Question: In October, which hurricane had the highest wind speed? Passage:The season featured nine tropical cyclones, of which eight further intensified into tropical storms and six further intensified into hurricanes (including two major hurricanes). Impact throughout the year was widespread. In early July, Hurricane Arthur moved ashore near Cape Lookout, North Carolina, resulting in minor damage and one indirect death. In August, hurricanes Bertha and Cristobal moved across the southwestern Atlantic, causing minimal damage and several fatalities. In September, Tropical Storm Dolly moved ashore the coastline of eastern Mexico, killing one and inflicting unsubstantial damage, while Hurricane Edouard created large swells that impacted the East Coast of the United States and killed two people. In October, hurricanes Fay and Gonzalo moved ashore Bermuda, marking the first time more than one tropical cyclone made landfall on the island in a single season on record.

Question: How long had Ferdinand I been in power the year Coimbra fell? Passage:The history of the county of Portugal is traditionally dated from the reconquest of Portus Cale (Porto) by Vímara Peres in 868. He was named a count and given control of the frontier region between the Limia and Douro rivers by Alfonso III of Asturias. South of the Douro, another border county would be formed decades later when what would become the County of Coimbra was conquered from the Moors by Hermenegildo Guterres. This moved the frontier away from the southern bounds of the county of Portugal, but it was still subject to repeated campaigns from the Caliphate of Córdoba. The recapture of Coimbra by Almanzor in 987 again placed the County of Portugal on the southern frontier of the Leonese state for most of the rest of the first county's existence. The regions to its south were only again conquered in the reign of Ferdinand I of León and Castile, with Lamego falling in 1057, Viseu in 1058 and finally Coimbra in 1064.
