Input: Consider Input: Passage: Despite the perceived improbability of landfall in the days preceding the storm's passage, the West Palm Beach chapter of the American Red Cross began preparing for the storm. Dr. William J. Buck, likely the only doctor between Pahokee and Moore Haven and also president of the Belle Glade town council and the founder of the town's American Legion post, was skeptical of the Weather Bureau's predictions of the storm missing South Florida. He and his legionnaires warned residents in the Lake Okeechobee region of the approaching cyclone. At South Bay, Frank Schuster made several car trips to save 211 people by transporting them to higher ground. The Seminoles at the Brighton Seminole Indian Reservation in Glades County evacuated to higher ground after observing retreating wildlife. Hours before the storm made landfall, many in the communities surrounding Lake Okeechobee either crowded into a house or evacuated to the building they believed was securest, such as the Belle Glade Hotel, the Glades Hotel, and Henry Martin's store in Belle Glade, with the Glades Hotel sheltering 20 people and the Belle Glade Hotel having nearly 150 refugees. About 500 people in Lake Worth were sheltered inside the Gulf Stream Hotel during the storm. In West Palm Beach, food and thousands of candles, kerosene lamps, and boards were sold on September 16. A number of residents boarded up their homes and then secured their ornamental trees and plants. At the building then being used as the Palm Beach County Courthouse, approximately 500 people sought shelter inside. In Jupiter, 20 people sought refuge in a grocery store, while 25 others stayed at a newly constructed elementary school. A number of African Americans took shelter in a school building in West Jupiter.

Input: Consider Input: Passage: Slavic tribes settled in the Balkan region including North Macedonia by the late 6th century AD. During the 580s, Byzantine literature attests to the Slavs raiding Byzantine territories in the region of Macedonia, later aided by Bulgars. Historical records document that in c. 680 a group of Bulgars, Slavs and Byzantines led by a Bulgar called Kuber settled in the region of the Keramisian plain, centred on the city of Bitola, forming a second route for the Bulgar definitive settlement on the Balkan Peninsula at the end of the 7th century. Presian's reign apparently coincides with the extension of Bulgarian control over the Slavic tribes in and around Macedonia. The Slavic tribes that settled in the region of Macedonia converted to Christianity around the 9th century during the reign of Tsar Boris I of Bulgaria. The Ohrid Literary School became one of the two major cultural centres of the First Bulgarian Empire, along with the Preslav Literary School. Established in Ohrid in 886 by Saint Clement of Ohrid on the order of Boris I, the Ohrid Literary School was involved in the spreading of the Cyrillic.
 Link Information: The 6th century Byzantine historian Jordanes, wrote in his 551 AD work Getica: "although they derive from one nation, now they are known under three names, the Veneti, Antes and Sclaveni" Question: How many different slavic tribes were there in the 6th century?

Output: Answer: 3
