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: 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: In part because he was overlooked until the mid-19th century, Velazquez found no followers and was not widely imitated. In particular, his visual and structural innovations in this portrayal of Venus were not developed by other artists until recently, largely owing to the censorship of the work. The painting remained in a series of private rooms in private collections until it was exhibited in 1857 at the Manchester Art Treasures Exhibition, along with 25 other paintings at least claimed to be by Velazquez; it was here that it became known as the Rokeby Venus. It does not appear to have been copied by other artists, engraved or otherwise reproduced, until this period. In 1890 it was exhibited in the Royal Academy in London, and in 1905 at Messrs. Agnews, the dealers who had bought it from Morritt. From 1906 it was highly visible in the National Gallery and became well-known globally through reproductions. The general influence of the painting was therefore long delayed, although individual artists would have been able to see it on occasion throughout its history.
Velazquez's portrait is a staging of a private moment of intimacy and a dramatic departure from the classical depictions of sleep and intimacy found in works from antiquity and Venetian art that portray Venus. However, the simplicity with which Velazquez displays the female nudewithout jewellery or any of the goddess's usual accessorieswas echoed in later nude studies by Ingres, Manet, and Baudry, among others. In addition, Velazquez's depiction of Venus as a reclining nude viewed from the rear was a rarity before that time, although the pose has been painted by many later artists. Manet, in his stark female portrayal Olympia, paraphrased the Rokeby Venus in pose and by suggesting the persona of a real woman rather than an ethereal goddess. Olympia shocked the Parisian art world when it was first exhibited in 1863. Olympia gazes directly out at the viewer, as does Velazquez's Venus, only through the reflection of the mirror.
[EX A]: What is the title of that which was exhibited at Messrs in 1905??

[EX Q]: Passage: After two more EPs on Kompakt, the Orb (now composed of only Paterson and Fehlmann) released Okie Dokie It's The Orb on Kompakt, which featured new material in addition to tweaked versions of their previous Kompakt output. By this stage, Allmusic observed, Thomas Fehlmann had become the primary creative figure in the Orb, "inhibiting Alex Paterson's whimsical impulses". Because of this, Okie Dokie was considerably more focused and less "goofy" than Cydonia and Bicycles & Tricycles. Fehlmann's trademark hypnotic loops and delays made him the centre of Okie Dokie production and, according to Pitchfork Media, made it "difficult to say where [Paterson] is in the picture". The Orb's releases with Kompakt gained them back much of their musical credibility with the press and showed that they could "age gracefully".In August 2006, the founders of the Orb - Paterson and Cauty - released Living in a Giant Candle Winking at God, their debut album as the Transit Kings with Guy Pratt and Pratt's associate, Dom Beken. The album featured appearances from Smiths' guitarist Johnny Marr and comedian Simon Day. Beken described Living in a Giant Candle Winking at God as "self-consciously musically written and less sample-based" compared to the members' previous work. Living had been in production since 2001, but due to members' other obligations, it was delayed for several years. The album received mixed critical reactions, with reviewers such as The Sun comparing the album favourably to the music of DJ Shadow and Royksopp while other publications, such as The Times, called it "Orb-lite" and proclaimed it to be "Deep Forest-style sludge". Soon after the album's release, Cauty left the Transit Kings on "extended leave", leaving the project in indefinite limbo. Paterson and Beken reunited in 2008 as High Frequency Bandwidth, an ambient hip hop group on the Malicious Damage label.
