Which of the following queries demonstrates non-visit-in-person intent?

The query "pictures of Madonna" exemplifies non-visit-in-person intent because it indicates that the user is looking for visual content related to Madonna without the necessity or intention to physically go to a location. Users making this type of query are often seeking information or media that can be consumed online, such as images or videos. This shows a preference for digital interactions rather than physical experiences or visits.

In contrast, the other options focus on actions that inherently suggest a physical presence or travel to a location. For instance, queries about visiting the Louvre or seeking directions to the Eiffel Tower indicate an intention to experience these places in person. Similarly, buying concert tickets implies an intention to attend a live event, which also typically requires physical attendance. Thus, "pictures of Madonna" distinctly stands out as the only choice reflecting non-visit-in-person intent.
