Mr S. : So Diana, have you checked every employees' tasks are well done?
Diana : Yes mister, I have.
Mr S. : Have you checked tennis equipment?
Diana : Yes Mister I have; every thing is fine.
Mr S. : Has Bob made the bed?
Diana : Yes he has; it's perfect.
Mr S. : Have Terry and George bought a new barbecue and cleaned the swimming pool?
Diana : Yes they have. The barbecue is nice and the swimming pool really clean
Tu as tout coché OK, mais de ce que je comprends avec la dernière phrase, il faudrait cocher une case X pour Terry and George:

En espérant t'avoir aidé
