Input: Read this: Yale's residential college system was established in 1933 by Edward S. Harkness, who admired the social intimacy of Oxford and Cambridge and donated significant funds to found similar colleges at Yale and Harvard. Though Yale's colleges resemble their English precursors organizationally and architecturally, they are dependent entities of Yale College and have limited autonomy. The colleges are led by a master and an academic dean, who reside in the college, and university faculty and affiliates comprise each college's fellowship. Colleges offer their own seminars, social events, and speaking engagements known as "Master's Teas," but do not contain programs of study or academic departments. Instead, all undergraduate courses are taught by the Faculty of Arts and Sciences and are open to members of any college.
Question: Who teaches Yale's residential college's undergraduate classes?

Output: Faculty of Arts and Sciences


Input: Read this: In December 1994, after being tipped off by his former FBI handler about a pending indictment under the Racketeer Influenced and Corrupt Organizations Act, Bulger fled Boston and went into hiding. For 16 years, he remained at large. For 12 of those years, Bulger was prominently listed on the FBI Ten Most Wanted Fugitives list. Beginning in 1997, the New England media exposed criminal actions by federal, state, and local law enforcement officials tied to Bulger. The revelation caused great embarrassment to the FBI. In 2002, Special Agent John J Connolly was convicted of federal racketeering charges for helping Bulger avoid arrest. In 2008, Special Agent Connolly completed his term on the federal charges and was transferred to Florida where he was convicted of helping plan the murder of John B Callahan, a Bulger rival. In 2014, that conviction was overturned on a technicality. Connolly was the agent leading the investigation of Bulger.
Question: Whose murder did John B Callahan help to plan?

Output: unanswerable


Input: Read this: The mantle is equivalent to 10 to 15 Earth masses and is rich in water, ammonia and methane. As is customary in planetary science, this mixture is referred to as icy even though it is a hot, dense fluid. This fluid, which has a high electrical conductivity, is sometimes called a water–ammonia ocean. The mantle may consist of a layer of ionic water in which the water molecules break down into a soup of hydrogen and oxygen ions, and deeper down superionic water in which the oxygen crystallises but the hydrogen ions float around freely within the oxygen lattice. At a depth of 7000 km, the conditions may be such that methane decomposes into diamond crystals that rain downwards like hailstones. Very-high-pressure experiments at the Lawrence Livermore National Laboratory suggest that the base of the mantle may comprise an ocean of liquid carbon with floating solid 'diamonds'.
Question: What does the fluid in Neptune have a high conductivity of? 

Output: electrical


Input: Read this: The "orange peel" effect on vinyl records is caused by worn molds. Rather than having the proper mirror-like finish, the surface of the record will have a texture that looks like orange peel. This introduces noise into the record, particularly in the lower frequency range. With direct metal mastering (DMM), the master disc is cut on a copper-coated disc, which can also have a minor "orange peel" effect on the disc itself. As this "orange peel" originates in the master rather than being introduced in the pressing stage, there is no ill effect as there is no physical distortion of the groove.
Question: What material is on a direct metal mastering disc?

Output:
copper
