Final answer:
In 'The Death of Ivan Ilyich,' Gerasim is a butler who would likely replace a single person, as his role as a domestic worker is typically for one servant.
Step-by-step explanation:
The character Gerasim is from Leo Tolstoy's novella 'The Death of Ivan Ilyich.' In the story, he serves as a young butler to Ivan Ilyich's family.
If Gerasim were to replace someone in a household context, it would likely be a single person, given that he is a domestic worker and his role is typically a one-person job.
It's implied that his duties could cover those of an individual servant, rather than replacing the roles filled by a couple or a whole family.
