Answer:
The given assertion would be characterized as an empty rhetoric as it offers a hollow premise that lacks adequate backing details to support its validity. It offers an empty statement i.e. 'non-formal institutions do not have a part in the system's processing stage' that attempts to persuade the readers without offering any logical evidence to substantiate the presented viewpoint. Contrarily, the significance of non-formal institutions is clearly evident due to their play in improving social standards, enhancing the environment for learning, teaching them cultural ideologies, etc. Thus, the statement fails to convince the readers.
