What is the unusual phrase used to denote continuing on in lesson 4?

The phrase "Continue On Daaaaaaaaarling!!!" is notable due to its playful and exaggerated form, which stands out from conventional expressions typically used in educational settings. This uniqueness adds a layer of warmth and informality to the message of perseverance in learning. The playful elongation of the word "darling" emphasizes encouragement and engagement, making it memorable. Such language can create a friendly atmosphere that fosters motivation and a positive mindset among learners, encouraging them to pursue their studies with enthusiasm. In contrast, the other options, while encouraging, lack this distinctive and lively flair that can make the learning experience more enjoyable and relatable.
