nicely done, zexoin! you get to post the next question :-)
i have to add that before the country was renamed, it was upper volta. i was told that back then the answer was "ouagadougou est au haut volta" (that was later corrected by the french teacher who said countries are referred to in the feminine form - "ouagadougou est a l'haut volta"). it made for a fun chant...
ou est ouagadougou?
ou est ouagadougou?
oui, ou est ouagadougou?
ouagadougou est au haut volta.
ouagadougou est au haut volta?
oui, ouagadougou est au haut volta!
