3. Recent statistics make it seem unlikely that the
total consumption of electricity determines its
cost to individual consumers. Recent increases
in total consumption, especially during the hot
summer months, have sometimes been
accompanied by a decrease in the cost per unit
and at other times by an increase.
Which of the following positions is best
supported by the information presented above?
(A) It must be the case that the cost of
electricity to consumers is what
determines the total consumption.
(B) Even though a correlation exists between
the total consumption of electricity and its
cost to consumers, no causal relation
exists.
(C) Further investigation into the way these
statistics were gathered is certainly called
for.
(D) The cost of electricity depends upon
something other than the total
consumption of electricity.
(E) The cost-per-unit of electricity to
consumers is dependent on the total
electricity consumption
