A is the correct answer. Let me explain:
The beginning of sentence "5" starts abruptly with, "I was walking by the dirt lot." If there was a transition into this statement, such as, "Later, when I was walking by the dirt lot..." it would flow better and make room for good writing.
Option 4 is the one which uses a parallel structure:
<span> 4) I also plan to organize more school dances and give my fellow students more opportunities to interact socially.
</span>
A parallel structure is a sentence that uses the same tense or form of a verb throughout. So, number 4 is the only sentence that does that - the other sentences mix a lot of forms and tenses, which shouldn't be done.
Answer
1)The antecedent in this sentence is enjoyed.
2) Pronoun is "i"
Explanation:
Antecedent is a thing that existed before or logically precedes another.
