I think it's C, because rehearsing discussion responses, presumably in your head, doesn't advance the discussion.
Answer:
How do these lines evoke a sense of time and place in which this poem is set?
B) The mention of the "midnight sun" and men who "moil for gold" indicates that the poem takes place during the Klondike Gold Rush in the Yukon in the late nineteenth century.
Explanation:
In Yukon territory, north of the Arctic Circle, a phenomenon called the Midnight Sun occurs from June to September. The sun does not really set during summer, remaining visible even at midnight. Since the author of the poem mentions the Midnight Sun, we can safely assume he is talking about a place either north of the Arctic Circle, or south of the Antarctic Circle. How do we know, then, that this is about Yukon? Because of the phrase "moil for gold". The author is talking of the Klondike Gold Rush that took place in the Yukon territory. When news spread that gold had been found in the area, around 10,000 people migrated to Yukon to mine for the valuable metal.
