“There Will Come Soft Rains” please help!

The author does a brilliant job of incorporating dramatic irony. This kind
of irony is a little different than the "irony" we usually talk about. Dramatic
irony is when something is made clear to the audience that the characters (in
this case a house of dead occupants) are not aware of which points out some
glaring comparisons to real life. In what way is the poem “There Will Come
Soft Rains" used for dramatic irony? Think about what the poem is portraying
compared to what is actually happening. What does the poem describe and
how does it compare with what has been described thus far?

Read the excerpt from david foster wallace’s infinite jest. my silent response to the expectant silence begins to affect the air of the room, the bits of dust and sportcoat-lint stirred around by the ac’s vents dancing jaggedly in the slanted plane of windowlight, the air over the table like the sparkling space just above a fresh-poured seltzer. the coach, in a slight accent neither british nor australian, is telling c.t. that the whole application-interface process, while usually just a pleasant formality, is probably best accentuated by letting the applicant speak up for himself. in this excerpt, the narrator is providing a, both objective descriptions and subjective commentaries. b. only objective information about people, setting, and events. c. only subjective responses to the things he sees and experiences. d. a compromised interpretation of events due to his unstable condition.
