instruction:
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
question:
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.".
answer:
What are the full names of the two people that travel with the ex-sheriff?

Passage: In London, Grainger's charm, good looks and talent (with some assistance from the local Australian community) ensured that he was quickly taken up as a pianist by wealthy patrons. He was soon performing in concerts in private homes. The Times critic reported after one such appearance that Grainger's playing "revealed rare intelligence and a good deal of artistic insight".  In 1902 he was presented by the socialite Lillith Lowrey to Queen Alexandra, who thereafter frequently attended his London recitals. Lowrey, 20 years Grainger's senior, traded patronage and contacts for sexual favours – he termed the relationship a "love-serve job". She was the first woman with whom he had sex; he later wrote of this initial encounter that he had experienced "an overpowering landslide" of feeling, and that "I thought I was about to die. If I remember correctly, I only experienced fear of death. I don't think that any joy entered into it".In February 1902 Grainger made his first appearance as a piano soloist with an orchestra, playing Tchaikovsky's first piano concerto with the Bath Pump Room Orchestra. In October of that year he toured Britain in a concert party with Adelina Patti, the Italian-born opera singer. Patti was greatly taken by the young pianist and prophesied a glorious career for him. The following year he met the German-Italian composer and pianist Ferruccio Busoni. Initially the two men were on cordial terms (Busoni offered to give Grainger lessons free of charge) and, as a result, Grainger spent part of the 1903 summer in Berlin as Busoni's pupil.  However, the visit was not a success; as Bird notes, Busoni had expected "a willing slave and adoring disciple", a role Grainger was not willing to fulfill. Grainger returned to London in July 1903; almost immediately he departed with Rose on a 10-month tour of Australia, New Zealand and South Africa, as a member of a party organised by the Australian contralto Ada Crossley.
answer:
What is the full name of the person that Grainger was presented to?


question:
Passage: A man unveils a valuable painting he picked up for $50,000 and is killed. A card with a large black ace (of spades) is put on his chest. Another "Black Ace" victim. The killer sends his victims a Black Ace card, warning them they are to die and then kills them, his way of taunting the police. Neil Broderick, an author, intends writing a book about him and is on his way to see Thornton Drake to get more information about him. Austin Winters is his secretary and Neil met his daughter Martha on the train, on the way to Chicago.
Drake has just received a Black Ace, with the words: "At seven tomorrow night", the time he is to be killed. Two plainclothes cops arrive from police headquarters, having had a call, Clancy and Dugan (both incompetents). Martha suggests that they leave for Drake's Louisiana plantation tomorrow morning and be far away from there at seven tomorrow night. Drake agrees and suggests they all go. On the flight, the lights go off for some seconds and when they come on again, Austin Winters is dead without a mark on him.
At the plantation, Clancy ineptly questions the suspects till Neil points out that they are now in another state, so out of their jurisdiction. Neil goes to another room and makes a phone call, then signals to someone outside. After he finishes his call, the line is cut. Meanwhile one of the pilots has taken off in the plane, leaving the other pilot, Henderson, behind who claims he does not know anything though he was out of the cockpit when Winters was killed.
The coroner finds a letter on the dead man which is to be read if Winters dies. It will reveal the identity of the Black Ace. Clancy starts reading it aloud and unsurprisingly the lights go off and the letter has vanished when the lights are turned on again. People locked in their rooms that night and Neil has a hidden car outside signal to him.
answer:
Who is Neil Broderick writing a book about?
