I know in Canada is mandatory to take French (our countries official second language) from -I think - 3rd grade all the way up to 9th grade. After that you have the option to continue taking it if you want to.
Doesn't the USA have something similar for Spanish? I always assumed they did, but that could just be because of tv shows lol. It wouldn't be shocking if she spoke some Spanish if that's the case.
Lois did visit the Congo. She may have picked up some French, which is widely spoken there. I think Swahili is also spoken in the Congo, along with a few others.
