To kill a mocking bird

hey all i need help with my english assessment its a bit of a complicated task and i don't quite understand the subject so lets get in to it

the task is to find a gap and silences in the book to kill a mocking bird and explain it further by telling an imaginative story am going to show u guys what i handed in as a draft its a bit of a read am sorry about that now a bit of the context am filling in the gap where boo saves scout and jem from bob ewell so hear we go

“The pageant was a massive failure” says scout “it wasn’t that bad” says jem “not many people realised you arrived late scout” as they keep walking back home from the pageants walking back there usual route still talking about the pageant they where getting close to the boo Radley house, the house of the malevolent phantom boo Radley jem stars feeling a bit uncomfortable even though the fear of boo Radley himself had pass long ago jem had a weird feeling but she didn’t mention anything to scout. “it kind of sucks that the tree next to boo Radleys got filled up with concrete” says scout “yeah, I miss the present we used to get in the whole” all the sudden a bush start rustling and then scout gets attacked from behind when jem starts to scream someone sneaks outs of the boo Radley house to help in all this commotion but who was it?

It was boo Radley, boo Radley sneaks up and pulls scouts attacker away from her he grabs him by the shirt and pulls him down to the ground boo Radley realises who the attacker is, its ben Ewell, the man who threatened scout and jem father days earlier at the post offices and he has a knife, boo Radley puts his hand out signalling Bob Ewell to stop but instead Bob stand up and screams what the “hell are you doing get off me” bob Ewell stands up and pushes jem down making him hit his head before bob can do anything else boo Radley steps in and wrestles bob for the knife but bob hits him and makes boo lose his balance boo wobbles back looks at bob with an intimidating figure cracks his knuckles and jumps on bob he manages to get the knife away from bob but in an act of desperation bob tries one more time to take the knife back but accidently boo stabs him in the chest. Boo Radley realises what he has done he looks down at his hands and sees blood he drops the knife next to bob body he looks upon at what’s he’s done, but in his head he’s thankful he’s saved his friends, and that they are okay and that’s all that matter. he runs over to jem and sees him on the ground boo flips his over and waves his hand in front of jem face he tries to wake him up to no avail.

Boo breathes in deeply grabs one arm and one leg and picks up jem and starts caring him over to the finch house he knocks on the door Atticus opens the door he’s shocked to see his son being carried by boo Radley but without saying a word walks right pass him and puts jem down on the couch Atticus walks over but boo just point to the phone while aunt Alexandra got the doctor Atticus called the sheriff. The doctor helps jem and he wakes up with minor injuries while scout isn’t hurt, boo Radley and the sheriff walk back to the scene of the crime the sheriff sees bob Ewell is body he lets out a massive gasp “ di did you so this Mr Arthur?” says the sheriff boo Radley nods his head “was “he trying to hurt you?” asked the sheriff boo shakes his head then “why would you do something like this?” boo points to the finch house the sheriff realises the real reason he was trying to protect the kids. After examine the body some more he concludes, bob Ewell fell on his knife trying to attack jem and scout finch. The sheriff looks at boo and tells him “I know you did it for a good reason that’s why am covering for you just keep it between us and nothing bad will happen Mr Arthur.” Boo nods his head and goes back to the finch house to be with his only friends jem and scout finch.

now after getting my feedback from my teacher i got this and i don't understand it

This has taken place already. Do you want to write the story from Boo’s perspective?

The reader knows this already. I hope you took on board what I discussed in class today about filling in a gap. You are NOT filling in a gap you are narrating the story.

this feedback bother me as i do not find it to be true or it might be that the task at hand is not explained properly

apart from this i do not know how to act on this feed back help will be very much appreciated as i honestly hate this
