Task: Question Generation
Input (English): Passage: The Swiss census of 1990 and 2000 asked for the "language of best command" as well as for the languages habitually used in the family, at work, and in school. Previous censuses had only asked for the "mother tongue". In 1990, Romansh was named as the "language of best command" by 39,632 people, with a decrease to 35,095 in 2000. As a family language, Romansh is more widespread, with 55,707 having named it in 1990, and 49,134 in 2000. As a language used at work, Romansh was more widely used in 2000 with 20,327 responses than in 1990 with 17,753, as it was as a language used at school, with 6,411 naming it in 2000 as compared to 5,331 in 1990. Overall, a total of 60,561 people reported that they used Romansch of some sort on a habitual basis, representing 0.83% of the Swiss population. As the language of best command, Romansh comes in 11th in Switzerland with 0.74%, with the non-national languages Serbian language, Croatian language, Albanian language, Portuguese language, Spanish language, English language, and Turkish language all having more speakers than Romansh.
