Which two words in this excerpt from “preludes” by t. s. eliot appeal to a person's sense of hearing?

the winter evening settles down
with smell of steaks in passageways.
six o’clock.
the burnt-out ends of smoky days.
and now a shower wraps
the grimy scraps
of withered leaves about your feet
and newspapers from vacant lots;
the showers beat
on broken blinds and chimney-pots,
and at the corner of the street
a lonely cab-horse steams and stamps.
and then the lighting of the lamps.

a. smell

b. shower

c. grimmy

d. beat

e. stamps
