Which of the following is true about nonverbal communication across cultures, according to the readings?
A. All cultures share identical nonverbal communication patterns.
B. Some nonverbal communication patterns are universal while others vary from culture to culture.
C. There has not been enough research on cross-cultural communication to answer this question.

There are nonverbal communication patterns that are not universal, that is, they are recognized anywhere in the world, but this is not a rule, as there are some non-verbal communication patterns that are cultural and change their meaning from one culture to another.

This is because non-verbal communication does not use words to establish itself.

Therefore, to be meaningful, this type of communication usually uses gestures, expressions and objects that are often developed through the customs and culture of each place.

Examples:

The act of lifting your thumb on a road is an element of non-verbal communication, which in American culture represents the request for a ride, but in Brazilian culture it represents the expression "ok."
In some Asian countries, it is common to lower the head as an act of greeting someone. In Western countries, people shake hands with one another.

Based on this, we can conclude that although nonverbal communication has many universal elements, but other elements are adapted to each country's culture, having different meanings in different regions.
