In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Input: Consider Input: Question: On what date did Apollo 11 land at it's destination site? Passage: are three views of Mare Tranquillitatis on the Moon, taken by the mapping camera of the Apollo 17 mission in 1972, facing south-southwest from an average altitude of 111km on Revolution 36 of the mission. At the left is the east side of Mare Tranquillitatis, with the craters Franz (bottom right), Lyell (dark floor, right of center), and Taruntius (upper left). The "bay" of dark mare (basalt) at left is Sinus Concordiae, with "islands" of older, light highland material. At the right is the crater Cauchy, which lies between the Rupes Cauchy and Cauchy rille. The center photo shows the central mare with craters Vitruvius (lower right) and Gardner (bottom center). At the horizon are lighter highlands at the southern margin of the mare, near the Apollo 11 landing site. The crater Jansen is visible at the edges of both the center and right photos. The right photo shows the western mare, with the craters Dawes (lower left) and the large Plinius (43km diameter), with the Plinius Rilles in the foreground. These photos were taken within minutes of each other as the command module America orbited the Moon. The Sun elevation drops from 46 degrees at left to 30 degrees at right.

Input: Consider Input: Question: How long has the location at the fish's southernmost range been a country? Passage:The cocinero (Caranx vinctus), also known as the barred jack and striped jack, is a species of small marine fish classified in the jack family, Carangidae. The cocinero is distributed through the tropical eastern Pacific Ocean, ranging along the west American coastline from Baja California in the north to Peru in the south. It is a pelagic species, inhabiting the upper water column in both coastal and offshore oceanic waters, occasionally making its way into estuaries. The species may be identified by its colouration, having 8 or 9 incomplete dark vertical stripes on its sides, with scute and gill raker counts also diagnostic. It is small compared to most other species of Caranx, reaching a length of 37cm in total. The cocinero is a predatory fish, taking small fishes, crustaceans, and various benthic invertebrates in shallower waters. Little is known of the species' reproductive habits. The cocinero is of moderate importance to fisheries along the west coast of South America, and the species has been used in aquaculture trials. It is taken by various netting methods and by spear, and is sold fresh, dried, and salted at market.

Input: Consider 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.
