Here is a Cultural Literacy worksheet on the tango, the dance that originated on the Rio de la Plata, which forms the natural border between Argentina and Uruguay. I learned, while conducting the modest research this post required, that the tango in 2009 joined the UNESCO Intangible Cultural Heritage List at the proposal of the Argentinian and Uruguayan governments.
In any case, this is a half-page worksheet with a one-sentence reading and one comprehension question; it is the sparest of introductions to a fascinating cultural phenomenon.
