Problem: Given the question: Information: - Fudan University, located in Shanghai, China, is one of the most prestigious and selective universities in China; It is consistently ranked in the world's top 100 most academic universities. It is also a member in the C9 League. Its institutional predecessor was founded in 1905, shortly before the end of China's imperial Qing dynasty. Fudan is now composed of four campuses in downtown Shanghai, including Handan, Fenglin, Zhangjiang, and Jiangwan, which share the same central administration. - The Qing dynasty, officially the Great Qing, also called the Qing Empire or the Manchu dynasty, was the last imperial dynasty of China, ruling from 1644 to 1912 with a brief, abortive restoration in 1917. It was preceded by the Ming dynasty and succeeded by the Republic of China. The Qing multi-cultural empire lasted almost three centuries and formed the territorial base for the modern Chinese state. - The C9 League is an alliance of nine elite universities in mainland China, analogous to the AAU in the United States, the U15 in Canada, the Russell Group in the UK, and the Go8 in Australia. The members of the C9 League are Fudan University, Harbin Institute of Technology, Nanjing University, Peking University, Shanghai Jiao Tong University, Tsinghua University, University of Science and Technology of China, Xi'an Jiaotong University, and Zhejiang University. Together they account for 3% of the country's researchers but receive 10% of national research expenditures. They produce 20% of the academic publications and 30% of total citations. - Shanghai (": Zanhae" ), often abbreviated as Hu or Shen, is one of the four direct-controlled municipalities of the People's Republic of China. It is the most populous city proper in the world, with a population of more than 24 million . It is a global financial centre and transport hub, with the world's busiest container port. Located in the Yangtze River Delta in East China, Shanghai sits on the south edge of the mouth of the Yangtze in the middle portion of the Chinese coast. The municipality borders the provinces of Jiangsu and Zhejiang to the north, south and west, and is bounded to the east by the East China Sea. - A mathematical problem is a problem that is amenable to being represented, analyzed, and possibly solved, with the methods of mathematics. This can be a real-world problem, such as computing the orbits of the planets in the solar system, or a problem of a more abstract nature, such as Hilbert's problems.<br> It can also be a problem referring to the nature of mathematics itself, such as Russell's Paradox. - A mathematician is someone who uses an extensive knowledge of mathematics in his/her work, typically to solve mathematical problems. - Su Buqing ( ) ( September 23 , 1902 -- March 17 , 2003 ) was a Chinese mathematician and educator . He was born in Pingyang in Zhejiang Province in 1902 . After Su finished high school at Wenzhou High School , he graduated from Tohoku Imperial University in Japan in 1927 and received his Ph.D. from the University in 1931 . He returned to China after his study in Japan , first served as a professor and dean at Zhejiang University ( he established the well - known Chen - Su School with Chen Jian'gong ) , and later as a professor and president and honorary president of Fudan University . He was honorary chairman of the Chinese Mathematical Society and elected to Academia Sinica and Chinese Academy of Sciences in 1948 and 1955 respectively . Together with Hua Luogeng , they were the most influential figures in mathematical society of modern China . Praised commonly in mathematical field as the '' first geometer in the orient '' , Su was engaged in research , teaching and education in differential geometry and computational geometry . In his early years , he made excellent contributions to affine differential geometry and projective differential geometry . He obtained extraordinary achievements in general space differential geometry , conjugating net theory in higher - dimensional space and computer aided geometry design . Given the paragraphs above, decide what entity has the relation 'place of death' with 'shanghai'.

Problem: Given the question: Information: - Pyrrhus II (Greek: ) was the son of Olympias II and Alexander II of Epirus. He was a brother of Ptolemy and Phthia of Macedon. He ruled as king of Epirus from 242 BC to 237 . He had two daughters: Deidamia II was the last ruler of the Aeacid Dynasty and Nereis who married Gelon of Syracuse. - Alexander II was a king of Epirus, and the son of Pyrrhus and Lanassa, the daughter of the Sicilian tyrant Agathocles. - Polyaenus or Polyenus (; see ae () vs. e "Polyainos", "much-praised") was a 2nd-century Macedonian author, known best for his "Stratagems in War" (in Greek, ), which has been preserved. The "Suda" calls him a rhetorician, and Polyaenus himself writes that he was accustomed to plead causes before the emperor. He dedicated "Stratagems in War" to Marcus Aurelius (161180) and Verus (161169), while they were engaged in the Parthian war (162165), about 163 CE, at which time he was too old to accompany them in their campaigns. - Rhetoric is the art of discourse, wherein a writer or speaker strives to inform, persuade or motivate particular audiences in specific situations. As a subject of formal study and a productive civic practice, rhetoric has played a central role in the European tradition. Its best known definition comes from Aristotle, who considers it a counterpart of both logic and politics, and calls it "the faculty of observing in any given case the available means of persuasion." Rhetoric typically provides heuristics for understanding, discovering, and developing arguments for particular situations, such as Aristotle's three persuasive audience appeals, logos, pathos, and ethos. The five canons of rhetoric, which trace the traditional tasks in designing a persuasive speech, were first codified in classical Rome: invention, arrangement, style, memory, and delivery. Along with grammar and logic (or dialecticsee Martianus Capella), rhetoric is one of the three ancient arts of discourse. - Ptolemy ( Greek : ) ; 237 BC - died 234 ) , king of Epirus , was the second son of Alexander II , king of Epirus , and Olympias , grandson of the great Pyrrhus and brother of Phthia of Macedon . He was named in honor of his late uncle Ptolemy , a late brother of his parents . He succeeded to the throne on the death of his elder brother , Pyrrhus II of Epirus , but reigned only a very short time , having set out on a military expedition , during the course of which he fell sick and died . Polyaenus , instead , tells us a different story and states that he was treasonably assassinated . The date of his reign can not be fixed with certainty , but as he was contemporary with Demetrius II , king of Macedonia , it may be placed between 239 and 229 BC. He was succeeded by his niece Deidamia . Given the paragraphs above, decide what entity has the relation 'father' with 'alexander ii of epirus'.
