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.

Question: Passage: Grunge music hit the mainstream in the early 1990s with Soundgarden, Alice in Chains, and Nirvana being signed to major record labels. Grunge fashion began to break into mainstream fashion in mid-1992 for both sexes and peaked in late 1993 and early 1994. As it picked up momentum, the grunge tag was being used by shops selling expensive flannelette shirts to cash in on the trend. Ironically, the non-conformist look suddenly became a mainstream trend. In the fashion world, Marc Jacobs presented a show for Perry Ellis in 1992, featuring grunge-inspired clothing mixed with high-end fabrics. Jacobs found inspiration in the 'realism' of grunge streetwear; he mixed it with the luxury of fashion by sending models down the catwalk in beanies, floral dresses and silk flannel shirts. Unfortunately, this did not sit well with the brand owners and Jacobs was dismissed. Other designers like Anna Sui, also drew inspiration from grunge during the spring/summer 1993 season.In the same year, Vogue did a spread called "Grunge & Glory" with fashion photographer Steven Miesel who shot supermodels Naomi Campbell and Kristen McMenamy in a savanna landscape wearing grunge-styled clothing. This shoot made McMenamy the face for grunge, as she had her eyebrows shaved and her hair cropped short. Designers like Christian Lacroix, Donna Karen and Karl Lagerfeld incorporated the grunge influence into their looks. In 1993, James Truman, editor of Details, said: "to me the thing about grunge is it's not anti-fashion, it's unfashion. Punk was anti-fashion. It made a statement. Grunge is about not making a statement, which is why it's crazy for it to become a fashion statement." The unkempt fashion sense defined the look of the "slacker generation", who "skipped school, smoked pot ... [and] cigarettes and listened to music" hoping to become a rock star one day.

Answer: What is the name of the person that had her eyebrows shaved and her hair cropped short?

Question: Passage: After usurping the throne of the Later Zhou dynasty, Emperor Taizu of Song (r. 960976) spent sixteen years conquering the rest of China, reuniting much of the territory that had once belonged to the Han and Tang empires and ending the upheaval of the Five Dynasties and Ten Kingdoms period. In Kaifeng, he established a strong central government over the empire. The establishment of this capital marked the start of the Northern Song period. He ensured administrative stability by promoting the civil service examination system of drafting state bureaucrats by skill and merit (instead of aristocratic or military position) and promoted projects that ensured efficiency in communication throughout the empire. In one such project, cartographers created detailed maps of each province and city that were then collected in a large atlas. Emperor Taizu also promoted groundbreaking scientific and technological innovations by supporting such works as the astronomical clock tower designed and built by the engineer Zhang Sixun.The Song court maintained diplomatic relations with Chola India, the Fatimid Caliphate of Egypt, Srivijaya, the Kara-Khanid Khanate of Central Asia, the Goryeo kingdom in Korea, and other countries that were also trade partners with Japan. Chinese records even mention an embassy from the ruler of "Fu lin" (, i.e. the Byzantine Empire), Michael VII Doukas, and its arrival in 1081. However, China's closest neighbouring states had the greatest impact on its domestic and foreign policy. From its inception under Taizu, the Song dynasty alternated between warfare and diplomacy with the ethnic Khitans of the Liao dynasty in the northeast and with the Tanguts of the Western Xia in the northwest. The Song dynasty used military force in an attempt to quell the Liao dynasty and to recapture the Sixteen Prefectures, a territory under Khitan control since 938 that was traditionally considered to be part of China proper (Most parts of today's Beijing and Tianjin). Song forces were repulsed by the Liao forces, who engaged in aggressive yearly campaigns into Northern Song territory until 1005, when the signing of the Shanyuan Treaty ended these northern border clashes. The Song were forced to provide tribute to the Khitans, although this did little damage to the Song economy since the Khitans were economically dependent upon importing massive amounts of goods from the Song. More significantly, the Song state recognized the Liao state as its diplomatic equal. The Song created an extensive defensive forest along the Song-Liao border to thwart potential Khitan cavalry attacks.

Answer: What is the name of the person that supported the scientific innovations while in charge?

Question: 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).

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