If I am writing an expository essay, this is considered my: audience
thesis
task
purpose

c). Task

Explanation:

As per the question, if an individual is writing an expository essay in order to examine an idea, assess the available evidence to discover if the idea has its validity, and then bring forth a worthy argument to display that idea, it is his/her task which he/she might have been assigned to or doing willfully. Such essays aim to depict an idea in a clear, precise, and coherent manner after the required research and analysis so that the readers are informed with accurate and objective information. Thus, option c is the correct answer.

what is   the question

1. this would be first person. it would be like "i walked home from school today" they are the narrator of the story and is a character as well.

2. first person because they used the word "i" in the quote.

3. i'm really not sure about this one i'm really sorry i never read it so i wouldn't know how to answer it. 

4. it would be character vs. society because everyone he meets there is always a conflict of some sort because he's stuck in his daydream.

5. it would be sadness at the loss of youth because the title itself tells us it's about age so it couldn't be about regret. and the tone just sounds sad, not angry. 

i hope this !
