Nayelee001, jenny110 was referring to the question number 2 in the quiz, not the episode.Jenny, I'm really not sure why it can't be B. I think it's because the semicolon is a BETTER CHOICE. Also, I think it's because ...So as a conjunction has two basic meanings:1. With the result or consequence that: He failed to appear, so we went on without him.2. In order that: I stayed so I could see you.and the better conjunction would have been AND, not SO in question 2's case. It's more logical.
