Which passage from a narrative most clearly shows a transition in topic? A. On the one hand, I loved him, but on the other hand, his parents
were so mean.
B. She thought she would never see Nadia again. Three
years later,
Nadia returned.
C. Gilbert smirked with satisfaction as he took out his wallet and paid
for the ticket.
D. The construction had been going smoothly. All of a sudden, a
beam collapsed.

the correct answer is:

this is an example of the writer telling through description rather than showing through dialogue.

sometimes writers like to explain explicitely what's happening instead of adding dialogues of the situations., which is the case in this passage,

i think its c or d, its been awhile since i read this book

1. this would be first person. it would be like "i walked home from school today" they are the narrator of the story and is a character as well.

2. first person because they used the word "i" in the quote.

3. i'm really not sure about this one i'm really sorry i never read it so i wouldn't know how to answer it. 

4. it would be character vs. society because everyone he meets there is always a conflict of some sort because he's stuck in his daydream.

5. it would be sadness at the loss of youth because the title itself tells us it's about age so it couldn't be about regret. and the tone just sounds sad, not angry. 

i hope this !
