Which pair of words in this excerpt from emily dickinson's "i felt a funeral in my brain" exhibit slant rhyme?

i felt a funeral, in my brain,
and mourners to and fro
kept treading – treading – till it seemed
that sense was breaking through–

and when they all were seated,
a service, like a drum –
kept beating – beating – till i thought
my mind was going numb –

and then i heard them lift a box
and creak across my soul
with those same boots of lead, again,
then space – began to toll,

the words with the big letters are the choices
