How many components does an advertisement comprise?

Directions: Read the passage and answer the following question:

As every moron knows, an ad comprises words and pictures. The word component is the domain of the copywriter and the visuals, the Art person. Interestingly, although their combined creativity, skills and crafts went into the making/creation of this ad, they functioned separately. This meant that the copywriter wrote his stuff and handed it over to the art person - usually with some guidelines - who then proceeded to visualize it in an appropriate meaningful manner. But you also came from different social stratospheres. The copywriter, usually, came from a convent/public school background, was fluent in English and totally comfortable with both the command and nuances of the language.
