Input: Nintendo Entertainment System
Near the end of the NES's lifespan, upon the release of the AV Famicom and the top-loading NES 2, the design of the game controllers was modified slightly. Though the original button layout was retained, the redesigned device abandoned the brick shell in favor of a dog bone shape. In addition, the AV Famicom joined its international counterpart and dropped the hardwired controllers in favor of detachable controller ports. However, the controllers included with the Famicom AV had cables which were 90 cm (3 feet) long, as opposed to the standard 180 cm(6 feet) of NES controllers.

the original design of the controller was what shape?
Output: brick

Input: Appalachian Mountains
Animals that characterize the Appalachian forests include five species of tree squirrels. The most commonly seen is the low to moderate elevation eastern gray squirrel (Sciurus carolinensis). Occupying similar habitat is the slightly larger fox squirrel (Sciurus niger) and the much smaller southern flying squirrel (Glaucomys volans). More characteristic of cooler northern and high elevation habitat is the red squirrel (Tamiasciurus hudsonicus), whereas the Appalachian northern flying squirrel (Glaucomys sabrinus fuscus), which closely resembles the southern flying squirrel, is confined to northern hardwood and spruce-fir forests.

What is the most commonly seen species?
Output: gray squirrel

Input: Madrasa
There is disagreement whether madaris ever became universities. Scholars like Arnold H. Green and Seyyed Hossein Nasr have argued that starting in the 10th century, some medieval Islamic madaris indeed became universities. George Makdisi and others, however, argue that the European university has no parallel in the medieval Islamic world. Darleen Pryds questions this view, pointing out that madaris and European universities in the Mediterranean region shared similar foundations by princely patrons and were intended to provide loyal administrators to further the rulers' agenda. Other scholars regard the university as uniquely European in origin and characteristics.

What class of people founded both European universities and Islamic madaris
Output: princely patrons

Input: Eton College
Until 18 December 2010, Eton College was an exempt charity under English law (Charities Act 1993, Schedule 2). Under the provisions of the Charities Act 2006, it is now an excepted charity, and fully registered with the Charities Commission, and is now one of the 100 largest charities in the UK. As a charity, it benefits from substantial tax breaks. It was calculated by the late David Jewell, former Master of Haileybury, that in 1992 such tax breaks saved the School about £1,945 per pupil per year, although he had no direct connection with the School. This subsidy has declined since the 2001 abolition by the Labour Government of state-funded scholarships (formerly known as "assisted places") to independent schools. However, no child attended Eton on this scheme, meaning that the actual level of state assistance to the School has always been lower. Eton's retiring Head Master, Tony Little, has claimed that the benefits that Eton provides to the local community free of charge (use of its facilities, etc.) have a higher value than the tax breaks it receives as a result of its charitable status. The fee for the academic year 2010–2011 was £29,862 (approximately US$48,600 or €35,100 as of March 2011), although the sum is considerably lower for those pupils on bursaries and scholarships.

Why is being a charity beneficial to Eton?
Output:
substantial tax breaks
