Passage: In September 1930 Heseltine moved with Barbara Peache into a basement flat at 12a Tite Street in Chelsea. With no fresh creative inspiration, he worked in the British Museum to transcribe the music of English composer Cipriani Potter, and made a solo version of "Bethlehem Down" with organ accompaniment. On the evening of 16 December Heseltine met with Van Dieren and his wife for a drink and invited them home afterwards. According to Van Dieren, the visitors left at about 12:15 a.m. Neighbours later reported sounds of movement and of a piano in the early morning. When Peache, who had been away, returned early on 17 December, she found the doors and windows bolted, and smelled coal gas. The police broke into the flat and found Heseltine unconscious; he was declared dead shortly afterwards, apparently as the result of coal gas poisoning.An inquest was held on 22 December; the jury could not determine whether the death was accidental or suicide and an open verdict was returned. Most commentators have considered suicide the more likely cause; Heseltine's close friend Lionel Jellinek and Peache both recalled that he had previously threatened to take his life by gas and the outline of a new will was found among the papers in the flat. Much later, Nigel Heseltine introduced a new theory—that his father had been murdered by Van Dieren, the sole beneficiary of Heseltine's 1920 will, which stood to be revoked by the new one. This theory is not considered tenable by most commentators. The suicide theory is supported (arguably), by the (supposed, accepted) fact that Heseltine/Warlock had put his young cat outside the room before he had turned on the lethal gas.Philip Heseltine was buried alongside his father at Godalming cemetery on 20 December 1930. In late February 1931, a memorial concert of his music was held at the Wigmore Hall; a second such concert took place in the following December.In 2011 the art critic Brian Sewell published his memoirs, in which he claimed that he was Heseltine's illegitimate son, born in July 1931 seven months after the composer's death. Sewell's mother, unnamed, was an intermittent girlfriend, a Roman Catholic  who refused Heseltine's offer to pay for an abortion and subsequently blamed herself for his death. Sewell was unaware of his father's identity until 1986. 
Question: What is the last name of the person whose death could not be determined to be accident or suicide?

Ex Output:
Heseltine.

Passage: Half of Minneapolis–Saint Paul residents work in the city where they live. Most residents drive cars, but 60% of the 160,000 people working downtown commute by means other than a single person per auto. The Metropolitan Council's Metro Transit, which operates the light rail system and most of the city's buses, provides free travel vouchers through the Guaranteed Ride Home program to allay fears that commuters might otherwise be occasionally stranded if, for example, they work late hours.On January 1, 2011, the city's limit of 343 taxis was lifted.Minneapolis currently has two light rail lines and one commuter rail line. The METRO Blue Line LRT (formerly the Hiawatha Line) serves 34,000 riders daily and connects the Minneapolis–Saint Paul International Airport and Mall of America in Bloomington to downtown. Most of the line runs at surface level, although parts of the line run on elevated tracks (including the Franklin Avenue and Lake Street/Midtown stations) and approximately 2 miles (3.2 km) of the line runs underground, including the Lindbergh terminal subway station at the airport. 
Question: What is the former name of the line that has a terminal subway station at the airport?

Ex Output:
Hiawatha Line.

Passage: The passage is obscure, but Cerutti and Richardson argue that Gracchus begins the fight as a loincloth-wearing retiarius. When the tide turns against him, he dons a tunic and a womanish wig (spira), apparently part of the same costume, and thus enjoys a reprieve, although this attire may not itself have been considered effeminate as it was also worn by the priests of Mars of whom Gracchus was the chief priest. The change of clothing seems to turn a serious fight into a comical one and shames his opponent. It is unusual to see a gladiator depicted this way in a satire, as such fighters usually take the role of men who are "brawny, brutal, sexually successful with women of both high and low status, but especially the latter, ill-educated if not uneducated, and none too bright intellectually." The retiarius tunicatus in the satire is the opposite: "a mock gladiatorial figure, of equivocal sex, regularly dressed in costume of some sort, possibly usually as a woman, and matched against a secutor or murmillo in a mock gladiatorial exhibition."Despite their low status, some retiarii became quite popular throughout the early Empire. The fact that spectators could see net-fighters' faces humanised them and probably added to their popularity. At Pompeii, graffiti tells of Crescens or Cresces the retiarius, "lord of the girls" and "doctor to nighttime girls, morning girls, and all the rest." Evidence suggests that some homosexual men fancied gladiators, and the retiarius would have been particularly appealing. Roman art depicts net-men just as often as other types. A mosaic found in 2007 in a bathhouse at the Villa dei Quintili shows a retiarius named Montanus. The fact that his name is recorded indicates that the gladiator was famous. The mosaic dates to c. CE 130, when the Quintilii family had the home built; the emperor Commodus, who fought in gladiatorial bouts as a secutor, acquired the house in CE 182 and used it as a country villa. In modern times, popular culture has made the retiarius probably the most famous type of gladiator. 
Question: What is the full name of the home built by the Quintilii family?

Ex Output:

Villa dei Quintili.
