Example Input: 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.

Example Output: 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

Example Input: Question: How many years after Minaj released Pink Friday did she begin her PinkPrint tour? Passage:Throughout the tour, Minaj has incorporated multiple outfits into the show that correlate with the major themes of The Pinkprint. The show usually consists of four major outfits, each of which stylistically represent different segments of the show. For the first section of the show, Minaj is dressed in black lingerie covered with a black polka dot mesh catsuit, and is supported by an all female group of dancers who are also dressed in solid black mesh catsuits. The second section of the show sees Minaj performing in a gold-dipped skirt with matching thigh-high boots, and a gold bra, while her dancers, now both male and female, are dressed in gold attire as well. The designers of the second segment outfit were later revealed to be The Blonds, who created the costume especially for Minaj to perform in while on tour. The third and fourth portions of the show have seen multiple changes in wardrobe throughout the extent of the tour. For the third segment, Minaj has either worn a frilly black dress or a solid pink dress depending on the date of the show. And for the fourth and final segment for the tour, Minaj's ensemble either consists of a jumpsuit that can be described as looking like "a broken pink disco ball" on the front with an all mesh back, or a frilly pink bra with a shiny tutu and pink lace tights. Marissa G. Muller from MTV described the latter of the two outfits as "50% Barbie, 50% Ballerina", while also adding that Minaj looked like "the prettiest ballerina Barbie of them all" alongside her female dancers who were almost identically dressed. Muller also noted that the outfit was reminiscent of Minaj's look around the time she released her debut album, Pink Friday (2010). Overall, Nadeska Alexis, also from MTV, greatly praised Minaj's wardrobe choice for the tour stating that the outfits were "sexy", "elegant", and "sweet".

Example Output: Muller also noted that the outfit was reminiscent of Minaj's look around the time she released her debut album, Pink Friday (2010)

Example Input: Question: What is the total length of the light rail service operated by the Los Angeles County Metropolitan Transportation Authority? Passage:The Los Angeles County Metropolitan Transportation Authority (LA Metro) operates the Blue Line, a light rail service that runs between the Downtown Long Beach Station (known as the Transit Mall Station until July 2013) and the 7th Street/Metro Center station in downtown Los Angeles. From the 7th Street/Metro Center Station, passengers can make connections to Hollywood, Union Station, Pasadena, East LA, Universal Studios, Chinatown, and other points of interest along the Los Angeles Metro Rail network.

The Metro Blue Line also offers connections to the Metro Expo Line at both the 7th Street/Metro Center Station and Pico Station with service to Santa Monica. In addition, at Willowbrook Station, passengers can transfer to the Metro Green Line with service to Redondo Beach, Norwalk, and Los Angeles International Airport via an additional shuttle connection. The Metro Blue Line Maintenance Shops are also in Long Beach just south of the Del Amo Blue Line station.
