Qhamisa is my cousin sister who is the most beautiful of them all​

- Qhamisa is my cousin's sister who is the most beautiful of them all.

Explanation:

The given sentence contains a grammatical error in the usage of 'cousin sister.' As per the context of the sentence, the correct form to be employed would be 'cousin's sister' as it is followed by an idea that establishes a comparison. In order to establish the superlative degree, the context of the cousin's must be plural to denote that they are more than two(reflected through usage of all and superlative degree). Thus, the correct sentence would read as:

"Qhamisa is my cousin's sister who is the most beautiful of them all."

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 !
