Example Input: Question: What year was the university Lawrence Lessig taught at founded? Passage:Remix culture, sometimes read-write culture, is a society that allows and encourages derivative works by combining or editing existing materials to produce a new creative work or product. A remix culture would be, by default, permissive of efforts to improve upon, change, integrate, or otherwise remix the work of copyright holders. While a common practice of artists of all domains throughout human history, the growth of exclusive copyright restrictions in the last several decades limits this practice more and more by the legal chilling effect. In reaction, Harvard law professor Lawrence Lessig who considers remixing a desirable concept for human creativity has worked since the early 2000s on a transfer of the remixing concept into the digital age. Lessig founded the Creative Commons in 2001 which released Licenses as tools to enable remix culture again, as remixing is legally prevented by the default exclusive copyright regime applied currently on intellectual property. The remix culture for cultural works is related to and inspired by the earlier Free and open-source software for software movement, which encourages the reuse and remixing of software works.
