ESL001: SO is a conjunction, isn't? | Saylor Academy

SO is a conjunction, isn't?

In the parts of speech practice section, when I read The paper bag princess text, I had to choose conjunctions in it. In this sentence, "So she put on the bag." I chose SO as a conjunction but it was wrong. I was so confused. Please, explain me why?
