Executive: In order to add to our profits, I was planning to promote and distribute herbal tinctures  However, some members of my advisory staff questioned the medical efficacy of such products  So I have consulted a variety of reliable medical publications, and these likewise claim that herbal tinctures are ineffective
Ttherefore, I must conclude that marketing such products would not produce the result I intended
Consulting reliable publications is not, by itself, a reliable basis for determining whether or not the promotion of a new line of products will be profitable.
