Answer:
While Gerasim is kind to Ivan Ilyich and offers him all the help he can, Praskovya Fedorovna is cruel to Ivan and torments him.
Step-by-step explanation:
This is the main difference between the behaviour of Gerasim and the behaviour of Praskovya Fedorovna. In the first excerpt, we see that Gerasim is a kind man who cares about Ivan. He realizes that his illness is something very difficult to tolerate, and tries to help him in any way he can. On the other hand, Praskovya Fedorovna is cruel to Ivan. She talks to him in a way that betrays her selfishness and makes the reader think she does not care for him.
