It's D! I read this book last year and Cassie wants to gain her trust so she will tell her things and then later betray her.
Mars is a planet (I’m not sure if that’s what you mean)
In this excerpt <u>the speaker expresses his frustration with the fact that even though he doesn't understand the language in which the tune is being sung, he still wishes to comprehend the message</u>. He wants to understand what the singing solitary reaper is singing about.
The conflict here is that they don't speak the same language.
We can see it more clearly in this verse: "Will no one tell me what she sings?" (he doesn't speak the language); and in the rest of the stanza, he keeps on wondering what the song may mean.
Hope this helps!
I believe it is the Iliad by Homer
