Questions: Red Letter Days encourages Facebook and Twitter followers to post pictures with their mothers and tell why she deserves a day off and a chance win a free lunch at a top London restaurant. In doing so, the restaurant is focusing on which aspect of the 4 E framework?

The answer is "experiencing."

Explanation for each option:

1. Enlightening: This option is incorrect because "enlightening" typically refers to providing new insights or knowledge. The campaign described is more about creating a memorable experience rather than imparting knowledge.

2. Exciting: While the campaign might be exciting for participants, the primary focus is on creating an experience rather than just generating excitement. Therefore, this option is not the best fit.

3. Educating: This option is incorrect because the campaign is not primarily about educating the participants. It is about engaging them in an activity that involves their mothers and a chance to win a lunch.

4. Employing: This option is incorrect because "employing" usually refers to hiring or utilizing resources, which is not relevant to the context of the campaign.

5. Experiencing: This is the correct answer. The campaign encourages followers to share personal experiences with their mothers and offers a chance to win a memorable experience (a free lunch at a top London restaurant). This aligns with the "experiencing" aspect of the $4 E$ framework, which focuses on creating memorable and engaging experiences for customers.
