"So I cook a hamburger."
Translation:그래서 저는 햄버거를 요리해요.
I don't get these multiple choice questions ... every possible answer here starts with 그래서. Only the verb at the end of the sentence differs. Aren't we learning conjunctions? Shouldn't Duo have us pick from three different conjunctions? (Oh, and the tool more often than not has the browser's focus on the correct answer - so much for testing our knowledge.)
When i am not sure, i can sometimes eliminate "wrong" answers by other words I know for certain, like those verbs. Especially when it's the last and only thing I cannot get correct today, that's my method. Then I can review the notes and tips for conjunctions: So unfamiliar and a lot to learn.
