Final answer:
Without a specific context, it's not possible to definitively state whether every group passes through every stage, as variations exist in development models.
Step-by-step explanation:
The statement that 'every group passes through every stage' can be interpreted in various contexts, such as in biological development, psychological development, organizational development, etc. Without a specific context, it's not possible to definitively state whether this is true or false. However, in many models of development, whether it be of organisms, individuals, or groups, there are recognized stages through which development typically progresses. Yet, it is important to understand that variations exist, and not every group may pass through every stage in a strict sequence.
