"Who fights now?"
Translation:누가 지금 싸워?
I had both [누가] [지금] [싸워] and [누가] [지금] [싸워요] for an option (among others, of course) -- and decided in favour of the latter. Baaam - wrong again. This is bad. Teaching learners less usable forms while marking those more often used wrong... really needs to be corrected. Please avoid this kind of false negatives. Thanks.
In spoken korean, syntax isn't very important, so when you get more advanced in Korean you can mix it up a lot. But until you get that kind of 'sense' from listening and practicing a lot the more common/grammatically correct written syntax is "now" not at the end and verb always at the end!
