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.

Passage: Drake ended his studies at Cambridge nine months before graduation, and in autumn 1969 moved to London. His father remembered "writing him long letters, pointing out the disadvantages of going away from Cambridge ... a degree was a safety net, if you manage to get a degree, at least you have something to fall back on; his reply to that was that a safety net was the one thing he did not want." Drake spent his first few months in London drifting from place to place, occasionally staying at his sister's Kensington flat but usually sleeping on friends' sofas and floors. Eventually, in an attempt to bring some stability and a telephone into Drake's life, Boyd organised and paid for a ground floor bedsit in Belsize Park, Camden.
On 5 August 1969, Drake recorded five songs for the BBC's John Peel show ("Cello Song", "Three Hours", "River Man", "Time of No Reply" and an early version of "Bryter Layter"), three of which were broadcast on the following night. A month later, on 24 September, he opened for Fairport Convention at the Royal Festival Hall in London, followed by appearances at folk clubs in Birmingham and Hull. Folk singer Michael Chapman said of the performances:The folkies did not take to him; [they] wanted songs with choruses. They completely missed the point. He didn't say a word the entire evening. It was actually quite painful to watch. I don't know what the audience expected, I mean, they must have known they weren't going to get sea-shanties and sing-alongs at a Nick Drake gig!
The experience reinforced Drake's decision to retreat from live appearances; the few concerts he did play around this time were usually brief, awkward, and poorly attended. Drake seemed reluctant to perform and rarely addressed his audience. As many of his songs were played in different tunings, he frequently paused to retune between numbers.

Ex Output:
Where did the man who did not like to play in front of live audiences end his studies?

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 Output:
Who is Neil Broderick writing a book about?

Passage: Following the release of The Final Cut, Waters embarked on a solo career. In 1984, he released his first solo album, The Pros and Cons of Hitch Hiking, a project about a man's dreams across one night that dealt with Waters' feelings about monogamy and family life versus "the call of the wild". In the end the character, Reg, chooses love and matrimony over promiscuity. The album featured guitarist Eric Clapton, jazz saxophonist David Sanborn, and artwork by Gerald Scarfe. Kurt Loder described The Pros And Cons of Hitch Hiking as a "strangely static, faintly hideous record". Rolling Stone rated the album a "rock bottom one star". Years later, Mike DeGagne of AllMusic praised the album for its "ingenious symbolism" and "brilliant use of stream of consciousness within a subconscious realm", rating it four out of five stars.Waters began touring in support of the album, aided by Clapton, a new band, new material, and a selection of Pink Floyd favourites. Waters debuted his tour in Stockholm on 16 June 1984. The tour suffered from poor ticket sales and some performances at larger venues were cancelled; Waters estimated that he lost 400,000 on the tour. In March 1985, Waters went to North America to play smaller venues with the Pros and Cons Plus Some Old Pink Floyd StuffNorth America Tour 1985. The Pros and Cons of Hitch Hiking has been certified Gold by the RIAA.In 1986, Waters contributed songs and a score to the soundtrack of the animated movie When the Wind Blows, based on the Raymond Briggs book of the same name. His backing band featuring Paul Carrack was credited as The Bleeding Heart Band. In 1987, Waters released Radio K.A.O.S., a concept album based on a mute man named Billy from an impoverished Welsh mining town who has the ability to physically tune into radio waves in his head. Billy first learns to communicate with a radio DJ, and eventually to control the world's computers. Angry at the state of the world in which he lives, he simulates a nuclear attack. Waters followed the release with a supporting tour also in 1987.
