The correct answer is C. Typical North Americans do not like to interact with each other at all.
Explanation
The text mainly talks about the conception that North Americans have about the air space that surrounds them, which is popularly known as personal space. Regarding this, the author clarifies that "Typical North Americans carry around with them an air space of about two feet in any direction". Complementarily, he refers to the feeling of North Americans once this space is violated by another person, saying that "They feel uncomfortable when they are bumped or when this air space is penetrated in any way". According to the above, it is possible to infer that the correct answer is C. Typical North Americans do not like to interact with each other at all.
