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.

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


[Q]: Passage: The party turned for home after 73 days' southward travel. Rations had been cut several times to extend the return journey time beyond the original 110-day estimate. Shackleton now aimed to reach Hut Point in 50 days, since according to Shackleton's prior orders Nimrod, having returned to take the expedition home, would depart on 1 March at the latest. The four men were now much weakened, yet in the following days they achieved impressive distances, reaching the head of the glacier on 19 January. As they began the descent they had five days' food at half rations, to last them until the Lower Glacier depot; during the ascent the same distance had taken 12 days. Shackleton's physical condition was by now a major concern, yet according to Adams "the worse he felt, the harder he pulled".The depot was reached on 28 January. Wild, ill with dysentery, was unable to pull or to eat anything but biscuits, which were in short supply. On 31 January Shackleton forced his own breakfast biscuit on Wild, a gesture that moved Wild to write: "BY GOD I shall never forget. Thousands of pounds would not have bought that one biscuit". A few days later, the rest of the party were struck with severe enteritis, the result of eating tainted pony-meat. But the pace of march had to be maintained; the small amounts of food carried between depots would make any delay fatal. However, a strong wind behind them enabled them to set a sail on the sledge and maintain a good marching rate.
"We are so thin that our bones ache as we lie on the hard snow", wrote Shackleton. From 18 February onward they began to pick up familiar landmarks, and on the 23rd they reached Bluff Depot, which to their great relief had been copiously resupplied by Ernest Joyce. The range of delicacies over and above the crates of regular supplies was listed by Shackleton: "Carlsbad plums, eggs, cakes, plum pudding, gingerbread and crystallised fruit". Wild's laconic comment was "Good old Joyce".Their food worries were now resolved, but they still had to get back to Hut Point before the 1 March deadline. The final leg of their march was interrupted by a blizzard, which held them in camp for 24 hours. On 27 February, when they were still 33 nautical miles (61 km; 38 mi) from safety, Marshall collapsed. Shackleton then decided that he and Wild would make a dash for Hut Point in hopes of finding the ship and holding her until the other two could be rescued. They reached the hut late on 28 February. Hoping that the ship was nearby, they sought to attract its attention by setting fire to a small wooden hut used for magnetic observations. Shortly afterwards Nimrod, which had been anchored at the Glacier Tongue, came into view: "No happier sight ever met the eyes of man", wrote Wild later. It was a further three days before Adams and Marshall could be picked up from the Barrier, but by 4 March the whole southern party was aboard and Shackleton was able to order full steam towards the north.
[A]: What is the first name of "Good old Joyce?"?


[Q]: Passage: In June 2006, talks concerning a territorial dispute over the Bakassi peninsula were resolved. The talks involved President Paul Biya of Cameroon, then President Olusegun Obasanjo of Nigeria and then UN Secretary General Kofi Annan, and resulted in Cameroonian control of the oil-rich peninsula. The northern portion of the territory was formally handed over to the Cameroonian government in August 2006, and the remainder of the peninsula was left to Cameroon 2 years later, in 2008. The boundary change was met with a local insurgency, as some Bakassians preferred to remain Nigerian. Most militants laid down their arms in November 2009.In February 2008, Cameroon experienced its worst violence in 15 years when a transport union strike in Douala escalated into violent protests in 31 municipal areas.In May 2014, in the wake of the Chibok schoolgirl kidnapping, presidents Paul Biya of Cameroon and Idriss Déby of Chad announced they are waging war on Boko Haram, and deployed troops to the Nigerian border.Since November 2016, protesters from the predominantly English-speaking Northwest and Southwest regions of the country have been campaigning for continued use of the English language in schools and courts. People were killed and hundreds jailed as a result of these protests. In 2017, Biya's government blocked the regions' access to the Internet for three months. In September, separatists started a guerilla war for the indendence of the Anglophone region as the Federal Republic of Ambazonia. The government responded with a military offensive, and the insurgency spread across the Northwest and Southwest regions. As of 2019, fighting between separatist guerillas and government forces continues. The conflict indirectly led to an upsurge in Boko Haram activities, as the Cameroonian military largely withdrew from the north to focus on fighting the Ambazonian separatists.
[A]:
What were the full names of the people who were involved in the talks concerning a territorial dispute over the Bakassi peninsula?
