Although the question does not provide any text or further reference, we can say that one document that paints a more accurate portrayal of Colin Powell can be found in the book "Collin Powell: Military Leader."

Bush administration.
Slogan is pretty much like your ad or logo. It's a type of technique you'd use to get people to believe your product actually does what you say it does. Your slogan is also how people make ads rhyme and make it seem so good.
