For the quote "Do Not Enter," the Impact font would be more appropriate. Impact is a bold, sans-serif typeface designed to grab attention and convey urgency, making it suitable for signage and warnings like "Do Not Enter."
On the other hand, Georgia is a serif font that is more suitable for body text and formal communications, and it may not convey the same level of immediacy or clarity for a warning sign. Therefore, for a strong visual impact in a cautionary context, Impact is the better choice.
