“Two speakers: one dead and one living”.
Step-by-step explanation:
The poem, “Is My Team Ploughing?” by A.E Housman, is about a conversation that takes place between two friends, one who is dead and the other who is living, and has come to visit him at his grave.
This is depicted or observed by the way the poet writes certain questions in inverted quotations, revealing that they are questions are asked by the friend in the grave, wanting to know how things in the outside world are as he no longer can see or observe them.
