Final answer:
Miguel from Mexico would find language translation software most useful for understanding a French tourism website, as it provides instant webpage translations.
Step-by-step explanation:
To navigate a tourism website in French, Miguel, who lives in Mexico and does not read or speak French, would most easily benefit from language translation software. This type of software can instantly translate whole pages of content, allowing Miguel to understand detailed information about Angers, France. A French-English dictionary or online language course might also be helpful, but they require more effort and time to use effectively. Travel guidebooks might provide information about Angers, but they may not have the most current details that a local tourism website offers.
