A flashback is a <u>narrative device by which a past event is described and inserted into the story, although it does not follow the chronological order of events</u>. The lines that are a flashback are the following:
<em>She thought of her last day in middle school, seven years ago, when Sarah had given her an iPod. She had felt ecstatic that day when she realized she would be able to listen to her favorite songs and fend off comments from her cousins about how little she knew about music.</em>

Marching is the verb. It shows action.
