To accurately answer your question, I would need to see the context of paragraph 6 you're referring to. However, based on the options provided, the "shift" could relate to changes in behavior regarding social media.
If the paragraph discusses a change in social behavior, such as how people interact with one another or share information, then:
- A might fit if the paragraph addresses how people are more inclined to document their experiences visually.
- B could apply if the focus is on a decline in face-to-face interactions due to social media use.
- C would be relevant if the paragraph highlights an increase in openness in sharing on social media platforms.
- D would be appropriate if it emphasizes a change in how social media is used, particularly for visual content versus communication.
If you could provide the content of paragraph 6 or more context, I could give you a better answer.
