Complete with a modal-perfect phrase for a confident past deduction and the verb in brackets: One suitcase is missing, and Dev's train ticket was scanned at dawn. He ___ the early train. (take)
Correct answer
- must have taken
- must've taken
- must’ve taken
Explanation
Must have taken is the confident past deduction supported by both the missing luggage and the scanned ticket. Must had taken is ungrammatical because a modal perfect requires have before the past participle.
