I don’t know what you are asking but what that mean in English is
“The selfish giant”
“The small boy hurt his hands and feet with the garden rules”
Chica is feminine... reservada is feminine... so which of your options are feminine? Ella and la. Ella means she so it can't work, as that would mean she girl is very reserved. La is the femenine the. So that is your answer.
Siempre is the opposite of nunca
estoy is the right conjugation
estan is the right conjugation
You mean Mexican traditions?
It is correct. "Yesterday I arrived late"
