Angela told her mother that she would be moving out of the house. Her mother's teary-eyed stare changed into a cold, furrow-browed stare as she crossed her arms. Angela knew her mother was not going to let her move out. This example best illustrates

c. that each nonverbal code rarely operates alone.

Explanation:

Words do not tell everything. The important part of the communication is nonverbal communication which includes gestures, mimics, eye contact, facial expressions and posture. People can control what they are going to say, but it is rare that person can control their nonverbal reaction to something. When we want to value verbal communication in making an impression, then we pay attention to tone of voice also. In the given situation, Angela's mother showed her disagreement with Angela's plan to move out without any words using eye contact and body language. So she used at least two nonverbal codes which makes C the most accurate answer.

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
