The problem: Answer a question about this article:
South Slavic dialects historically formed a continuum. The turbulent history of the area, particularly due to expansion of the Ottoman Empire, resulted in a patchwork of dialectal and religious differences. Due to population migrations, Shtokavian became the most widespread in the western Balkans, intruding westwards into the area previously occupied by Chakavian and Kajkavian (which further blend into Slovenian in the northwest). Bosniaks, Croats and Serbs differ in religion and were historically often part of different cultural circles, although a large part of the nations have lived side by side under foreign overlords. During that period, the language was referred to under a variety of names, such as "Slavic", "Illyrian", or according to region, "Bosnian", "Serbian" and "Croatian", the latter often in combination with "Slavonian" or "Dalmatian".
What is "Illyrian?"
****
The answer: language

Question: Read this and answer the question

Britain now threatened to withdraw its subsidies if Prussia didn't consider offering concessions to secure peace. As the Prussian armies had dwindled to just 60,000 men and with Berlin itself under siege, Frederick's survival was severely threatened. Then on 5 January 1762 the Russian Empress Elizabeth died. Her Prussophile successor, Peter III, at once recalled Russian armies from Berlin (see: the Treaty of Saint Petersburg (1762)) and mediated Frederick's truce with Sweden. He also placed a corps of his own troops under Frederick's command This turn of events has become known as the Miracle of the House of Brandenburg. Frederick was then able to muster a larger army of 120,000 men and concentrate it against Austria. He drove them from much of Saxony, while his brother Henry won a victory in Silesia in the Battle of Freiberg (29 October 1762). At the same time, his Brunswick allies captured the key town of Göttingen and compounded this by taking Cassel.

How many troops did Frederick have left?
Answer: 60,000 men


Celtic tribes settled in Switzerland between 1000 to 1500 BC. The Raetians lived in the eastern regions, while the west was occupied by the Helvetii and the Allobrogi settled in the Rhone valley and in Savoy. Among the many substances Celtic tribes mined was salt in areas such as Salzburg in Austria where evidence of the Hallstatt culture was found by a mine manager in the 19th century. By the 6th century BC the La Tène culture was well established in the region, and became known for high quality decorated weapons and jewelry. The Celts were the most widespread of the mountain tribes—they had warriors that were strong, tall and fair skinned skilled with iron weapons, which gave them an advantage in warfare.
Which were the most widespread of the mountain tribes?
The Celts
