Croatian is the native language identified by 96% of the population. A 2009 survey revealed that 78% of Croatians claim knowledge of at least one foreign language—most often English language. The largest religions of Croatia are Roman Catholic Church (86.3%), Eastern Orthodox Church (4.4%) and Islam (1.5%). Literacy in Croatia stands at 98.1%. The proportion of the population aged 15 and over attaining academic degrees has grown rapidly since 2001, doubling and reaching 16.7% by 2008. An estimated 4.5% of GDP is spent for education. Primary and secondary education are available in Croatian and in the languages of recognised minorities. Croatia has a universal health care system and in 2010, the nation spent 6.9% of its GDP on healthcare. The net monthly income in September 2011 averaged 5,397 Croatian kuna ( ). The most significant sources of employment in 2008 were wholesale and retail trade, the manufacturing industry and construction. In October 2011, the unemployment rate was 17.4%.

[EX Q]: Passage: When the railroad was extended through Madison in 1875, larger mills were built. The first Madison Woolen Mill was constructed in 1881 near the bridge between Madison and Anson, with the firm's second mill built nearby in 1887. In 1890, the Manufacturing Investment Company built a sulfite mill, but it failed. It was taken over in 1899 by the Great Northern Paper Company, which rebuilt the plant to produce wood pulp and paper. Like many New England textile manufacturers, the town's woolen mills eventually went out of business, but the pulp and paper mill remains today as the Madison Paper Industries which will close by May 2016 due to low demand for supercalender paper and Canadian competition.

[EX Q]: Passage: At the beginning of March 1919 the general offensive of the Whites on the eastern front began. Ufa was retaken on 13 March; by mid-April, the White Army stopped at the Glazov-Chistopol-Bugulma-Buguruslan-Sharlyk line. Reds started their counteroffensive against Kolchak's forces at the end of April. The Red 5th Army, led by the capable commander Tukhachevsky, captured Elabuga on 26 May, Sarapul on 2 June and Izevsk on the 7th and continued to push forward. Both sides had victories and losses, but by the middle of summer the Red Army was larger than the White Army and had managed to recapture territory previously lost. Following the abortive offensive at Chelyabinsk, the White armies withdrew beyond the Tobol. In September 1919 a White offensive was launched against the Tobol front, the last attempt to change the course of events. However, on 14 October the Reds counterattacked, and thus began the uninterrupted retreat of the Whites to the east. On 14 November 1919 the Red Army captured Omsk. Adm. Kolchak lost control of his government shortly after this defeat; White Army forces in Siberia essentially ceased to exist by December. Retreat of the eastern front by White armies lasted three months, until mid-February 1920, when the survivors, after crossing Lake Baikal, reached Chita area and joined Ataman Semenov's forces.
