Which sentence would change the tone of this passage from hopeless to hopeful? tell general howard i do not know his heart. what he told me before, i removed from my heart. the young men cannot tell us yes or no. from where the sun now stands i will continue to fight.

The sentence that would change the tone of this passage from hopeless to hopeful is the last one - From where the sun now stands I will continue to fight.
You can see here that this person is very brave and determined not to give up - they want to keep on fighting to what they believe in. It is quite hopeful, especially when compared to the rest of your options which don't have that kind of different and positive tone to them.

Honestly, I don't like it that much, since you can't make freinds and that kind of stuff. But being here in China, it's really my only option for now. So I do what I have to and I do it well. :)
