Michael is giving his friend feedback on her paper. which sections of his review contain constructive feedback?

1)my favorite part of the essay was when you described your grandmother's reaction after finding the frog in her purse because it was so funny and so vivid.
2)however, i thought that the section with the pie-eating contest wasn’t very interesting. it just made me want to stop reading the essay.

3)i would suggest working on word choice, since you used the same words many times in the essay. use a thesaurus to find synonyms if you need to.
4)you should change is the ending. i didn't understand it at all.
what was your grandmother doing with that blanket?
5) i don't usually like essays with lame endings like this one.
