It is called the diction.
Angst, in writing, is like a dark story. One that has a sad, dark, etc. plot to it. On the other hand, tone is how a writer feel towards a topic.
The correct answer is paradox.
Paradox is a figure of speech that combines two completely opposite things into one. In the excerpt above, we can see that the speaker is willing to wait for his/her loved one his/her entire life, however, only if they don't take too long to get to him/her. This is a paradox because they weren't willing to wait for them long in the first place, as it turns out.
The correct option is this: THE NARRATOR THINKS SHE NEEDS REST, BUT LEN THINKS WORK IS THE CURE FOR HER ILLNESS.
From the excerpt given above, it can be seen that the narrator is sick and the only cure she needs is rest from her works, for she has been doing too much work. But her husband thinks that she needs to continue working because the only medicine she needs as cure is work.<span />
