||If a material
frames sections within a unit (rather than the whole unit), then the
reviewer should evaluate and rate the purpose for each section separately
and take the average. If a material attempts to frame both the unit overall
and large sections within the unit, the reviewer should evaluate and
rate each purpose separately. The overall rating of the criterion will
be the average of the rating of the purpose for the unit overall and
the average rating of the purposes provided for the individual sections.
