Answer: 1. The only effect advertising will have on primary demand is to slow the rate of decline.
Explanation: Declining markets are those that have gone from maturity - where sales stay flat or may even climb occasionally - to multiple periods where there are decreasing sales. This drop in sales is the first and most obvious sign of a declining market and lower sales quickly lead to other attributes.
Common characteristics of the decline stage include a decrease in sales, an increasing difficulty to make a profit, and a decrease in advertising.
