How do I select an array to loop through from an array of arrays?

#!/usr/bin/bash


ARGENT=("Nous devons économiser de l'argent."
"Je dois économiser de l'argent.")

BIENETRE=("Comment vas-tu?" "Tout va bien ?")

aoarrs=("${ARGENT}" "${BIENETRE}")

select arr in "${aoarrs[@]}"; do
  for el in "${arr[@]}"; do
    echo "$el"
  done
  break
done

I want this script to print the array names to the user, ARGENT and BIENETRE, so that the user can select one of them. After the user's input the script is meant to print every element of an array selected. I want to select with select an array to loop through from an array of arrays (aoarrs). The reason why I want to use select is because in the real world my array of arrays may have many more than just two arrays in it. How might I accomplish that?
