If the privates fail that means Jason and Michelle wil be up for eviction!That's why they want the privates to pass and are motivating them to pass every challenge.

Also the task failures...on last night's highlights show the narrator,Marcus Bentley,said if the housemates fail once more they have failed the task!So I think they fail the task if they fail three times or more in one day which they have done on Saturday!
