Question: When did Swedish become the official language of the country where the Embassy of France is in the city where Alfred Nobel was born?

<P0-S0> up to 1990, english, german and afrikaans were official languages. <P0-S1> long before namibia's independence from south africa, swapo was of the opinion that the country should become officially monolingual, choosing this approach in contrast to that of its neighbour south africa (which granted all 11 of its major languages official status), which was seen by them as "a deliberate policy of ethnolinguistic fragmentation." <P0-S2> consequently, swapo instituted english as the sole official language of namibia though only about 3% of the population speaks it as a home language. <P0-S3> its implementation is focused on the civil service, education and the broadcasting system. <P0-S4> some other languages have received semi-official recognition by being allowed as medium of instruction in primary schools. <P0-S5> it is expected of private schools to follow the same policy as state schools, and "english language" is a compulsory subject. <P0-S6> as in other postcolonial african societies, the push for monolingual instruction and policy has resulted in a high rate of school drop-outs and of individuals whose academic competence in any language is low. <SEP> <P1-S0> The Embassy of France in Stockholm is the diplomatic mission of the French Republic in Sweden. <P1-S1> The chancery is located at Kommendörsgatan 13. <SEP> <P2-S0> Swedish evolved from Old Norse around the 14th and 15th century, and historically, the Swedish dialects were generally much more different than today. <P2-S1> The Scandinavian languages constitute a dialectal continuum and some of the traditional Swedish dialects could equally be described as Danish (Scanian) or Norwegian (Jamtlandic). <P2-S2> Since the 20th century Standard Swedish prevails throughout the country. <SEP> <P3-S0> the constitution of the fifth republic states that french alone is the official language of the republic. <P3-S1> however, alsatian, along with other regional languages, are recognized by the french government in the official list of languages of france. <P3-S2> a 1999 insee survey counted 548,000 adult speakers of alsatian in france, making it the second most-spoken regional language in the country (after occitan). <P3-S3> like all regional languages in france, however, the transmission of alsatian is on the decline. <P3-S4> while 39% of the adult population of alsace speaks alsatian, only one in four children speaks it, and only one in ten children uses it regularly. <SEP> <P4-S0> The couple married in 1827 and had eight children. <P4-S1> Born in Stockholm, Alfred Nobel was the third son of Immanuel Nobel (1801–1872), an inventor and engineer, and Carolina Andriette (Ahlsell) Nobel (1805–1889). <P4-S2> The family was impoverished, and only Alfred and his three brothers survived past childhood. <P4-S3> Through his father, Alfred Nobel was a descendant of the Swedish scientist Olaus Rudbeck (1630–1702), and in his turn the boy was interested in engineering, particularly explosives, learning the basic principles from his father at a young age. <P4-S4> Alfred Nobel's interest in technology was inherited from his father, an alumnus of Royal Institute of Technology in Stockholm.
