In this lesson one of the questions was "Marie a manqué l'école ". I would have answered this with "Marie (has) missed school." Of course this answer wasn't available and the right answer was "Marie didn't go to school." Wouldn't this be easier to understand if written like " Marie n'est pas alleé à école ?" or are all similar events ( not going/doing somewhere/something) expressed by  "Manquer de ?" Thanks,  Heather.
