Answer:
Subject: A young boy does his homework but gets it wrong.
Theme: Physical punishment is not only painful but also humiliating.
Step-by-step explanation:
In this passage, we encounter a young boy who says that he has done his homework. However, it is implied that the homework is wrong ("Now we’ll have it right from someone"). It seems like the boy's father, who is a barman, did the homework for him. Because of this mistake, the boy is physically punished, while the teacher and the students make fun of his father's background. This supports the theme that physical punishment is not only painful, but also humiliating.
