Input: Consider Input: Question: Which is the oldest ancient religious text that mentions Tripura? Passage:Although there is no evidence of lower or middle Paleolithic settlements in Tripura, Upper Paleolithic tools made of fossil wood have been found in the Haora and Khowai valleys. The Indian epic, the Mahabharata; ancient religious texts, the Puranas; and the Edicts of Ashoka – stone pillar inscriptions of the emperor Ashoka dating from the third century BCE – all mention Tripura. An ancient name of Tripura is Kirat Desh (English: "The land of Kirat"), probably referring to the Kirata Kingdoms or the more generic term Kirata. However, it is unclear whether the extent of modern Tripura is coterminous with Kirat Desh. The region was under the rule of the Twipra Kingdom for centuries, although when this dates from is not documented. The Rajmala, a chronicle of Tripuri kings which was first written in the 15th century, provides a list of 179 kings, from antiquity up to Krishna Kishore Manikya (1830–1850), but the reliability of the Rajmala has been doubted.

Input: Consider Input: Question: How long had the Chicago Cubs been a team when Mahaffey set a strikeouts record for his club? Passage:Mahaffey set a club record with 17 strikeouts in a game against the Chicago Cubs on April 23, 1961. Though he ended the season with an ERA of 4.10, and a record of 11–19 (leading the NL in losses), in 36 games, he was selected to represent the Phillies on the NL All-Star team. Mahaffey ended the season with a record of 19–14, and a 3.94 ERA, with a career high 177 strikeouts, in 41 games. He was selected again in 1962 for the NL All-Star team, finishing 26th in balloting for NL Most Valuable Player (MVP), despite leading the league in home runs allowed with 36, and earned runs allowed with 120. Mahaffey had a 7–10 record in 26 games with the Phillies, to go along with a 3.99 ERA. In , he finished the season with a record of 12–9, with an ERA of 4.52, in 34 games. The ill-fated 1964 team was in first place in the NL, with a 6-game lead, with just 12 games remaining in the season, before starting a 10-game losing streak that cost the team the pennant. Mahaffey pitched in two of the games in that infamous skid, losing a 1–0 game (the first of that losing streak) on a steal of home by Chico Ruiz of the Cincinnati Reds, and was taken out while winning 4-3 in a game against the Milwaukee Braves, in which Rico Carty hit a ninth-inning bases-loaded triple, plating all 3 runners, off of reliever Bobby Shantz, to win the game for the Braves, 6-4. was his last season in Philadelphia, which saw him finish with a 2–5 record, and an ERA of 6.21, in 22 games, mostly in relief.
