Example Input: Context: The Fox River flows from north to south in its first section. The Upper Fox River begins as a small stream northeast of Pardeeville. It flows southwest towards Portage and comes within 2 miles of the Wisconsin River before turning north. After flowing past Montello, the river goes northeast until reaching Lake Butte des Morts. Here it is joined by the tributary Wolf River before entering the west side of Lake Winnebago at Oshkosh. The Upper Fox flows for a total of 142 miles . The Lower Fox begins at the north end of Lake Winnebago, where it flows north past Neenah, Menasha, and Appleton as it begins its 40-mile course northeast towards Lake Michigan. The river drops around 164 feet over this short stretch. Prior to the construction of European-style dams after 1850, the river had many sizable rapids. The Lower Fox ends after flowing through the city of Green Bay and into Lake Michigan through Green Bay. Altogether, the Fox-Wolf watershed drains an area of about 6,429 square miles , giving the Fox an average discharge rate of 4132ft3/s into the bay.

Example Input: Context: The Conquest of Melilla occurred in September 1497, when a fleet sent by the Duke of Medina Sidonia seized the north African city of Melilla., as continuation of Reconquest of Mauritania Tingitana During the 15th century the mediterranean cities of the Sultanate of Fez fell in decadence in opposition to cities located in the Atlantic facade, which concentrated most of the economic activity. By the end of the 15th century, the port of Melilla, that had been often disputed between the rulers of Fez and Tlemcen, was nearly abandoned. Plans for the conquest occurred as soon as the Fall of Granada in 1492. Spanish captains Lezcano and Lorenzo Zafra visited the coast of Northern Africa to identify possible locations for the Spanish to overtake, and Melilla was identified as a prime candidate. Melilla was, however, in the Portuguese zone of influence under the terms of the 1479 Treaty of Alcacovaz. At Tordesillas in 1494, King John II of Portugal, the Portuguese ruler agreed to make an exception and permitted the Spanish to attempt the conquest of Melilla. The duke sent Pedro Estopinan who conquered the city virtually without a fight in 1497, as internal conflicts had depleted it of troops, and its defenses were weakened. The Wattasid ruler Muhammad al-Shaykh sent a detachment of cavalrymen to retake control of the city, but they were repulsed by the guns of the Spanish ships.
