Please do not take my word on this because i am no 100% sure but i think it is B because he is using a metaphor to compare his life to crystal stairs.
Answer: The Aurora
Explanation:
The Aurora was the first steamboat of the year for the Outside, and her decks were jammed with prosperous adventurers and broken gold seekers, all equally as mad to get to the Outside as they had been originally to get to the Inside. Near the gang-plank, Scott was shaking hands with Matt, who was preparing to go ashore.
I would say B.
explanation: since the question is referring to asking the question to your audience, you want to make it easier for them to understand. it could be c, but also you’re asking what they might know about your topic, so making a map to illustrate your points so people who don’t understand it, can understand it. if that makes sense?
hope this helped!!
