Answer: misused pronoun: me. Correct pronoun: I.
Explanation: Pronouns have three possible cases: subjective, possessive and objective. The subjective case is used when the pronoun is the subject of the sentence (they are: I, you, she/he/it, they, we). The objective case is used when the pronoun acts as an object in the sentence (they are: me, her, them, us, etc). The possessive case is used to indicate ownership (they are mine, yours, his, hers, its, ours, and theirs). In the given sentence, the pronoun is in the subject of the sentence, therefore it should be in the subjective case: After school, Bob and I cleaned up their yard.
Varied Sentence Structure. Sentence structure is how you arrange your words, phrases, and clauses in a sentence. Writers who don’t vary their sentences repeat the same sentence subject, length, and type. This repetition bores the reader, and it weakens your voice. Varied sentences give your writing life.
