In experimental physics, reverberation produces echo and thus makes undesirable sound. An echo is a sound reflected off of a surface. In a big hall, it interferes with the actual sound. It gives confusion when people are having a conversation.
The answer to the statement above would be TRUE. Both agitation and discomfort can lead to any undesirable behavior and in order to prevent this from happening, certain helping behaviors are highly encouraged in order to promote a positive approach for this response. Hope this helps.
