Input: Article: Mach suggested that thought experiments like the bucket argument are problematic. If we were to imagine a universe that only contains a bucket, on Newton's account, this bucket could be set to spin relative to absolute space, and the water it contained would form the characteristic concave surface. But in the absence of anything else in the universe, it would be difficult to confirm that the bucket was indeed spinning. It seems equally possible that the surface of the water in the bucket would remain flat.

Now answer this question: What is difficult to confirm about the bucket in the absence of anything else in the universe?

Output: that the bucket was indeed spinning

Input: Article: In January 1938, Milt Gabler started recording for his new label, Commodore Records, and to allow for longer continuous performances, he recorded some 12-inch records. Eddie Condon explained: "Gabler realized that a jam session needs room for development." The first two 12-inch recordings did not take advantage of the extra length: "Carnegie Drag" was 3:15; "Carnegie Jump", 2:41. But at the second session, on April 30, the two 12-inch recordings were longer: "Embraceable You" was 4:05; "Serenade to a Shylock", 4:32. Another way around the time limitation was to issue a selection on both sides of a single record. Vaudeville stars Gallagher and Shean recorded "Mr. Gallagher and Mr. Shean", written by Irving and Jack Kaufman, as two sides of a 10-inch 78 in 1922 for Cameo. An obvious workaround for longer recordings was to release a set of records. An early multi-record release was in 1903, when HMV in England made the first complete recording of an opera, Verdi's Ernani, on 40 single-sided discs. In 1940, Commodore released Eddie Condon and his Band's recording of "A Good Man Is Hard to Find" in four parts, issued on both sides of two 12-inch 78s. This limitation on the duration of recordings persisted from 1910 until the invention of the LP record, in 1948. In popular music, this time limitation of about 3:30 on a 10-inch 78 rpm record meant that singers usually did not release long pieces on record. One exception is Frank Sinatra's recording of Rodgers and Hammerstein's "Soliloquy", from Carousel, made on May 28, 1946. Because it ran 7:57, longer than both sides of a standard 78 rpm 10-inch record, it was released on Columbia's Masterwork label (the classical division) as two sides of a 12-inch record. The same was true of John Raitt's performance of the song on the original cast album of Carousel, which had been issued on a 78-rpm album set by American Decca in 1945.

Now answer this question: On which label did Frank Sinatra release his recording of Soliloquy?

Output: Columbia's Masterwork label

Input: Article: In 1970, the New Haven Black Panther trials took place, the largest and longest trials in Connecticut history. Black Panther Party co-founder Bobby Seale and ten other Party members were tried for murdering an alleged informant. Beginning on May Day, the city became a center of protest for 12,000 Panther supporters, college students, and New Left activists (including Jean Genet, Benjamin Spock, Abbie Hoffman, Jerry Rubin, and John Froines), who amassed on the New Haven Green, across the street from where the trials were being held. Violent confrontations between the demonstrators and the New Haven police occurred, and several bombs were set off in the area by radicals. The event became a rallying point for the New Left and critics of the Nixon Administration.

Now answer this question: What was the name of one of the party's leader that also happen to be on trial?

Output:
Bobby Seale
