Autobiography is the word you're looking for.
A paragraph structure is a way you organize your thoughts into a paragraph. It consists of 3 simple parts: The topic sentence, supporting sentence and the concluding sentence. You add lots of detail to each of these sentences, to make them look complicated.
You can add more detail to the answer yourself explaining more about each sentence.
A.[And, as thy son,/ it falls to me to mark/ The acts, the words, the comments of the crowd./ The commons stand in terror of thy frown,/ And dare not utter aught that might offend,/ But I can overhear their muttered plaints,/ Know how the people mourn this maiden doomed,/ For noblest deeds to die the worst of deaths.]
I think your answer would be C. A lesson about life. Most short stories teach something to the readers.
