Test Debunking Myths: [Intrapersonal] Communication and the Number of People

1st QUESTION: Why is the concept of "intrapersonal communication" considered an inconsistency in the text?

Because the number of people is easy to count and standardize
Because it is a subjective, imprecise and impractical criterion ("several", "many")
Because you can only communicate with one person at a time
Because technology has made the number of participants irrelevant

Internal dialogue is a solitary activity, while communication is an external and collaborative action
Internal dialogue uses words, while communication uses gestures
Communication is a cognitive process, while internal dialogue is a social action
There is no real difference between the two concepts

Because there are always more people listening to the conversation
Because it is a subjective and affective interaction
Because it is objective, it is governed by roles (boss-subordinate) and it is programmed
Because two people are already considered a large group
