How to Make audio Conversations Continue as shown on the timeline without hitting play button

I have the below slide and want to make the audio continue without the user interfering until we get to the question, but when I preview it, it stops after the first person speaks. Can this be fixed?

On entry, the first person speaks, and it stops; what I want to happen is that the second person says, then there is a pause, and the Narrator asks the question of the user, who then selects their choice, selecting the correct choice has a second state that congratulates them, and then moves the screen forward with an Adv Act, The incorrect answer has a second state with an explanation and returns the user to this screen to choose the correct answer, and the first process is completed.  

I want to see if this can be done without making the callout buttons and adding clicks; I just want them to play until the narrator speaks. Any help is appreciated.
