Answer:
Tourists.
Step-by-step explanation:
'Sonnet for Heaven Below' is a poem written by Jack Agueros. The poem predicates the life of homeless people, left uncared, and who sleep in the subways tunnels.
These homeless people are described by the author as angels, who are neglected by 'smart New Yorkers.' These angles are not only neglected by New Yorkers but also denied their pay.
Agueros says that 'Mercifully, Angels aren't tourists.'
The poet is saying that the angels thatt he is talking about are not tourists but homeless people.
Thus correct answer is the second option.
