The introduction of helps to advance the plot of Daly's "Sixteen." the boy
the narrator
the shanty
the skates

the boy

Explanation:

The narrator feels hopeful but the boy seems to be more genuine in the answer.  Don't know about shanty or skates but I can guarantee you that the boy is the more accurate answer.

i believe it is "he will always remain extremely timid" if its wrong sorry

the answer should be d) he was one of those young thousands who greeted the war with a certain amount of relief, welcoming the liberation from webs of tangled emotion" since it is the best option because it shows his desire to free himself.

hope this answer you! have a great day.
