I think that the most important thing is that you explain why you want to be in the program. It seems that at the masters level, research is not as huge as a focus so I think that as long as it is clear why you want to be in that specific program, then you will be fine. I am applying to the latin american studies programs and I think I will jsut talk about my study abroad experiences and how they lead me to mayan languages and why I want to learn indigenous languages and study indigenous cultures.
