    <introduction>
      <p>
        These <term>select</term> questions specify a list of extant questions,
        and the reader,
        or Runestone, selects questions from the list to be graded
        (in different ways).
        They are only really functional with a database of students in a course,
        i.e.<nbsp/>when hosted on Runestone.
