input: A rapid series of rhythmic and harmonic changes introduces a pseudo-operatic midsection, which contains the bulk of the elaborate vocal multi-tracking, depicting the narrator's descent into hell. While the underlying pulse of the song is maintained, the dynamics vary greatly from bar to bar, from only Mercury's voice accompanied by a piano to a multi-voice choir supported by drums, bass, piano and Timpani. The choir effect was created by having May, Mercury, and Taylor repeatedly sing their vocal parts, resulting in 180 separate overdubs. These overdubs were then combined into successive submixes. According to Roger Taylor, the voices of May, Mercury and himself combined created a wide vocal range: "Brian could get down quite low, Freddie had a powerful voice through the middle, and I was good at the high stuff." The band wanted to create "a wall of sound, that starts down and goes all the way up". The band used the bell effect for lyrics "Magnifico" and "Let me go". Also, on "Let him go", Taylor singing the top section carries his note on further after the rest of the "choir" have stopped singing. Lyrical references in this passage include Scaramouche, the fandango, Galileo Galilei, Figaro, Beelzebub and Bismillah, as rival factions fight over the narrator's soul. The section concludes with a full choral treatment of the lyric "Beelzebub has a devil put aside for me!", on a block B major chord. Roger Taylor tops the final chord with a falsetto B in the fifth octave (B5). Using the 24-track technology available at the time, the "opera" section took about three weeks to finish. Producer Roy Thomas Baker said "Every time Freddie came up with another 'Galileo', I would add another piece of tape to the reel." Baker recalls that they kept wearing out the tape, which meant having to do transfers.

input: Ma He was captured by the Ming armies at Yunnan in 1381. General Fu Youde saw Ma He on a road and approached him in order to inquire about the location of the Mongol pretender. Ma He responded defiantly by saying that the Mongol pretender had jumped into a lake. Afterwards, the general took him prisoner. He was castrated before being placed in servitude of the Prince of Yan at age 10, although another source indicates the castration occurred in 1385. Ma was sent to serve in the household of Zhu Di, the Prince of Yan, who later became the Yongle Emperor. Zhu Di was eleven years older than Ma. Since 1380, the prince had been governing Beiping (later Beijing), which was located near the northern frontier where the hostile Mongol tribes were situated. Ma would spend his early life as a soldier on the northern frontier. He often participated in Zhu Di's military campaigns against the Mongols. On 2 March 1390, Ma accompanied the Prince when he commanded his first expedition, which was a great victory as the Mongol commander Naghachu surrendered as soon as he realized he had fallen for a deception. Eventually, he would gain the confidence and trust of the prince. Ma was also known as "san bao" during the time of service in the household of the Prince of Yan. This name was a reference to the Three Jewels (San Bao , triratna) in Buddhism. There is also document saying his name could be San Bao (lit. "Three Protections", also pronounced san bao). Ma received a proper education while at Beiping, which he would not have had if he had been placed in the imperial capital Nanjing, as the Hongwu Emperor did not trust eunuchs and believed that it was better to keep them illiterate. Meanwhile, the Hongwu Emperor purged and exterminated many of the original Ming leadership and gave his enfeoffed sons more military authority, especially those in the north like the Prince of Yan.

Answer this question "Did he have any children?"
output: the castration occurred in 1385.

input: In 1966, thanks to his friendship with Hansgen, word quickly spread to the Ford Motor Company about the young driver. Ford immediately signed Donohue to drive one of their GT-40 Mk II race cars campaigned at the 24 Hours of Le Mans by the Holman & Moody racing team. Le Mans proved frustrating for Donohue. Hansgen died while testing the GT40 in preparation for Le Mans so Donohue partnered with Australian Paul Hawkins. Donohue and Hawkins only completed twelve laps due to differential failure and finished 47th. Earlier that year, co-driving with Hansgen, Donohue finished third at the 24 Hours of Daytona and second at the 12 Hours of Sebring. At Hansgen's funeral, Roger Penske spoke to Donohue about driving for him. In his first race for Penske, at Watkins Glen in June 1966, Donohue qualified well but crashed the car at the top of a hill, destroying it. Donohue was invited back to Le Mans by Ford in 1967. Ford had developed a new GT, the Mark IV. Donohue co-drove in the No. 4 yellow car with sports car driver and race car builder Bruce McLaren for Shelby American Racing. The two drivers disagreed on many aspects of racing and car setup, but as a team were able to muster a fourth-place finish in the endurance classic. In 1967, Penske contacted Donohue about driving Penske's brand new Lola T70 spyder in the United States Road Racing Championship. Donohue dominated the 1967 race, driving a Lola T70 MkIII Chevrolet for Penske. Donohue raced in seven of the eight races that year, winning six (at Las Vegas, Riverside, Bridgehampton, Watkins Glen, Pacific Raceways, and Mid-Ohio) and finishing third at the Laguna Seca Raceway round behind Lothar Motschenbacher and Mike Goth. In 1968, Donohue and Penske returned to defend their USRRC championship with the McLaren M6A Chevrolet. Donohue did not start the first race of the year at Circuit Hermanos Rodriguez in Mexico City due to problems getting the engine to start. Despite this, Donohue still dominated the series, even though he suffered three DNFs during the season due to mechanical problems with the M6A.
