Question

Correct the sentence if it is there is no one outside the theatre, the performance have been cancelled

Answer 1

Correct sentence: If there is no one outside, the performance will be canceled.

The tenses rules of multiple clauses:

• If there is present indefinite tense in one clause, the second clause should either be present indefinite or future tense.
• If one clause has past indefinite, the second clause must have past indefinite or past perfect tense.
• There cannot be future tense twice in a sentence.
