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 part because he was overlooked until the mid-19th century, Velázquez 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 Velázquez; 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.
Velázquez'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 Velázquez displays the female nude—without jewellery or any of the goddess's usual accessories—was echoed in later nude studies by Ingres, Manet, and Baudry, among others. In addition, Velázquez'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 Velázquez'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: In 1916, childhood best friends, Bob Wilson and Fred von Bergen, are test pilots working for an American company that builds bombers for the European allies. Since he is German-born and faces prejudice against his heritage, Fred loses his job and, unable to find other employment, decides to return to Germany to fight for his homeland. Although he has no special attachment to the German cause, Bob quits the aviation company and joins his friend in Germany. 
On their way to a German airfield, Red Cross nurse Alida Hoffman accidentally runs Bob and Fred off the road, Both men are immediately drawn to Alida, especially Bob although Fred is more shy. After Bob's first unsuccessful mission, Captain Wolters, the squadron's tyrannical leader, expresses his doubt about his loyalty but, desperate for pilots, gives him another chance. 
As the United States is drawn into the war, instead of sending him into a crucial air battle, Wolters arrests Bob. Fred, heartbroken that Alida has chosen Bob, quarrels with his friend, calling him a coward. Later, however, Fred allows his friend to escape from a firing squad and flee to the Allied lines. 
To prove his allegiance, Bob leads British bombers to the German base, while Fred is told by Wolters that he must shoot down Bob to prove his loyalty. Neither man is capable of killing the other, and, in the end, Fred sacrifices his life for Bob. After the war, Bob returns to Germany to marry Alida. The newly married couple then returns to the United States, and pay their respects to Fred's mother.
[EX A]: What is the first name of the man that is fired for being German-born?

[EX Q]: Passage: Lennon and Ono moved to New York in August 1971 and immediately embraced US radical left politics. The couple released their "Happy Xmas (War Is Over)" single in December. During the new year, the Nixon administration took what it called a "strategic counter-measure" against Lennon's anti-war and anti-Nixon propaganda. The administration embarked on what would be a four-year attempt to deport him. Lennon was embroiled in a continuing legal battle with the immigration authorities, and he was denied permanent residency in the US; the issue would not be resolved until 1976.Some Time in New York City was recorded as a collaboration with Ono and was released in 1972 with backing from the New York band Elephant's Memory. A double LP, it contained songs about women's rights, race relations, Britain's role in Northern Ireland and Lennon's difficulties in obtaining a green card. The album was a commercial failure and was maligned by critics, who found its political sloganeering heavy-handed and relentless. The NME's review took the form of an open letter in which Tony Tyler derided Lennon as a "pathetic, ageing revolutionary". In the US, "Woman Is the Nigger of the World" was released as a single from the album and was televised on 11 May, on The Dick Cavett Show. Many radio stations refused to broadcast the song because of the word "nigger". Lennon and Ono gave two benefit concerts with Elephant's Memory and guests in New York in aid of patients at the Willowbrook State School mental facility. Staged at Madison Square Garden on 30 August 1972, they were his last full-length concert appearances. After George McGovern lost the 1972 presidential election to Richard Nixon, Lennon and Ono attended a post-election wake held in the New York home of activist Jerry Rubin. Lennon was depressed and got intoxicated; he left Ono embarrassed after he had sex with a female guest. Her song "Death of Samantha" was inspired by the incident.
[EX A]:
What is the last name of the person who collaborated with Ono on Some Time?
