The use of heat pumps has been held back
largely by skepticism about advertisers‘ claims that
heat pumps can provide as many as two units of
thermal energy for each unit of electrical energy
used, thus apparently contradicting the principle of
energy conservation. (43 words)

6. If the author‘s assessment of the use of heat pumps is
correct, which of the following best expresses the
lesson that advertisers should learn from this case?
(A) Do not make exaggerated claims about the
products you are trying to promote.
(B) Focus your advertising campaign on vague
analogies and veiled implications instead of
on facts.
(C) Do not use facts in your advertising that will
strain the prospective client‘s ability to
believe.
(D) Do not assume in your advertising that the
prospective clients know even the most
elementary scientific principles.
(E) Concentrate your advertising firmly on financially
relevant issues such as price discounts and
efficiency of operation.
