Czy mógłby ktoś sprawdzić to zadanko

Czy mógłby ktoś sprawdzić to zadanko , bo zupełnie nie jestem tego pewien ,muszę wstawić czasowniki w nawiasach w odpowiedniej formie w czasie past simple, present perfect simple , lub present perfect continous.


A : You look really tired . What's wrong?
B : I (study)....have studied.... all morning and I still (not/finish)....have not finished....



A : How long( Brad Pitt/act) ...Brad Pitt has been acting... in Hollywood films.
B : I can't say for sure.


A : Where were you? I (wait) ....waited.... for over an hour.
