Input: The Bronx
The northern side of the borough includes the largest park in New York CityPelham Bay Park, which includes Orchard Beachand the fourth largest, Van Cortlandt Park, which is west of Woodlawn Cemetery and borders Yonkers. Also in the northern Bronx, Wave Hill, the former estate of George W. Perkinsknown for a historic house, gardens, changing site-specific art installations and concertsoverlooks the New Jersey Palisades from a promontory on the Hudson in Riverdale. Nearer the borough's center, and along the Bronx River, is Bronx Park; its northern end houses the New York Botanical Gardens, which preserve the last patch of the original hemlock forest that once covered the entire county, and its southern end the Bronx Zoo, the largest urban zoological gardens in the United States. Just south of Van Cortlandt Park is the Jerome Park Reservoir, surrounded by 2 miles (3 km) of stone walls and bordering several small parks in the Bedford Park neighborhood; the reservoir was built in the 1890s on the site of the former Jerome Park Racetrack. Further south is Crotona Park, home to a 3.3-acre (1.3 ha) lake, 28 species of trees, and a large swimming pool. The land for these parks, and many others, was bought by New York City in 1888, while land was still open and inexpensive, in anticipation of future needs and future pressures for development.

When was the Jerome Park Reservoir built?
Output: in the 1890s

Input: Dissolution of the Soviet Union
Following the hardliners' takeover, the September 30, 1990 elections (runoffs on October 14) were characterized by intimidation; several Popular Front candidates were jailed, two were murdered, and unabashed ballot stuffing took place even in the presence of Western observers. The election results reflected the threatening environment; out of the 350 members, 280 were Communists, with only 45 opposition candidates from the Popular Front and other non-communist groups, who together formed a Democratic Bloc ("Dembloc"). In May 1990 Mutalibov was elected Chairman of the Supreme Soviet unopposed.

What party's candidates were murdered in the September 30 elections?

Input: Gramophone record
The lateral cut NAB curve was remarkably similar to the NBC Orthacoustic curve that evolved from practices within the National Broadcasting Company since the mid-1930s. Empirically, and not by any formula, it was learned that the bass end of the audio spectrum below 100 Hz could be boosted somewhat to override system hum and turntable rumble noises. Likewise at the treble end beginning at 1,000 Hz, if audio frequencies were boosted by 16 dB at 10,000 Hz the delicate sibilant sounds of speech and high overtones of musical instruments could survive the noise level of cellulose acetate, lacquer/aluminum, and vinyl disc media. When the record was played back using a complementary inverse curve, signal-to-noise ratio was improved and the programming sounded more lifelike.

What bass settings were needed to eliminate hum?
Output: below 100 Hz
