Answer:
Information overload, time, emotions, and use of slang are considered to be: potential barriers to communication.
Step-by-step explanation:
A barrier is an obstacle, something that hinders the progress of something else. Information overload, time, emotions, and slang are potential barriers, meaning they may hinder communication, but aren't necessarily going to hinder it. Imagine, for instance, that you have just arrived to a car crash site. The victims are not gravely injured, but one of them is really emotional, scared, and stressed out about the situation. This person is more likely to have difficulty communicating, expressing himself. His speech will be more infused with emotions, less likely to be concise, straightforward, and even understandable. He may interrupt himself, scream, become aggressive and so on, all of which hinder communication.
