Does it have to be "finish the work" or can it also be understood as "finish work"? I know those means different things in English, so it could also be like this in Swahili.
I have seen several examples of them removing correct answers in favour of new suggested answers. Basically, we need a button for "My alternative answer is ALSO correct." Or encourage them to add rather than replace answers if they are not sure which is the correct translation.
But maybe they have responded to an overwhelming majority who report that "Finish work" is the best alternative.
