Rule reminder
This exercise tests all advanced subjunctive rules: choice of mood (subjunctive vs indicative), sequence of tenses (present vs past main clause → correct subjunctive tense), concessive/final/conditional conjunctions, relative clauses with indefinite antecedents, and common traps (se, quando, dopo che, same-subject constructions).
Despite the promising start, the project ultimately failed. Choose the correct form: 'Nonostante un inizio promettente, il progetto _____ fallito.'
