Input: Article: Near the northern Greek borders there are also some Slavicspeaking groups, locally known as Slavomacedonian-speaking, most of whose members identify ethnically as Greeks. Their dialects can be linguistically classified as forms of either Macedonian Slavic or Bulgarian. It is estimated that after the population exchanges of 1923, Macedonia had 200,000 to 400,000 Slavic speakers. The Jewish community in Greece traditionally spoke Ladino (Judeo-Spanish), today maintained only by a few thousand speakers. Other notable minority languages include Armenian, Georgian, and the Greco-Turkic dialect spoken by the Urums, a community of Caucasus Greeks from the Tsalka region of central Georgia and ethnic Greeks from southeastern Ukraine who arrived in mainly Northern Greece as economic migrants in the 1990s.

Now answer this question: Macedonia has how many Slavic speakers?

Output: 200,000 to 400,000

Input: Article: Society throughout Europe was disturbed by the dislocations caused by the Black Death. Lands that had been marginally productive were abandoned, as the survivors were able to acquire more fertile areas. Although serfdom declined in Western Europe it became more common in Eastern Europe, as landlords imposed it on those of their tenants who had previously been free. Most peasants in Western Europe managed to change the work they had previously owed to their landlords into cash rents. The percentage of serfs amongst the peasantry declined from a high of 90 to closer to 50 per cent by the end of the period. Landlords also became more conscious of common interests with other landholders, and they joined together to extort privileges from their governments. Partly at the urging of landlords, governments attempted to legislate a return to the economic conditions that existed before the Black Death. Non-clergy became increasingly literate, and urban populations began to imitate the nobility's interest in chivalry.

Now answer this question: What noble interest did city-dwellers start to mimic in this period?

Output:
chivalry
