Answer:
Graham cautioned against the move by the client to roll out the same campaign to markets worldwide because differences in languages, customs, and culture might make the campaign meaningless and ineffective in some markets.
The correct option is E.
Explanation:
For an advertising and promotion campaign to be successful and effective, one of its requirements is that it must pass the message across in a language and manner that the target audience will understand and easily relate to.
With that in mind, the advertising and promotion campaign that Graham made for his client in the United States was tailored to pass the message across to people in United States. This was done in the language and manner that would capture their attention and pass the message across.
Now, since this campaign was for people in the United States, it would be improper to roll out the same campaign to markets worldwide, because it has not been tailored to the needs of people from other countries, and it would not capture their attention nor pass the intended message across to them.
Therefore, rolling out this campaign worldwide would be a waste of resources and a loss to the company.
