Answer:
According to this passage from the poem Out, Out the boy realizes that he is too young to be chopping wood. The right answer is the second one.
Step-by-step explanation:
After reading this passage -and only this passage- the reader can infer that the boy realizes he is too young to be doing that kind of work that requires a lot of physical strength. He realizes he shouldn't be doing that because he is still young and that is a man's work, or someone stronger than him who is just a boy. As the passage says, "he was old enough to know", to realize, that he was doing something that was not right at his age.
By reading this excerpt we can't infer anything about his parents being angry, we don't know how they are or what they will feel about this situation, we don't read anything about which time of day it is, nor if he is hungry and we definitely don't know anything about an injury, so the correct answer must be the second one.
