Questions & Answers about La guía habló con tanta sinceridad de su ciudad que hasta mi madre quiso volver a esa capital.
Habló is the preterite, which presents the action as a completed event in the past.
So La guía habló... suggests a specific finished moment: the guide spoke, and that had a result.
If you said hablaba, that would sound more like background description or an ongoing past action:
- La guía hablaba con tanta sinceridad... = the guide was speaking so sincerely...
In this sentence, the speaker is focusing on the completed action and its consequence, so habló is the natural choice.
