Input: Question: How long is the river whose floodplain is near the Story Mound? Passage 1:The See of Tyre was the most prestigious archbishopric under the authority of the patriarchs of Antioch from the 5th century. The archbishops had more than a dozen suffragans, including the bishops of Acre, Beirut, Jubail, Sidon, Tripoli and Tortosa. The crusaders captured Tortosa (now Tartus in Syria) in 1102, Jubail in 1103, and Tripoli in 1109. In the late 1170s, William of Tyre wrote that Bernard of Valence, the Latin Patriarch of Antioch, had soon appointed Latin bishops to the three bishoprics. Documents written in the early 12th century did not refer to the bishops of the three dioceses, suggesting that the three sees, all located in the newly established crusader County of Tripoli, were actually left vacant. After King Baldwin I of Jerusalem captured Sidon and Beirut in 1110, Ghibbelin of Arles, the Latin Patriarch of Jerusalem, convinced Baldwin I to ask Pope Paschal II to place the two sees and also the bishopric of Acre under the jurisdiction of the patriarchs of Jerusalem. Accepting the king's argumentation, the Pope ruled on 8 June 1111 that the boundaries of the ecclesiastical provinces should follow the political frontiers. Patriarch Bernard protested, but the Pope confirmed his decision, emphasizing his right to alter the boundaries of the patriarchates.
 Passage 2:The Story Mound is a Native American mound in the southwestern part of the U.S. state of Ohio. Located in the Sayler Park neighborhood of the city of Cincinnati, the mound lies along Gracely Drive. No archaeological excavation has ever been conducted at the mound, and it has remained otherwise undisturbed as well; consequently, the mound remains in pristine condition. Despite the lack of evidence from excavations, the mound has been determined to be a work of the Adena culture, due in part to artifacts such as bones that have been found in the land immediately surrounding the mound. These findings, together with the mound's location near the floodplain of the Ohio River, have been understood as evidence of a larger group of Adena sites in the vicinity of the Story Mound. Such a complex, if it exists, would have great value as an archaeological site; therefore, the Story Mound was listed on the National Register of Historic Places in 1975.
 Passage 3:Continuing to work for DC Comics during this sojourn, while also contributing the occasional story to Warren Publishing's black-and-white horror-comics magazines (including the Don Glut-scripted "Goddess from the Sea" in Vampirella #1, Sept. 1969), Adams had his first collaboration on Batman with writer Dennis O'Neil. The duo, under the direction of editor Julius Schwartz, would revitalize the character with a series of noteworthy stories reestablishing Batman's dark, brooding nature and taking the books away from the campy look and feel of the 1966–68 ABC TV series. Their first two stories were "The Secret of the Waiting Graves" in Detective Comics #395 (Jan. 1970) and "Paint a Picture of Peril" in issue #397 (March 1970), with a short Batman backup story, written by Mike Friedrich, coming in-between, in Batman #219 (Feb. 1970). Adams introduced new characters to the Batman mythos beginning with Man-Bat co-created with writer Frank Robbins in Detective Comics #400 (June 1970). O'Neil and Adams' creation Ra's al Ghul was introduced in the story "Daughter of the Demon" in Batman #232 (June 1971) and the character would later become one of Batman's most common adversaries. The same creative team would revive Two-Face in Batman #234 (Aug. 1971) and revitalize the Joker in "The Joker's Five-Way Revenge!" in Batman #251 (Sept. 1973), a landmark story bringing the character back to his roots as a homicidal maniac who murders people on a whim and delights in his mayhem.
