Select all sentences that correctly use unless, as long as or provided for an open future condition.

The courtyard can host the market as long as the exits remain clear.✓Correct answer
Provided the soloist will recover by Friday, the rehearsal can proceed as scheduled.
Unless the permit expires this week, the restoration team may continue.✓Correct answer

The courtyard and permit sentences correctly use present forms inside open future conditions. The greenhouse sentence wrongly places would after unless, while the rehearsal sentence wrongly places will inside a provided-clause.
