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).

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: When was Hyder Ali's son born? Passage:Bangalore Fort began in 1537 as a mud fort. The builder was Kempe Gowda I, a vassal of the Vijaynagar Empire and the founder of Bangalore. Hyder Ali in 1761 replaced the mud fort with a stone fort and it was further improved by his son Tipu Sultan in the late 18th century. It was damaged during an Anglo-Mysore war in 1791. It still remains a good example of 18th-century military fortification.The army of the British East India Company, led by Lord Cornwallis on 21 March 1791 captured the fort in the siege of Bangalore during the Third Mysore War (1790–1792). At the time the fort was a stronghold for Tipu Sultan. Today, the fort's Delhi gate, on Krishnarajendra Road, and two bastions are the primary remains of the fort. A marble plaque commemorates the spot where the British breached fort's wall, leading to its capture. The old fort area also includes Tipu Sultan's Summer Palace, and his armoury. The fort has provided the setting for the treasure hunt in the book Riddle of the Seventh Stone.
