This translates to “Why is Chapter 3 called "Nobody's Letters"?. I’m pretty sure you’d just have to read the text and figure out why the author chose to name it this.
For question 4 it’s les because it’s plural considering ellas is a group of girls. question 5 is nos because the pronoun is nosotros meaning “we” hope this helps.
I’m wheezing this is spanish not maaatthhh lol
