In the death of ivan ilyich, how does tolstoy set up gerasim to be a foil to praskovya fedorovna in these two excerpts from the death of ivan ilyich?

"gerasim alone did not lie; everything showed that he alone understood the facts of the case and did not consider it necessary to disguise them, but simply felt sorry for his emaciated and enfeebled master. once when ivan ilyich was sending him away he even said straight out: "we shall all of us die, so why should i grudge a little trouble? "—expressing the fact that he did not think his work burdensome, because he was doing it for a dying man and hoped someone would do the same for him when his time came.
. .
when the examination was over the doctor looked at his watch, and then praskovya fedorovna announced to ivan ilyich that it was of course as he , but she had sent today for a celebrated specialist who would examine him and have a consultation with michael danilovich (their regular doctor).
" don't raise any objections. i am doing this for my own sake," she said ironically, letting it be felt that she was doing it all for his sake and only said this to leave him no right to refuse. he remained silent, knitting his brows. he felt that he was surrounded and involved in a mesh of falsity that it was hard to unravel anything."

a)
both gerasim and praskovya fedorovna are honest about their motives, but only gerasim genuinely cares for ivan ilyich.

b)
while gerasim is kind to ivan ilyich and offers him all the he can, praskovya fedorovna is cruel to ivan and torments him.

c)
gerasim attends to ivan ilyich’s needs and gives him all his medicines, while praskovya fedorovna does not care and neglects his health.

d)
both gerasim and praskovya fedorovna want ivan to beat his disease and survive, but only gerasim cares about ivan ilyich’s happiness.
