EXERCISE (NON OBJECTIVE): We don't really know what language proficiency is but many people have talked about it for a long time. Some researchers have tried to find ways for us to make teaching and testing more communicative because that is how language works. I think that language is something we use for communicating, not an object for us to study and we remember that when we teach and test it.
CORRECT: The issue of language proficiency has been on the rise over the past years. Researchers have demonstrated ways of making language more communicative and interactive in order to increase its fluency without having to study or remember when teaching or testing it.
