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.

Answer: 3

Passage: On 19 May 1804, Ney received his Marshal's baton, emblematic of his status as a Marshal of the Empire, the Napoleonic era's equivalent of Marshal of France. In the 1805 campaign, Ney took command of VI Corps of the Grande Armée and was praised for his conduct at Elchingen. In November 1805, Ney invaded the Tyrol, capturing Innsbruck from Archduke John. In the 1806 campaign, Ney fought at Jena and then occupied Erfurt. Later in the campaign, Ney successfully besieged Magdeburg. In the 1807 campaign, Ney arrived with reinforcements in time to save Napoleon from defeat at Eylau, although the battle ended in a draw. Later in the campaign, Ney fought at Güttstadt and commanded the right wing at Friedland. On 6June 1808, Ney was created Duke of Elchingen. In August 1808, he was sent to Spain in command of VI Corps and won a number of minor actions. In 1809, he routed an Anglo-Portuguese force under Sir Robert Wilson at Baños. In 1810, Ney joined Marshal Masséna in the invasion of Portugal, where he took Ciudad Rodrigo from the Spanish and Almeida from the British and Portuguese, brusquely defeated a British force on the River Côa, and fought at Bussaco. During the retreat from Torres Vedras, Ney engaged Wellington's forces in a series of lauded rearguard actions (Pombal, Redinha, Casal Novo, Foz d'Arouce) through which he delayed the pursuing enemy forces long enough to allow the main French force to retreat unmolested. He was ultimately removed from his command for insubordination.
