Sandy is writing a brochure to explain the benefits of buying produce from local farmers at the farmers' market rather than from chain grocery stores.-
(C) statistics about how much money is spent at farmers' markets nationally
Explanation:
The usage of statistical information in the brochure will increase the effectiveness of the as the people reading the brochure have a tendency of observing statistical data.(People read things that are short and precised)
So the information related to statistics about how much money is spent at farmers' markets nationally will make the brochure effective.
Other options like
A. information about how much fuel is saved by not shipping produce long distances
B. a lecture about how important it is to put money into the local economy
D. stories about local farm families who participate in the farmers' market
E. statements to make people feel guilty about not supporting local farmers
are inappropriate because a brochure is a small and compact document of conveying desired information to the public .
