Q: 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 theorythat 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?

A: Heseltine.

Q: Passage: En route to California to prospect for gold, ex-sheriff Hooker, professional gambler Fiske, and bounty hunter Luke Daly are forced to stop over in a tiny Mexican village by engine trouble on the ship they are taking. A desperate Leah Fuller hires the three men and local Vicente Madariaga, to rescue her husband, John, who is pinned under debris from a gold mine cave-in in hostile Apache territory.
During the harrowing journey, Luke tries to force himself on Leah late one night, forcing Hooker to intervene. Leah tells Hooker that where her husband is trapped, once was a boom town, but a volcano eruption wiped it out, leaving only a church steeple and the mine uncovered by lava. The resident priest called it the "garden of evil". The Indians now consider the volcano sacred. The group then arrives at the mine. They find John unconscious, and they free him.
Before John wakes up, Hooker sets the man's broken leg. When John regains consciousness, he accuses Leah of using him to get gold. Hooker talks to Leah later, about what her husband said; after he tells her that he has spotted signs of Apaches nearby, she offers him and the others all the gold they have dug up to take her husband away that night, while she remains behind to make it look like they are all still there. The cynical Fiske unexpectedly offers to stay with her, but when he asks her what he is to her, she tells him, "you're nothing at all, just nothing.".
Question: What is the last name of the person John accuses of using him?

A: Fuller.

Q: Passage: Minnesota has four ecological provinces: Prairie Parkland, in the southwestern and western parts of the state; the Eastern Broadleaf Forest (Big Woods) in the southeast, extending in a narrowing strip to the state's northwestern part, where it transitions into Tallgrass Aspen Parkland; and the northern Laurentian Mixed Forest, a transitional forest between the northern boreal forest and the broadleaf forests to the south. These northern forests are a vast wilderness of pine and spruce trees mixed with patchy stands of birch and poplar.
Much of Minnesota's northern forest underwent logging at some time, leaving only a few patches of old growth forest today in areas such as in the Chippewa National Forest and the Superior National Forest, where the Boundary Waters Canoe Area Wilderness has some 400,000 acres (162,000 ha) of unlogged land. Although logging continues, regrowth and replanting keep about one third of the state forested. Nearly all of Minnesota's prairies and oak savannas have been fragmented by farming, grazing, logging, and suburban development.While loss of habitat has affected native animals such as the pine marten, elk, woodland caribou, and bison, others like whitetail deer and bobcat thrive. The state has the nation's largest population of timber wolves outside Alaska, and supports healthy populations of black bears, moose, and gophers. Located on the Mississippi Flyway, Minnesota hosts migratory waterfowl such as geese and ducks, and game birds such as grouse, pheasants, and turkeys. It is home to birds of prey, including the largest number of breeding pairs of bald eagles in the lower 48 states, as of 2007, red-tailed hawks, and snowy owls. The lakes teem with sport fish such as walleye, bass, muskellunge, and northern pike, and streams in the southeast and northeast are populated by brook, brown, and rainbow trout.
Question: What are the exact names of the four distinct ecological provinces in Minnesota?

A:
Prairie Parkland.
