d.The poet compares his students to unruly hounds to illustrate the difficulties of teaching.
Throughout the poem, the class is being compared to a pack of unruly hounds. The teacher is showing that he has been trying to teach the children but it is late and they are itching to get away. This is shown when they are described as tugging on the leash and straining apart. The speaker says that he cannot drive them on another hunt towards something they are not interested in. He is basically giving up on trying to get them to learn anything new.
