Input: Circadian rhythm
Mutations or deletions of clock gene in mice have demonstrated the importance of body clocks to ensure the proper timing of cellular/metabolic events; clock-mutant mice are hyperphagic and obese, and have altered glucose metabolism. In mice, deletion of the Rev-ErbA alpha clock gene facilitates diet-induced obesity and changes the balance between glucose and lipid utilization predisposing to diabetes. However, it is not clear whether there is a strong association between clock gene polymorphisms in humans and the susceptibility to develop the metabolic syndrome.

What is the body clock gene in animals necessary to ensure?
Output: cellular/metabolic events

Input: Copyright infringement
Article 10 of the Berne Convention mandates that national laws provide for limitations to copyright, so that copyright protection does not extend to certain kinds of uses that fall under what the treaty calls "fair practice," including but not limited to minimal quotations used in journalism and education. The laws implementing these limitations and exceptions for uses that would otherwise be infringing broadly fall into the categories of either fair use or fair dealing. In common law systems, these fair practice statutes typically enshrine principles underlying many earlier judicial precedents, and are considered essential to freedom of speech.

What does Article 10 of the Berne Convention call certain uses that limit copyright?
Output: fair practice

Input: FC Barcelona
After the construction was complete there was no further room for expansion at Les Corts. Back-to-back La Liga titles in 1948 and 1949 and the signing of Laszlo Kubala in June 1950, who would later go on to score 196 goals in 256 matches, drew larger crowds to the games. The club began to make plans for a new stadium. The building of Camp Nou commenced on 28 March 1954, before a crowd of 60,000 Barca fans. The first stone of the future stadium was laid in place under the auspices of Governor Felipe Acedo Colunga and with the blessing of Archbishop of Barcelona Gregorio Modrego. Construction took three years and ended on 24 September 1957 with a final cost of 288 million pesetas, 336% over budget.

When did Barcelona sign Kubala?
Output:
June 1950
