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.

[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.

[Q]: Question: What were the main groups involved in the event that resulted in the sacking of Constantinople in 1204? Passage:Papal calls for renewed holy war at the end of the twelfth century inspired not only the disastrous Fourth Crusade that sacked Constantinople in 1204, but also a series of simultaneous "Northern Crusades" that are less fully covered in English-language popular history, but which were more successful in the long run. Before the crusades, the region of Livonia was a mixed outpost, a pagan society where merchants from the Hanseatic League encountered merchants of Novgorod, and where Germanic, Scandinavian, and Russian trade, culture, and cults all mingled. The specific ethnic groups that intermingled and traded with the Germans, Danish, Swedish, and Russians here included the Wends, who were merchants from Lübeck, the Estonians, the Karelians, the Kuronians, the Lettgallians, the Semgallians (sometimes known as the Letts), the Livonians and the Lithuanians. The Western merchants would trade silver, textiles, and other luxury goods for furs, beeswax, honey, leather, dried fish, and amber. Livonia had been an especially promising location in terms of resources, and Arnold of Lübeck, in his Chronicle of the Slavs wrote that the land was "abundant in many riches" and was "fertile in fields, plentiful in pastures, irrigated by rivers", and "also sufficiently rich in fish and forested with trees".

[Q]: Question: Is the NFL Europe still in operation? Passage:The longest field goal kick in NFL history is 64 yards, a record set by Matt Prater on December 8, 2013. The previous record was 63, originally set by Tom Dempsey (1970) and then matched by Jason Elam (1998), Sebastian Janikowski (2011), David Akers (2012), Graham Gano (2018), and Brett Maher (2019). The record in the CFL is 62 yards, set by Paul McCallum on October 27, 2001. High school, college and most professional football leagues offer only a three-point field goal; however, some professional leagues have encouraged more rare kicks through four-point field goals. NFL Europe encouraged long field goals of 50 yards or more by making those worth four points instead of three (much like Australian rules' Super Goal or basketball's three-point line), a rule since adopted by the Stars Football League. Similarly, the sport of arena football sought (unsuccessfully) to repopularize the drop kick by making that worth four points; it failed, since only one kicker (Brian Mitchell) was able to do it with any semblance of proficiency. (In six-man football, where there is no offensive line, all field goals are worth four points instead of the usual three.)
