    If this were true, it would definitely strengthen if not prove the conclusion. But the author doesn't need to assume something this strong. She hasn't claimed that reliance on movies / electronic media renders democracy impossible. So she doesn't need to assume that if you're rely on movies / electronic media that you're unable to form a strong bond with others. It might just be that you're able but unwilling.

  5. Out of Scope: closer to families1% picked this

    People who rely on movies and electronic media for entertainment are generally closer to their families than are

    The only comparison the author is envisioning is that people who rely on movies and electronic media for entertainment are less likely to have strong bonds of mutual trust with fellow citizens (because they are less likely to participate in civic orgs, political parties, or other non-family groups.
