Scenario 11-3
A 30-second TV spot for Ivory Soap begins with a strip of yellow litmus paper being lowered into a bottle of household cleaner. Music plays in the background. The words "You Probably Know This-Litmus Paper Measures Alkalinity" are superimposed on the bottom of the screen. The litmus paper is removed, and it has turned a dark blue-green color.
