecticist buildings in its very extended German district, the Neustadt, being the main memory of Wilhelmian architecture since most of the major cities in Germany proper suffered intensive damage during World War II. Streets, boulevards and avenues are homogeneous, surprisingly high (up to seven stories) and broad examples of German urban lay-out and of this architectural style that summons and mixes up five centuries of European architecture as well as Neo-Egyptian, Neo-Greek and Neo-Babylonian styles. The former imperial palace Palais du Rhin, the most political and thus heavily criticized of all German Strasbourg buildings epitomizes the grand scale and stylistic sturdiness of this period. But the two most handsome and ornate buildings of these times are the Ecole internationale des Pontonniers (the former Hohere Madchenschule, girls college) with its towers, turrets and multiple round and square angles and the Ecole des Arts decoratifs with its lavishly ornate facade of painted bricks, woodwork and majolica.

What war caused severe damage to Germany?
Output:
World War II
