Input: Gramophone record
The earliest disc records (18891894) were made of various materials including hard rubber. Around 1895, a shellac-based compound was introduced and became standard. Exact formulas for this compound varied by manufacturer and over the course of time, but it was typically composed of about one-third shellac and about two-thirds mineral filler, which meant finely pulverized rock, usually slate and limestone, with an admixture of cotton fibers to add tensile strength, carbon black for color (without this, it tended to be a "dirty" gray or brown color that most record companies considered unattractive), and a very small amount of a lubricant to facilitate mold release during manufacture. Some makers, notably Columbia Records, used a laminated construction with a core disc of coarser material or fiber. The production of shellac records continued until the end of the 78 rpm format (i.e., the late 1950s in most developed countries, but well into the 1960s in some other places), but increasingly less abrasive formulations were used during its declining years and very late examples in truly like-new condition can have as low noise levels as vinyl.

What was the standard material for discs around 1895?
Output: a shellac-based compound

Input: Alexander Graham Bell
Returning home to Brantford after six months abroad, Bell continued his experiments with his "harmonic telegraph".[N 12] The basic concept behind his device was that messages could be sent through a single wire if each message was transmitted at a different pitch, but work on both the transmitter and receiver was needed.

Where was Bell's home?
Output: Brantford

Input: Premier League
The managing director of London Weekend Television (LWT), Greg Dyke, met with the representatives of the "big five" football clubs in England in 1990. The meeting was to pave the way for a break away from The Football League. Dyke believed that it would be more lucrative for LWT if only the larger clubs in the country were featured on national television and wanted to establish whether the clubs would be interested in a larger share of television rights money. The five clubs decided it was a good idea and decided to press ahead with it; however, the league would have no credibility without the backing of The Football Association and so David Dein of Arsenal held talks to see whether the FA were receptive to the idea. The FA did not enjoy an amicable relationship with the Football League at the time and considered it as a way to weaken the Football League's position.

Why did Dyke only want the larger clubs featured on national television?
Output: Dyke believed that it would be more lucrative for LWT if only the larger clubs in the country were featured on national television

Input: Federal Bureau of Investigation
Beginning in the 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed (Ex parte Quirin) under their sentences. Also during this time, a joint US/UK code-breaking effort (the Venona project)with which the FBI was heavily involvedbroke Soviet diplomatic and intelligence communications codes, allowing the US and British governments to read Soviet communications. This effort confirmed the existence of Americans working in the United States for Soviet intelligence. Hoover was administering this project but failed to notify the Central Intelligence Agency (CIA) until 1952. Another notable case is the arrest of Soviet spy Rudolf Abel in 1957. The discovery of Soviet spies operating in the US allowed Hoover to pursue his longstanding obsession with the threat he perceived from the American Left, ranging from Communist Party of the United States of America (CPUSA) union organizers to American liberals.

What agency did Hoover not tell about the code break and the discoveries gained from it?
Output:
CIA
