I think that it would be option C. She made the main female character a devoted mother to her children. If its wrong please do tell so others can know the right answer if i'm ever wrong. I hope this helps you :)
The answer would be began because if a barricade fell down in the middle of a confrontation and there is something that has to do with a riot it would only make sense that a riot would happen which the answer would be began.
In an essay it should only be one I'm pretty sure, but in a narrative as many as it takes to explain a lesson learned. If you were writing a book your conclusion would be whatever comes to you and whatever you feel the characters would do/say/feel.
