Translation:Nurses often wear white uniforms.
FALSE!!! Nurses almost never wear white. Doctors wear white. The nurses are always in blue, at least around here!!!!!!!
But in russia it is true. They all and doctors and nurses wear white mostly.
This is a language course, not the news. Sentences don't have to be semantically true or not, just to teach us correct grammar.
Color of nurses' uniforms depends on the unit where I work. Navy, light blue, green, purple, fun cartoon patterned (if a pediatric unit), and yes, even white. But this is Duo, and I wouldn't expect the volunteers to account for every possibility.
