If only this were true.
Would 'across' the world also work here? It is marked as incorrect.
That would be "trans", I believe.
Could it be "Through the world there exist universities, which teach Esperanto."?
Similarly, I tried "Through the world, universities exist which teach Esperanto", but it was marked wrong. I don't know if this answer should be accepted or not, though.
Should be that, not which.
Yeah, and also ones that are teaching Klingon.
US universities with multidisciplinary studies, I think.
Any specific ones in mind that you know about?
