Ça dépends ton point de vue :
Si c’est oui : Yes, children must have limited access to the internet because they spend too much time on it and they do not spend time with their families and do not focus on school
Si c’est non : No, children do not have to have limited access to the internet because they learn a lot and it is useful for several things
Perso je te conseille de choisir la première proposition mais c’est comme tu veux :)
