Why do I see tasks to verify but can't see the answer?

Depending on the type of Task Status, the user must have the following privileges in order to see the answers:

• Displaying tasks in verification with the status ‘Accepted’
• Display tasks in verification with the status ‘For verification’
• Displaying tasks in verification with the status ‘Rejected’
• Displaying tasks in verification with the status ‘Rejected and returned’
