Final answer:
The statement is false. Reuben waving his hand when he says 'Good Morning' to his colleagues is subjective and varies from person to person.
Step-by-step explanation:
The statement is false. Reuben waving his hand when he says 'Good Morning' to his colleagues is not a fact that can be answered as true or false. This statement is subjective and can vary from person to person. Some people may wave their hand while saying 'Good Morning' as a gesture of greeting, while others may not. Therefore, if this statement is false, it cannot be rewritten correctly as it is based on personal behavior.
