PART A: What connection does the author draw between communication style and social acceptance? (In the story learning how to code-switch: humbling, but necessary)

The correct answer is A.

A person's success in social interactions is influenced by how they choose to communicate with others.

According to author, one has to be smart in choosing his communication style when dealing with people. He says that today we are living in multicultural, multiethnic society where we have to adapt the cultural values and select or adjust our communication style based on the people you're dealing with.

He mentions the black people that they speak quite formally when they are with white people but they also use their slang communication style when they are with their friends
