I am confused about the word order, Can it be "A politikus sétál ott".? because i saw one sentence where the verb is before the adverb(...áll kint)
Saying it like that would answer the question 'who is walking there?' 'the politician is walking there'. I think Duo wants this to be a sentence on it's own rather than an answer to a specific question :P
(Plus it sounds really unnatural)
If I am not wrong, the order in that case doesn't matter.
