Question: Passage: The Croatian language is Croatias official language, but the languages of constitutionally-recognised minorities are officially used in some local government units. 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%. Croatias median equivalent household income tops the average Purchasing Power Standard of 2004 enlargement of the European Union, while trailing the EU average. The 2011 census recorded a total of 1.5 million private households; most owned their own housing.
Question: How many, in percent, more of Croatians belonged to the Roman Catholic Church than Islam ?

Answer: number


Question: Passage: Following the withdrawal of the SNA, the WSLF continued their insurgency. By May 1980, the rebels, with the assistance of a small number of SNA soldiers who continued to help the guerrilla war, controlled a substantial region of the Ogaden. However, by 1981 the insurgents were reduced to sporadic hit-and-run attacks and were finally defeated. In addition, the WSLF and SALF were significantly weakened after the Ogaden War. The former was practically defunct by the late 1980s, with its splinter group, the Ogaden National Liberation Front  operating from headquarters in Kuwait. Even though elements of the ONLF would later manage to slip back into the Ogaden, their actions had little impact. For the Barre regime, the invasion was perhaps the greatest strategic blunder since independence, and it weakened the military. Almost one-third of the regular SNA soldiers, three-eighths of the armored units and half of the Somali Air Force  were lost. The weakness of the Barre administration led it to effectively abandon the dream of a unified Greater Somalia. The failure of the war aggravated discontent with the Barre regime; the first organized opposition group, the Somali Salvation Democratic Front , was formed by army officers in 1979. The United States adopted Somalia as a Cold War ally from the late 1970s to 1988 in exchange for use of Somali bases, and a way to exert influence upon the region. A second armed clash in 1988 was resolved when the two countries agreed to withdraw their militaries from the border.
Question: When did the WSLF lose control over a substantial region of the Ogaden?

Answer: date


Question: Passage: The profound demographic and economic changes that occurred in Finland after World War II affected the Finnish family. Families became smaller, dropping from an average of 3.6 persons in 1950 to an average of 2.7 by 1975. Family composition did not change much in that quarter of a century, however, and in 1975 the percentage of families that consisted of a man and a woman was 24.4; of a couple and children, 61.9; of a woman with offspring, 11.8; of a man and offspring, 1.9. These percentages are not markedly different from those of 1950. Change was seen in the number of children per family, which fell from an average of 2.24 in 1950 to an average of 1.7 in the mid-1980s, and large families were rare. Only 2 percent of families had four or more children, while 51 percent had one child; 38 percent, two children; and 9 percent, three children. The number of Finns under the age of 18 dropped from 1.5 million in 1960 to 1.2 million in 1980.
Question: Was the average number of persons in a family smaller in 1950 or 1975?

Answer:
date
