The narrative structure would be rising action, falling action, climax, and conclusion.I think if this helps.
Explanation:
a shopkeeper bought two hats for rs. 400. he sold them to gain 5% on one ang lose 5% on the other. calculate his final gain or loose percentage if the selling price of both hats is same.
The 1st and 2nd sentence is different because of the word "might" wich is used to tell a possibility.
I also concur that answer B has an error.
B: he was going to give...
So lets rewrite the whole thing. In order to prepare for the speech he was going to give to all of the parents and teachers at the school, George practiced speaking in front of a group of his friends.
After correcting B, the entire sentence flows more nicely. Hopefully this helped and good luck
