The sentence that should be revised for errors in formal tone and academic language in Kristin's essay is sentence 4.
How do you write in formal tone?
There are several things to keep in mind when writing in formal tone or academic language and one of them is to avoid the use of personal pronouns such as "I" and "me."
Kristen used the person pronoun, "I" in the fourth sentence which goes against this guideline and so the sentence should be revised for that formal tone error.
