    Question Type:

    This answer connects understanding with the evolution of the medium, which is the way that it goes from its current form to its ultimate form. It connects the ideas of the argument, and it thus justifies the reasoning.

    Key Takeaway:
    For Strengthen (Principle) questions, connect the premises to the conclusion and don't overthink it.
  5. E
    One medium can replace Remaining source text redacted.
    Why choice E is not credited
    Incorrect. There's no indication that e-books will have richer and more varied content, just different content.
