Finalmente, lucia llega a casa a las seis de la tarde y __ muy cansada, pero sabe wue el primer dia de escuela siempre __ dificil.
use estar and/or ser to complete the sentence.

Finalmente, Lucia llega a casa a las seis de la tarde y está muy cansada, pero sabe wue el primer dia de escuela siempre es dificil.

Explanation: Here we need to use correctly the verbs "ser" and "estar"

Nos, "ser" is used for adjetives:

El es alto (he is tall)

and "estar" is used for states or places.

El está en su casa (he is in his house)

El está cansado (he is tired)

Then the complete sentence is:

Finalmente, Lucia llega a casa a las seis de la tarde y está muy cansada (because "cansada" means tired, and this would be a state), pero sabe que el primer dia de escuela siempre es dificil (here we use the verb "ser" because dificil or "hard" is an adjetive).
