The media element supports the purpose of the document by <em>anticipating possible conflicts over choices of destination.</em> <u>The correct answer is D.</u>
Explanation:
The purpose of the document, as we can see in the title, is to prepare readers for a road trip. One of the most important things when preparing for one of these experiences is to agree with our group what kind of trip we want; the pictures and the lines under them show the reader how we can imagine different things from the same concept of "<em>road trip</em>", and by doing this, the author anticipates a possible conflict because he/she shows the reader the importance of being clear about what we have in mind when planning a road trip.
