Rule reminder
In formal Italian texts (official letters, academic papers, institutional reports), gaps must be filled with nominal phrases that match the register. The correct answer will always be a nominalisation or noun phrase — not a verb clause. Pay attention to article contractions, gender agreement, and the specific meaning of each nominalisation.
