"Rehema is a Kenyan name."
Translation:Rehema ni jina la Mkenya.
The answer means that Rehema is a kenyan's name. A kenyan name is jina la kikenya.
Thank you for the correction. I hope Duolingo invests more into the course.
No, sadly that is not true. Swahili doesn't have any articles (an/the etc.), so the word "a" is not translated in this sentence. On the other hand, this makes for really simple grammar: Rehema is name of Kenya.
