In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

[EX Q]: Question: Did Sparta exist beyond 371? Passage:The scale and scope of warfare in Ancient Greece changed dramatically as a result of the Greco-Persian Wars, which marked the beginning of Classical Greece (480-323 BC). To fight the enormous armies of the Achaemenid Empire was effectively beyond the capabilities of a single city-state. The eventual triumph of the Greeks was achieved by alliances of many city-states, on a scale never seen before. The rise of Athens and Sparta during this conflict led directly to the Peloponnesian War, which saw diversification of warfare. Emphasis shifted to naval battles and strategies of attrition such as blockades and sieges. Following the defeat of the Athenians in 404 BC, and the disbandment of the Athenian-dominated Delian League, Ancient Greece fell under the Spartan hegemony. But this was unstable, and the Persian Empire sponsored a rebellion by the combined powers of Athens, Thebes, Corinth and Argos, resulting in the Corinthian War (395-387 BC). Persia switched sides, which ended the war, in return for the cities of Ionia and Spartan non-interference in Asia Minor. The Spartan hegemony would last another 16 years, until, at the Battle of Leuctra (371) the Spartans were decisively defeated by the Theban general Epaminondas.

[EX Q]: Question: Who was selected as the first pick in the draft that Kleinendorst was chosen 77th? Passage:Kleinendorst played for Providence College for four years, from 197980 to 198283, for Lou Lamoriello. He was selected in the fourth round (77th overall) of the 1980 NHL Entry Draft by the New York Rangers, but never played in the NHL. He was a member of the Tulsa Oilers (CHL) team that suspended operations on February 16, 1984, playing only road games for final six weeks of 198384 season. Despite this adversity, the team went on to win the Adams Cup. In 198687 he played with Iserlohn (Germany) and Peliitat Heinola (Finland) teams, and then with the Rotterdam Pandas in the Netherlands during the 198788 season, Ingolstadt (Germany) 198889, and continued to play minor league hockey through 1990.

[EX Q]: Question: Which Dynasty produced the most mathmaticians? Passage:Four outstanding mathematicians arose during the Song Dynasty and Yuan Dynasty, particularly in the twelfth and thirteenth centuries: Yang Hui, Qin Jiushao, Li Zhi (Li Ye), and Zhu Shijie. Yang Hui, Qin Jiushao, Zhu Shijie all used the Horner-Ruffini method six hundred years earlier to solve certain types of simultaneous equations, roots, quadratic, cubic, and quartic equations. Yang Hui was also the first person in history to discover and prove "Pascal's Triangle", along with its binomial proof (although the earliest mention of the Pascal's triangle in China exists before the eleventh century AD). Li Zhi on the other hand, investigated on a form of algebraic geometry based on tian yuan shu. His book; Ceyuan haijing revolutionized the idea of inscribing a circle into triangles, by turning this geometry problem by algebra instead of the traditional method of using Pythagorean theorem. Guo Shoujing of this era also worked on spherical trigonometry for precise astronomical calculations. At this point of mathematical history, a lot of modern western mathematics were already discovered by Chinese mathematicians. Things grew quiet for a time until the thirteenth century Renaissance of Chinese math. This saw Chinese mathematicians solving equations with methods Europe would not know until the eighteenth century. The high point of this era came with Zhu Shijie's two books Suanxue qimeng and the Siyuan yujian. In one case he reportedly gave a method equivalent to Gauss's pivotal condensation.
