which source would be most appropriate for researching the question \how does social media affect personal relationships?\
○ a blog post discussing the bloggers large number of followers
○ a journal article by a psychologist who is studying social media
○ a social media site showing the process of connecting to other users
○ a wiki page discussing appropriate interactions on the internet

Explanation:

A journal article by a psychologist studying social media is academic and research - based. A blog post is personal and may lack objectivity. A social media site's process of connecting is more about functionality, not the impact on relationships. A wiki page on appropriate interactions is too general and not focused on the impact on personal relationships.

Answer:

a journal article by a psychologist who is studying social media
