Input: Copyright infringement
In Europe, the copyright infringement case Public Relations Consultants Association Ltd v Newspaper Licensing Agency Ltd had two prongs; one concerned whether a news aggregator service infringed the copyright of the news generators; the other concerned whether the temporary web cache created by the web browser of a consumer of the aggregator's service, also infringed the copyright of the news generators. The first prong was decided in favor of the news generators; in June 2014 the second prong was decided by the Court of Justice of the European Union (CJEU), which ruled that the temporary web cache of consumers of the aggregator did not infringe the copyright of the news generators.

What did the courts rule was NOT infringement?
Output: temporary web cache of consumers

Input: Military history of the United States
Before the war, many observers believed the US and its allies could win but might suffer substantial casualties (certainly more than any conflict since Vietnam), and that the tank battles across the harsh desert might rival those of North Africa during World War II. After nearly 50 years of proxy wars, and constant fears of another war in Europe between NATO and the Warsaw Pact, some thought the Persian Gulf War might finally answer the question of which military philosophy would have reigned supreme. Iraqi forces were battle-hardened after 8 years of war with Iran, and they were well equipped with late model Soviet tanks and jet fighters, but the antiaircraft weapons were crippled; in comparison, the US had no large-scale combat experience since its withdrawal from Vietnam nearly 20 years earlier, and major changes in US doctrine, equipment and technology since then had never been tested under fire.

What conflict was supposed to have provided Iraqi forces with battle experience?
Output: 8 years of war with Iran

Input: Detroit
On February 18, 2015, Canadian Transport Minister Lisa Raitt announced that Canada has agreed to pay the entire cost to build a $250 million U.S. Customs plaza adjacent to the planned new Detroit–Windsor bridge, now the Gordie Howe International Bridge. Canada had already planned to pay for 95 per cent of the bridge, which will cost $2.1 billion, and is expected to open in 2020. "This allows Canada and Michigan to move the project forward immediately to its next steps which include further design work and property acquisition on the U.S. side of the border," Raitt said in a statement issued after she spoke in the House of Commons. 

How much is the Gordie Howe International Bridge expected to cost?
Output: $2.1 billion

Input: Bird migration
Birds need to alter their metabolism in order to meet the demands of migration. The storage of energy through the accumulation of fat and the control of sleep in nocturnal migrants require special physiological adaptations. In addition, the feathers of a bird suffer from wear-and-tear and require to be molted. The timing of this molt - usually once a year but sometimes twice - varies with some species molting prior to moving to their winter grounds and others molting prior to returning to their breeding grounds. Apart from physiological adaptations, migration sometimes requires behavioural changes such as flying in flocks to reduce the energy used in migration or the risk of predation.

Why do birds need to molt?
Output:
feathers of a bird suffer from wear-and-tear
