Complete the sentence with the correct form of the verb in brackets: The editor guarantees that by noon tomorrow she ___ (complete) the final review, and nothing will be left to do after that deadline.
الإجابة الصحيحة
will have completed
الشرح
The guarantee requires the review to be wholly finished before noon, with no work remaining, so the future perfect expresses the completed result. The future continuous would place the review in progress around noon and would therefore fail the strengthened completion premise.
