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).
In what city was Zappa's last professional public appearance?

Passage: Immediately after Aaliyah's death, there was uncertainty over whether the music video for "Rock the Boat" would ever air. It made its world premiere on BET's Access Granted on October 9, 2001. She won two posthumous awards at the American Music Awards of 2002; Favorite Female R&B Artist and Favorite R&B/Soul Album for Aaliyah. Her second and final film, Queen of the Damned, was released in February 2002. Before its release, Aaliyah's brother, Rashad, re-dubbed some of her lines during post-production. It grossed US$15.2 million in its first weekend, ranking number one at the box office. On the first anniversary of Aaliyah's death, a candlelight vigil was held in Times Square; millions of fans observed a moment of silence; and throughout the United States, radio stations played her music in remembrance. In December 2002, a collection of previously unreleased material was released as Aaliyah's first posthumous album, I Care 4 U. A portion of the proceeds was donated to the Aaliyah Memorial Fund, a program that benefits the Revlon UCLA Women's Cancer Research Program and Harlem's Sloan Kettering Cancer Center. It debuted at number three on the Billboard 200, selling 280,000 copies in its first week. The album's lead single, "Miss You", peaked at number three on the Billboard Hot 100 and topped the Hot R&B/Hip-Hop Songs chart. In August of the following year, clothing retailer Christian Dior donated profits from sales in honor of Aaliyah.In 2005, Aaliyah's second compilation album, Ultimate Aaliyah was released in the UK by Blackground Records. Ultimate Aaliyah is a three disc set, which included a greatest hits audio CD and a DVD. Andy Kellman of AllMusic remarked "Ultimate Aaliyah adequately represents the shortened career of a tremendous talent who benefited from some of the best songwriting and production work by Timbaland, Missy Elliott, and R. Kelly." A documentary movie Aaliyah Live in Amsterdam was released in 2011, shortly before the tenth anniversary of Aaliyah's death. The documentary, by Pogus Caesar, contained previously unseen footage shot of her career beginnings in 1995 when she was appearing in the Netherlands.In March 2012, music producer Jeffrey "J-Dub" Walker announced on his Twitter account that a song "Steady Ground", which he produced for Aaliyah's third album, would be included in the forthcoming posthumous Aaliyah album. This second proposed posthumous album would feature this song using demo vocals, as Walker claims the originals were somehow lost by his sound engineer. Aaliyah's brother Rashad later refuted Walker's claim, claiming that "no official album [is] being released and supported by the Haughton family.".
"Miss You" was the lead single on which album?

Passage: Albrecht the Elder was 62 or 63  when his panel was painted early in 1490. Barbara's portrait may have been completed soon after, when she would have been around 39. Their son was around 18 and had just completed his apprenticeship with Michael Wolgemut, and would soon leave for Nuremberg to travel as a journeyman painter. The father panel was painted first; for aesthetic reasons Dürer may have waited a year or two until his mother looked older.The sitters are presented in three-quarter view before flat, nondescript lacquer-like green backgrounds, which although lushly coloured, are thinly layered. Each has a white ground and light red imprimatura with lead content. The sitter's form and pose echo and in many ways counterbalance each other. Brand Philip draws attention to the similarities of the panels' linear construction, especially the manner in which the folds and lines of their clothing form triangular shapes. The train of Barbara's headdress across her chest corresponds with the opening of Albrecht's fur-lined coat. It was more usual in pendant portraits of this type for the male to be on the left-hand side; the positioning here may be an indication that Dürer originally intended his father's panel to stand alone, given that Barbara's was painted some time later.Albrecht the Elder's panel is regarded as the superior of the two works. This may in part be attributed to differing contemporary treatments of male and female portraits; men were allowed more individuality, while female portraits were bound by stereotypes and were not as daring, for example showing evidence of ageing. In either case, the father painting is far more closely detailed, especially in the lining of clothing, which is summary in Barbara's panel, compared to the long seam of her husband's gown. This contrast in detail can also be seen in the treatment of the rosaries, which are given prominence and a glowing red colour in his panel, but are small and relegated in hers.Albrecht the Elder's panel is usually, but not always, thought to be the first of the two to be executed and, if so, is the earliest extant example of his son's painting. In contrast, a number of art historians have noted that his mother's portrait contains bland passages, especially around the eyes and may be a near-contemporary copy of a lost original. Lotte Brand Philip believes the clumsiness in the mother panel indicated that Dürer painted it first, as a youthful attempt at portraiture, and that Albrecht the Elder might have later "commissioned" his own portrait to pair with Barbara's. Recent technical examination of the two panels confirms that Barbara's portrait was painted later than her husband's.
What is the name of the person that completed his apprenticeship with Michael Wolgemut?
