Explicación: "I'm sure... didn't" = Deducción negativa basada en pruebas. Usamos can't have + PP.

3. He might have forgotten the meeting.
Explicación: "Perhaps/Maybe" = Posibilidad. Se usa might have + PP.

4. They must have missed the train.
Explicación: "It's certain... did" = Certeza de que algo ocurrió. Usamos must have + PP.

5. I needn't have bought so much food.
Explicación: Acción ya realizada que resultó ser innecesaria. Usamos needn't have + PP.

6. They ought to have told us the truth.
Explicación: "It was wrong not to" = Debería haberse hecho. Usamos ought to have + PP.
