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: 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 Output:
In what city was Zappa's last professional public appearance?

Passage: The most significant early research of Early Netherlandish art occurred in the 1920s, in German art historian Max Jakob Friedlander's pioneering Meisterwerke der Niederlandischen Malerei des 15. und 16. Jahrhunderts. Friedlander focused on the biographical details of the painters, establishing attribution, and examining their major works. The undertaking proved extremely difficult, given the scant historical record of even the most significant artists. Fellow-German Erwin Panofsky's analysis in the 1950s and 1960s followed and in many ways challenged Friedlander's work. Writing in the United States, Panofsky made the work of the German art historians accessible to the English-speaking world for the first time. He effectively legitimized Netherlandish art as a field of study, and raised its status to something similar to the early Italian renaissance.
Panofsky was one of the first art historians to abandon formalism. He built on Friedlander's attempts at attribution, but focused more on social history and religious iconography. Panofsky developed the terminology with which the Netherlandish paintings are usually described, and made significant advances identifying the rich religious symbolism especially of the major altarpieces. Panofsky was the first scholar to connect the work of Netherlandish painters and illuminators, noticing the considerable overlap. He considered the study of manuscripts to be integral to the study of panels, though in the end came to view illumination as less significant than panel painting as a prelude to the truly significant work of the northern artists of the 15th and 16th centuries.Otto Pacht and Friedrich Winkler continued and developed on Panofsky's work. They were key in identifying sources of iconography and ascribing attribution, or at least differentiating anonymous masters under names of convenience. The paucity of surviving documentation has made attribution especially difficult, a problem compounded by the workshop system. It was not until the late 1950s, after the research of Friedlander, Panofsky and Meyer Schapiro, that the attributions generally accepted today were established.

Ex Output:
What is the full name of the person who effectively legitimized Netherlandish art as a field of study?

Passage: The film focuses on the cast and crew of a new TV series called Manhattan, which is shot on location in New York City. Mel Wexler is a successful producer who has become a workaholic since the death of his family in a plane crash. Trying to forget his loss, he throws himself on producing Manhattan. For the lead role, he tries to cast the feared film star Sabina Quarles, who has a reputation of being hard to work with. She initially declines, explaining she is too good for television. However, because of her past with Mel, she finally accepts the role. They soon start a relationship, but he remains suspicious of her constant visits to San Francisco. She is reluctant to explain why she is going there every month, which makes him think she has an affair.
Meanwhile, playing her stepson in the series is Bill Warwick, an actor who is a sex symbol. He is married to Sandy, but because of his image, he has to keep their marriage a secret. Sandy was once a great actress, but her drug addiction has turned her into a street prostitute, ignoring her work. He thinks a co-starring role could help her going towards the right path, but she fails to show up at her audition. The role eventually goes to Gaby Smith, a rich actress who graduated from Yale. From the very beginning, Bill is upset that his wife wasn't given the role and as a result, treats Gaby very badly. This makes her very sad, constantly trying to win his trust over.

Ex Output:
What does Sandy do to make Bill keep their marriage secret?
