Article: West European scientists judge the Yugoslav language policy as an exemplary one: although three-quarters of the population spoke one language, no single language was official on a federal level. Official languages were declared only at the level of constituent republics and provinces, and very generously: Vojvodina had five (among them Slovak and Romanian, spoken by 0.5 per cent of the population), and Kosovo four (Albanian, Turkish, Romany and Serbo-Croatian). Newspapers, radio and television studios used sixteen languages, fourteen were used as languages of tuition in schools, and nine at universities. Only the Yugoslav Army used Serbo-Croatian as the sole language of command, with all other languages represented in the army’s other activities—however, this is not different from other armies of multilingual states, or in other specific institutions, such as international air traffic control where English is used worldwide. All variants of Serbo-Croatian were used in state administration and republican and federal institutions. Both Serbian and Croatian variants were represented in respectively different grammar books, dictionaries, school textbooks and in books known as pravopis (which detail spelling rules). Serbo-Croatian was a kind of soft standardisation. However, legal equality could not dampen the prestige Serbo-Croatian had: since it was the language of three quarters of the population, it functioned as an unofficial lingua franca. And within Serbo-Croatian, the Serbian variant, with twice as many speakers as the Croatian, enjoyed greater prestige, reinforced by the fact that Slovene and Macedonian speakers preferred it to the Croatian variant because their languages are also Ekavian. This is a common situation in other pluricentric languages, e.g. the variants of German differ according to their prestige, the variants of Portuguese too. Moreover, all languages differ in terms of prestige: "the fact is that languages (in terms of prestige, learnability etc.) are not equal, and the law cannot make them equal".

Question: Of the two Serbo-Croatian variants, which had twice as many speakers as the other?
Ans: Serbian


Article: Like Finnish and Hungarian, Estonian is a somewhat agglutinative language, but unlike them, it has lost vowel harmony, the front vowels occurring exclusively on the first or stressed syllable, although in older texts the vowel harmony can still be recognized. Furthermore, the apocope of word-final sounds is extensive and has contributed to a shift from a purely agglutinative to a fusional language.[citation needed] The basic word order is subject–verb–object.

Question: What language feature does Estonian, Finish and Hungarian share? 
Ans: agglutinative

Article: The Egyptian military has dozens of factories manufacturing weapons as well as consumer goods. The Armed Forces' inventory includes equipment from different countries around the world. Equipment from the former Soviet Union is being progressively replaced by more modern US, French, and British equipment, a significant portion of which is built under license in Egypt, such as the M1 Abrams tank.[citation needed] Relations with Russia have improved significantly following Mohamed Morsi's removal and both countries have worked since then to strengthen military and trade ties among other aspects of bilateral co-operation. Relations with China have also improved considerably. In 2014, Egypt and China have established a bilateral "comprehensive strategic partnership".

Question: How many factories does Egyptian military have?
Ans:
dozens
