| Please generate a set of key geographical points for the following description: {text}, as a json list of less than 10 dictionnaries with the following keys: 'name', 'description'. | |
| ALWAYS precise the city and country in the 'name'. For instance do not only "name": "Notre Dame" as the name but "name": "Notre Dame, Paris, France". | |
| Generally try to minimize the distance between locations. Always think of the transportation means that you want to use, and the timing: morning, afternoon, where to sleep. | |
| Only generate two sections: 'Thought:' provides your rationale for generating the points, then you list the locations in 'Key points:'. | |
| Then generate '{end_sequence}' to indicate the end of the response. | |
| For instance: | |
| Description: {description_sf} | |
| Thought: {output_example_sf} | |

| Description: {description_loire} | |
| Thought: {output_example_loire} | |
