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.

[EX Q]: Passage: In 1990, Zappa was diagnosed with terminal prostate cancer. The disease had been developing unnoticed for ten years and was considered inoperable. After the diagnosis, Zappa devoted most of his energy to modern orchestral and Synclavier works. Shortly before his death in 1993 he completed Civilization Phaze III, a major Synclavier work which he had begun in the 1980s.In 1991, Zappa was chosen to be one of four featured composers at the Frankfurt Festival in 1992 (the others were John Cage, Karlheinz Stockhausen, and Alexander Knaifel). Zappa was approached by the German chamber ensemble Ensemble Modern which was interested in playing his music for the event. Although ill, he invited them to Los Angeles for rehearsals of new compositions and new arrangements of older material. Zappa also got along with the musicians, and the concerts in Germany and Austria were set up for later in the year. Zappa also performed in 1991 in Prague, claiming that "was the first time that he had a reason to play his guitar in 3 years", and that that moment was just "the beginning of a new country", and asked the public to "try to keep your country unique, do not change it into something else".In September 1992, the concerts went ahead as scheduled but Zappa could only appear at two in Frankfurt due to illness. At the first concert, he conducted the opening "Overture", and the final "G-Spot Tornado" as well as the theatrical "Food Gathering in Post-Industrial America, 1992" and "Welcome to the United States" (the remainder of the program was conducted by the ensemble's regular conductor Peter Rundel). Zappa received a 20-minute ovation. G-Spot Tornado was performed with Canadian dancer Louise Lecavalier. It was his last professional public appearance as the cancer was spreading to such an extent that he was in too much pain to enjoy an event that he otherwise found "exhilarating". Recordings from the concerts appeared on The Yellow Shark (1993), Zappa's last release during his lifetime, and some material from studio rehearsals appeared on the posthumous Everything Is Healing Nicely (1999).
[EX A]: In what city was Zappa's last professional public appearance?

[EX Q]: 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.
[EX A]: Who is Neil Broderick writing a book about?

[EX Q]: Passage: The end of Patience Camp was signalled on the evening of 8 April, when the floe suddenly split. The camp now found itself on a small triangular raft of ice; a break-up of this would mean disaster, so Shackleton readied the lifeboats for the party's enforced departure. He had now decided they would try, if possible, to reach the distant Deception Island because a small wooden church had been reportedly erected for the benefit of whalers. This could provide a source of timber that might enable them to construct a seaworthy boat.At 1 p.m. on 9 April, the Dudley Docker was launched, and an hour later all three boats were away. Shackleton himself commanded the James Caird, Worsley the Dudley Docker, and navigating officer Hubert Hudson was nominally in charge of the Stancomb Wills, though because of his precarious mental state the effective commander was Tom Crean.The boats were surrounded by ice, dependent upon leads of water opening up, and progress was perilous and erratic. Frequently the boats were tied to floes, or dragged up onto them, while the men camped and waited for conditions to improve. Shackleton was wavering again between several potential destinations, and on 12 April, rejected the various island options and decided on Hope Bay, at the very tip of Graham Land. However, conditions in the boats, in temperatures sometimes as low as −20 °F (−29 °C), with little food and regular soakings in icy seawater, were wearing the men down, physically and mentally. Shackleton therefore decided that Elephant Island, the nearest of the possible refuges, was now the most practical option.On 14 April, the boats lay off the south-east coast of Elephant Island, but could not land as the shore consisted of perpendicular cliffs and glaciers. Next day the James Caird rounded the eastern point of the island, to reach the northern lee shore, and discovered a narrow shingle beach. Soon afterwards, the three boats, which had been separated during the previous night, were reunited at this landing place. It was apparent from high tide markings that this beach would not serve as a long-term camp, so the next day Wild and a crew set off in the Stancomb Wills to explore the coast for a safer site. They returned with news of a long spit of land, seven miles (11 km) to the west. With minimum delay the men returned to the boats and transferred to this new location, which they later christened Cape Wild.
[EX A]:
What was the full name of the person with a precarious mental state?
