Advertisement: In a carefully controlled study, blindfolded volunteers were divided evenly into five groups  Each volunteer tasted Sparkle Cola and one of five competing colas, each group tasting a different cola  Most of the volunteers said they preferred Sparkle Cola to the competing cola tasted
This shows that Sparkle Cola elicits a more favorable response from consumers than any of the competing colas tested
It is based on a study that does not elicit consumers' responses to any beverages other than colas.
